[LARTC] Multiple Internet Interface Issue

Okay, here's the deal, (diagram below)

I currently have 3 NIC's configured in my Linux server. 
   eth0 serving the home network
   eth2 Cable modem to internet
   ppp0 ADSL to internet (through eth1)

Connections can be established from eth0 (192.168.0.0/255) 
                           and from eth2 (24.250.85.128/128).  Because eth2
has the first default route.

However, ppp0 has a problem.
Traffic is received from ppp0 there is no return traffic through that
interface
unless the first default route is directing traffic through ppp0. Meaning
nothing goes out through eth2.

At this point, all I want is for connections able to be successfully
established through both internet interfaces (ppp0, eth2). In its present
state if someone tries to access any services(ping/telnet/ssh/etc.) via the
interface not setup as the default route, the connections timeout.
