Subject: prerouting and postrouting + clamav + clamsmtpd
Date: Sat, 19 Feb 2005 14:54:34 +0200 [thread overview]
Message-ID: <12848a3b050219045423ee8992@mail.gmail.com> (raw)
My network design looks like this:
WIN1
WIN2 - GW1 - MAIL SERVER - GW2
WIN3
GW1 iptable rules:
PREROUTING
REDIRECT tcp -- eth0:1/24 MAIL_SERVER tcp dpt:smtp redir ports 10025
POSTROUTING
SNAT all -- eth0:1/24 anywhere to:eth0
WIN are on the internal network, GW1 does SNAT. I've had a lot of
virii problems on the internal network but MAIL SERVER logs show the
GW1 ip. I installed clamav+clamsmtpd and added the PREROUTING rule.
The problem is I don't get connections on localhost:10025. I can't
access the internal network (WIN) to telnet and check why. Does the
current firewall configuration have any flaw? I added the PREROUTING
rule to pass any traffic to the MAIL_SERVER through clamsmtpd for
scanning.
