HI,
I have been working with a sonicwall NSA 220 and have been able to open ports. But for some reason Once I go through the process of opening ports some are still showing as closed when i do port scans. I do not know why this is happening or what the issue maybe. It does not make sense that some ports i am able to open and others are not. I have tried and retried with no luck. Please help. I am running firmware 5.9.1.1.
