Some background...
I use a Netcomm modem/router/hub/firewall which runs embedded Linux for my connection to the internet...on my LAN I have one Mandrake 8.1 box and two WinME boxes. The Mandrake box is a simple server running Apache, Postfix and Squid mainly. The Netcomm uses port forwarding on ports 80 & 25 (ONLY) to the Mandrake box. As you may have guessed, I have a problem... 8-) The problem is this: I receive mail and everything else just fine, and I can send small emails (under about 10-15k) just fine, but cannot send anything larger. If I try it will start to send then slow gradually until it comes to a grinding halt and eventually times out. As near as I can determine it's related to this: http://home.uninet.ee/~ragnar/manuals/postfix-19990906-pl02/faq.html#timeout s My knowledge is very limited, but obviously (?) I need to forward ICMP messages to the Mandrake box. My questions: How? What other ports should be forwarded? Thanks... -Ross --- Outgoing mail is certified Virus Free.
