I am attempting to put 3 network cards in one box, running centos 64 5.4

network cards are forcedeth (motherboard), e1000e and r8169.

I have ifcfg-eth0, ifcfg-eth1 and ifcfg-eth2 all configured up.
All looks fine.

eth0 is my internal network (forcedeth)
eth1 is Cable modem
eth2 is T1 data

Once I connect the three networks and try to ping something all I can 
ping is internal network machines.
Cant ping anything on eth1 or eth2.
the route -n looks fine. the correct IP listest on left points to the 
correct ethX on the right.
the default route is using eth2 at the moment.

Is there something "special" about setting up 3 network cards that may help?
What  should I look into?
