I am getting blocked here, from what I can tell its my linux-based pseudo-firewall, as I can do this from my web server which is directly connected to the DSL Router.
I have a Debian Sarge box running Squid/SquidGuard on top of IPTables. The only rules in IPTables are in the nat prerouting and postrouting to bring incoming traffic through to our email server, and take outgoing traffic through the Squid cache transparently.
I have added two rules to the top of the prerouting/postrouting tables to explicitly RETURN any packets to/from my IP address but no joy - any ideas?
Ta,
Jim
