Hello everyone and thank you in advance for any help forthcoming. This is my fist post so I will try to be as concise as possible.
We ran out of public IP addresses in the range assigned to the WAN. Our ISP gave us another /29 Subnet. I ran through the steps out lined here to no avail.
I used a new interface and a new zone on the LAN side to keep the new traffic separate.
Troubleshooting packet handling revealed that the new Zone on the LAN side is not able to reach the WAN. All packets between the two are dropped. Currently I am streaming a series of ping requests for an internet site (8.8.8.8) to generate traffic from the new Zone for analysis.
Ethernet Header
Ether Type: ARP(0x806), Src=[--], Dst=[ff:ff:ff:ff:ff:ff]
ARP Packet:
ARP TYPE: ARP Request
Sender MAC Address: --
Sender IP Address: x.x.20.3
Target MAC Address: --
Target IP Address: x.x.37.26
Value:[0]
DROPPED, Drop Code: 20, Module Id: 47
Ethernet Header
Ether Type: IP(0x800), Src=[--], Dst=[ff:ff:ff:ff:ff:ff]
IP Packet Header
IP Type: UDP(0x11), Src=[x.x.20.3], Dst=[x.x.20.255]
UDP Packet Header
Src=[137], Dst=[137], Checksum=0x6955, Message Length=58 bytes
Application Header
NETBIOS Ns:
Value:[1]
DROPPED, Drop Code: 49, Module Id: 26
Needless to say all pings fail, the only address that responds is the address assigned to the new Zones interface. x.x.20.1.
Other than the new Zone we have LAN(static), WAN(static), and DMZ(transparent mode) active.
Let me know if you need more information, I'm not entirely sure where to start and didn't want to overload this post.
Thanks again and looking forward to your response!
