Hi, I'm trying to help a friend who runs a sonic wall firewall.
It's been configured to route RDP/RDC to two seperate PC's depending on the port passed in. To hit computer A you use IP xxx.yyy.zzz.1:6000, to hit computer by you use IP xxx.yyy.zzz.1:7000. Everything was working fine until my friend hired a half-baked "network guy" to add an FTP hole, and suddenly one of the RDC forwards isn't working.
The RDC PC on port 7000 in question works fine inside the network when using the local ip:7000 (so, we've isolated it to the sonic wall). Working through the sonic wall settings, everything seems fine (nat translation, access list, etc). PC A and B both have similar settings, only with unique destination IP addresses that point to PC A and B respectively. I just don't get it!
I think something is overriding and blocking this one IP, any suggestions where I can look?
