[LARTC] Two routes to Inet no inbound traffic

[LARTC] Two routes to Inet no inbound traffic

[wyonker]

<PRE>I have a question.  I have two dissimilar connections to the internet. 
 I have DSL and Cable Modem.  My domain name is mapped to my 
cable modem connection which is eth0.  My DSL is on eth1.  eth2 
is my internal LAN connection.

When I have both routes up, I don't get any of my inbound traffic 
such as email.  I can still get out to the internet fine.  Of course 
there are two default routes but I didn't think that would be a big 
issue.

I'm running Redhat 7.0 with kernel 2.2.16.

Any ideas?

Use tcpdump or ethereal to find out where your outgoing traffic is going.
Check that the traffic appears on the right interface - 'egress filtering'
by one of your ISPs may be killing 'martian packets' on your DSL or cable
modem.

If that doesn't solve your problem, describe your situation more completely.
IP addresses, netmasks, and how your mail is supposed to arrive.
