   I have a strange problem.      When I try to connect to a mail server from my linux router it can't connected to port 25.   It seems like only port 25 is affected.
The WAN port is DHCP and the LAN is set static with NAT enabled on outbound.

   However a computer behind my linux router has no trouble connecting to port 25.    It's only when I try to connect from the linux router itself.   I'm using IPTables 1.3.3

   Does anyone have an idea of what is causing this?



some linux dists also compile tcpd/sendmail to work and play together, and this might be the case if your setup has a default deny in the /etc/hosts.deny file, took awhile to figger that out here when working with a new slackware setup and old hosts.xxx files moved from other working setups.

Thanks,
