FreeBSD 4.0 server outside firewall POP3 problem

FreeBSD 4.0 server outside firewall POP3 problem

Post by Jiawei Y » Tue, 09 May 2000 04:00:00


I am currently running a FreeBSD server and a firewall as follows Freebsd my firewall

The problem now is that no machine in my firewall can ping or telnet to 250
except the firewall box itself. And when I installed the pop3d on 250, no
one could get their mail from 250 inside the firewall. I assume there is
something wrong with my FreeBSD setting, because telnet from inside the
firewall to other hosts are available (and ping too).

Could anyone suggest what I should be looking into?

1. web server connection problem from outside firewall

I have a BEFW11S4 - EtherFast Wireless AP + Cable/DSL Router w/ 4-Port
Switch Notes  that I use among other thing as an hardware firewall. I
forward ssh and http port request to my linux box. ssh requests works but
http requests do not seem to be working. I can only view pages from my web
server from inside my firewall but not from outside. Even when I set the
linux box as a DMZ host, all the open ports respond except http port that do
not process request. Anyone has encounter such problem ?
