Controlling HTTP & SMTP IP flow for 3 NIC's
[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]
A little background first..I run 2 servers, mail and web. The mail
server is down for hardware problems. I'm running both email and web on
one server. The web server has 3 network interfaces 1 for public email,
1 for public web, and 1 for private network. I use 3 cards because the
router I connect to the internet won't recognize multiple IP's for a
single hardware MAC.
The problem is, that my email messages seem to be going out the web
network interface. This is typically not a problem except for the
reverse DNS lookup fails which at least one domain (Comcast.Net) rejects.
My question therefore is, how can I route my sendmail traffic to go out
the correct ethernet interface? I'm sure I'll need to do the same for
the web traffic so web site spoofing alarms are triggered.
I have told sendmail to listen to the correct interfaces, but that
apparently doesn't mean only write to those interfaces. I don't see how
to control this by setting up my routes and I can only really think of
ways to block it in IPtables, not re-route it.
