Hi,
In plain consumer devices - such as an ASUS wireless router - the out-of-the-box firewall state is usually one which does not require any changes for a normal user.
It accepts all outgoing connections, and only accepts incoming packets from established connections.
Is the TZ300 factory default a similar setting, or it comes in a more bare-bones networking, requiring firewall restrictions to incoming packets to be manually set?
I have an NSA3600 HA appliance that I wish to upgrade to standalone. We're prepared to buy the license and perform the upgrade, but are concerned that this will trigger a restart of the appliance, or worse, a need for reconfiguration. The appliance is in a remote datacenter, so any kind of manual access is costly in time.
Has anyone done this process who can relate their experience?
Hello,
i've followed this procedure https://support.software.dell.com/sonicwall-sonicpoint-series/kb/sw11076 to configure two wlan networks. We have one ssid for corporate and one for guest.
If I plug one sonicpoint directly to the sonicwall, everything is working.
If I plus the sonicwall through a managed hp procurve switch, the guest wlan is not working (no dhcp). The corp network is working (if I'm not tagging it with a vlan).
So I guess I've a switch configuration problem and I can't manage to make it working.
How should I configure the link between the switch and the sonicwall ? Tagged with the 2 vlan corp and guest ?
How should I configure the link between the switch and the sonicpoint ? Untagged or tagged also with the 2 vlan ?
Any help would be much appreciate.
Regards
Gilles
Is there a VPN client for Mac's on the TZ215? I have been coming up empty on my search other then a free one over at Lobotomo that I can't seem to get to work. Unfortunatly their user fourums appear to be down so I can't ask there. What I need for them to work is a working config file. I find it hard to believe that Sonicwall (Dell) doesn't have one but thought I would ask anyway.
Thanks,
Jim
I have a connection to an oracle server that passes through my NSA 3500 firewall.
It goes through a NAT rule and I call the server from behind the NAT.
I've been testing with TNSPING and some times the ping goes OK, but most times, the firewall RECEIVES the ACK packet from the client and DOESN'T FORWARD it.
So I tried setting up a route instead of a NAT through the sonicwall box and got still the same problem.
I think it might be related to DPI, but I'm not sure.
Thank you.
Good afternoon, all!
I suspect I have a problem with a site-to-site VPN when the internet service provider changes. Here's the setup:
There's a VPN between my datacenter and a customer. This VPN terminates on our end in a NSA3600 and on their end in - I don't know.
Also in my datacenter is our primary ISP and a secondary ISP.
In an unscheduled outage, we observed that SSL traffic between our mail server and the customer's mail servers was being rejected. At the time we had other elephants to juggle and weren't able to follow up. We have a service interval coming up and would like to catch this behaviour if possible.
I tried setting up a packet capture between the local and NAT address of my mailserver, and the two addresses for the customer's mailservers. I got nothing but dropped traffic, even though the mail logs show SMTP traffic between them.
I suspect some settings are incorrect, but I don't have much time to experiment. Are there any suggestions anyone might have for capturing this traffic either just before or just after it goes through the VPN?
Thanks to all for looking!

A client accesses a webpage but the owner of the webpage warns them that we use the site too much.
Now I want to setup some monitoring especially for that particular website how much traffic (requests) we sent to them. So when the site-owner says we use it too much, we have some ammunition to show that we either indeed use it more often (and that we know which internal IP caused that) or not.
I have made a special firewall rule and enabled netflow. Unfortunately this doesn't give me the results I need.
Does anyone out here have an idea how this can be achieved?
The client is using a NSA3600 with the latest SonicOS.
Thanks for the answers.
As we follow Dell SonicWALL Security Center's suggesting for blocking old browsers behing Sonicwall NSA from here , we found that our outlook client (2010, 2013 and 2016 ) render HTML email with user-agent IE7, which is blocked on Sonicwall NSA App Control "Microsoft Internet Explorer -- HTTP User-Agent MSIE 7.0". Is it possible to identify it's from Outlook Email Client, or probably IE11 run in compatibility mode ?
Thanks!
I can access something like : http://192.168.1.216:9090/NewSoftHr/login.ns from local network . The server is running Apache Tomcat/7.0.14
but I cannot access it from the internet http://XXX.YYY.33.206:9090/NewSoftHr/login.ns
What I did is the following:
1. I created a service object HT9090 : TCP and port 9090
2. I Created a group service object named HR Portal Services which include both HTTP and HT9090 service objects.
3. I created 2 address objects for the server Private 192.168.1.216 and Public XXX.YYY.33.206
4. I created 3 NAT Polcies Inbound, OutBound and Loopback ( created by wizard)
Source Original | Source Translated | Destination Original | Destination Translated | Service Original | Service Translated | Interface Inbound | Interface Outbound |
Firewalled Subnets | HR Portal Public | HR Portal Public | HR Portal Private | HR Portal Services | Original | Any | Any |
HR Portal Private | HR Portal Public | Any | Original | HR Portal Services | Original | Any | X1 |
Any | Original | HR Portal Public | HR Portal Private | HR Portal Services | Original | Any | Any |
5. I Created an Access rule from WAN To LAN , Source port : Any , Service : HR Portal Services , Source : Any , Destination : Public Server.
with Allow Action.
Would you help me if I am missing something
On a previously working machine, NetExtender won't connect. We can log in, enter one time password, and appears to be connecting, then pops up with "Releasing security functions..." then "Remote Access Service error! (Rebooting might resolve the problem."
Rebooting does not resolve problem. Other machines are connecting OK. Reinstalled NetExtender twice. Internet connectivity is OK. Disabled AV and Windows Firewall....no resolution. I don't see any Windows updates or any other recently installed software.
Windows 10, 64-bit laptop. SSL-VPN 4600 v8.1.0.3-17sv
Any suggestions would be greatly appreciated.
We're having people occasionally have their remote desktop host sessions get dropped.
They're on a VPN between two Sonicwall NSA 3600s, fairly similar configurations.
I noticed when pinging different results with different ping timeout values.
With a ping timeout of 500 ms or 750 ms, failed pings occur frequently.
With a ping timeout of 1000 ms, pings don't fail.
What kinds of things should I look at to ascertain the cause(s) or remedy(ies)??
Ping times are usually in the high 30's, ping TTL is 50.
Is this a latency issue?? TCP timeout issue??
What should be reviewed to see why the dropped RDS host connections??
People on other VPNs to the same SonicWalls don't experience these dropped connections, they only occur within a specific site-to-site VPN...what should be reviewed for possible adjustments??
Thank you, Tom
When I use the SonicWall Global VPN Client on Windows 10, my CPU usage for the tapisrv process increases, even after I exit the VPN client. The only solution is to reboot.
How can this get fixed?
See attached picture of Resource Monitor.
SonicWall Global VPN Client 4.9.14.0427
Windows 10 Version 1607 , OS Build 14393.51
How to replicate. Boot into Windows 10, Start the client and connect to VPN server. Disable the connection and exit the VPN client. Then see that tapisrv is using CPU. See attached picture of Resource Monitor.
Hi guys, I am hoping someone could assist me.
I have multiple zones set up, eg. dmz, students, faculty etc, I have a pretty strict App Rule that is blocking VPN, Remote, Proxy etc access signatures. We do however need access to some of those apps intra-zone, eg. VNC between student and faculty zones. How do I modify the App Rule to only prevent internet bound traffic and not local traffic? I would actually prefer not having any on-firewall intra-zone application filtering as it interferes with things like WDS etc. I have tried using "wan subnets" as the destination but it then matches nothing.
Thanks!
NSA 2600, SonicOS 6.2.5.1-26n
I have a few TZ400 series sonicwalls. I'm trying to look for some traffic in the packet monitor. I set the filter up for Source IP to be the computer in question, but when I start capture, I end up with HUNDREDS of packets with no source or destination IP.
I would think creating a filter on the IP should eliminate anything that does not have that IP address but it doesn't seem to? This makes packet hunting a needle in a haystack! At 50 items per page, I end up with 20 pages and maybe 10 total records actually meet my filter criteria.
Am I doing something wrong? Any help would be extremely appreciated!
Thansks!
I have a web server hosting an api sitting behind a NSA 2400. I followed these instructions (support.software.dell.com/kb/sw7484) to open up the web server to the web. Internally, the web service works perfectly. From outside our network, we occasionally receive 504 errors at random. After tracing with wire shark I found failed requests are not making it to the web server. Sonic wall is logging a 'Web Access Request Dropped" error. I'm not familiar with sonic wall logs. How can I resolve this problem given the log detail below?
I am moving to a city with Google Fiber & I would like to be able to connect my SonicWall directly into their Google Fiber Jack and not have to double NAT my home network behind their router/Google Fiber Network Box.
After doing quite a bit of research I have found it is possible to use your own device, though you have to change some settings to get optimized performance. Essentially according to the tutorials I have found on setting up other Firewalls/Routers I will have to tag the traffic out the WAN with a 802.1q vlan id of 2. I need to know how to do this with my firewall.
Examples of configuring other devices for this can be found here:
www.itnutt.com/.../
& here:

After searching around the knowledge base and SonicWall forums I am not finding useful information for this particular setup. Any help will be appreciated.
We have Office 365 as a service, no Exchange server but use Office 2013 Pro and therefore Outlook 2013 on our computers. I tried to enable DPI-SSL – Client SSL on our NSA 4500 yesterday but Outlook started displaying pop-ups to our users who in-turn inundated me with phone calls and emails, so I disabled it. For example, two pop-ups were for autodiscover-s.outlook.com and pod51045.outlook.com.
I know we are talking about site certificates but email is a big security concern for many organizations so I am being extra cautious about it. I don’t want to add outlook.com to Common Name Exclusions (CNE) because of everything that could come in via email, we definitely want it all checked. If I did add outlook.com to the CNE, would that cause all emails to be bypassed for DPI-SSL because they are coming through Outlook? How many certificates for Outlook are there? Should I have users select View Certificate – Install for anyand all Security Alert ending in outlook.com? We also have users that only have access via web mail outside of our network – will they be affected and, if so, in what way? What would be the best way to handle all of this? I have already used Group Policy in Active Directory to distribute the certificate to all our computers for IE. All of our mobile device users also received the certificate via email so they can install it on their phone, tablet, etc. I added URLs to the CNE list prior to enabling DPI-SSL but I understand we’ll encounter others as users access various sites. I can add the two URLs that popped up to the list but more from Outlook may keep coming up. Is there a reference of URLs (suffixes) that one needs to add to the CNE list specifically for Outlook or other major packages (such as Microsoft Office)?
SonicWall NSA 4500; SonicOS Enhanced 5.9.1.6-5o
Majority of users on our network are Windows 7 Pro SP1 with automatic updates; MS Office Professional Plus 2013; web mail - Office 365 as a service
Sorry, ignore this.
Hi All,
I am attempting to connect to a sonicwall via GVC which works great. I can RDP to a server on that network. The problem is that I have 3 networks connected via site to site vpn and I cannot rdp to servers on the other two networks unless I do it from the original RDP connection. In other words, I can get across the site to site vpn as long as I am doing it from a server located on one of the networks, but not from my laptop connected via GVC.
I am thinking this is some sort of routing issue but I do not know where to start. Since I can access servers across the site to site VPN from the local network, I would think that my laptop, which is just a node off the local network, should also be able to connect. Possibly it is a Global VPN policy issue. At any rate, any help is much appreciated.
Thanks
Dear all,
I just purchase an old Sonicwall TZ170 to have a better control over my home internet but our ISP use only PPPoE connection.
I reset the device to factory default, I upgrade to the latest firmware and configure the WAN using the Wizard. I add the user and password and I try to connect but with no results.
If I plug the WAN cable into the exiting router everything work perfect. Also, I call the ISP and I describe him the problem and he told me that they see the device in the network, but it's unable to receive the IP.
I can do anything? I try with the default MTU1500 and also with MTU 1492 but with no results.
I need an advice if I can use this Sonicwall with PPPoE connection.
Thank you.
Nick
