I have a business partner who has a L2L tunnel setup. They insist that they are properly routing traffic to through the tunnel to an internal FTP server at my site (We also allow them to access some UNIX hosts via Telnet through the tunnel, which works).
At this point we don't have a whole lot of access restrictions as far as ports. Currently we only allow 2 IP addresses from their network to access 2 IP address inside of ours. We are using NAT for our 2 addresses.
When I run a sniffer between the 3030 and the FTP server I never see traffic from their network to our FTP server. Is there a way to log or see what the 3030 is dropping for that tunnel?
