Hmm, this may be a dumb answer but you wouldn't be the first one.
Are you sure you haven't forgotten to enable routing?
echo 1 > /proc/sys/net/ipv4/ip_forward
Also check your access-lists. I've stumbled on that one way too many
times :)

Subject: Routing with two internet gateways
I am having a tough time with a RH6.2 system's routing tables. We have 2
gateways to the internet, and I am only defining one default route.
I am dealing with 3 networks, ISP1, ISP2, and a private network.
On a RH7 machine, using the ISP1 gateway, I can telnet in from outside
to either ip address and be just fine. On the RH6.2 machine, ISP2 is the
default gw, and I don't get any response pinging or trying to telnet to
it's card on ISP1's network.
Here are the routing tables:
7.0box:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
63.230.15.176 0.0.0.0 255.255.255.248 U 0 0 0
eth2
207.224.221.0 0.0.0.0 255.255.255.0 U 0 0 0
eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0
eth1
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0
lo
0.0.0.0 207.224.221.52 0.0.0.0 UG 0 0 0
eth0
6.2 box
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
63.230.15.176 0.0.0.0 255.255.255.248 U 0 0 0

eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0
eth1
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0
lo
0.0.0.0 63.230.15.182 0.0.0.0 UG 0 0 0
eth2
Any ideas? Thanks in advance for your attention to this.
