I will have to check and see if I can access the server via something off the network now!
Any other advice?
I will let you know and mark it solved if it works
Sorry, I had assumed you had a local server connection. Yes, the tcpdump command I mentioned will blow up if you are using an SSH session to it. Why? becuase the tcpdump filter gets a hit, which causes output to the terminal, which causes more tcpdump hits, which causes more output to the terminal, ... For further tests using tcpdump and also via your putty session, try redirecting the tcpdump output to a file, then examine the file after your test accesses from the WAN.
Kevdog: From earlier postings, I think there is no firewall on the server. If that is not true and there is a firewall, then I would definately look there.
Edit: Or change the tcpdump command to exclude 192.168.1.6. Example (where my SSH session is from 192.168.111.101):
Code:
doug@s15:~$ sudo tcpdump -n -nn -tttt -i eth0 not host 192.168.111.101
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes
