Multiple Internet facing Nics - Gateway issue

[Doug Coats <dcoatshca@xxxxxxxxx>]

I have a server with 4 nics.  Two are using different internet connections, both with static IP's, and two are connected to our private network.

 

The two internet facing nics seem to be battling over the gateway designation.  Which ever I designate as the gateway the other stops responding to incoming traffic.  I need both to listen to inbound traffic.  One for our main web page and the other for another web server.  I found some information of Iproute2 but that did not seem to solve my issues.

 

Here are the config files:

 

ifcfg-eth2

DEVICE=eth2
BOOTPROTO=static
HWADDR=00:24:E8:52:92:8E
>IPADDR=xx.yy.51.45
NETMASK=255.255.255.252
GATEWAY=xx.yy.51.46

 

ifcfg-eth3

DEVICE=eth3
BOOTPROTO=static
HWADDR=00:24:E8:52:92:90
>IPADDR=aa.bb.166.2
NETMASK=255.255.255.224
GATEWAY=aa.bb.166.1

 

network

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=heritage01
GATEWAY=xx.yy.51.46

GATEWAYDEV=eth2

rt_tables

#
# reserved values

254     main
253     default

iproute2 routes

ip route add xx.yy.51.44/30 dev eth2 src xx.yy.51.46 table Cable
ip route add default via xx.yy.51.46
ip route add xx.yy.51.44/30 dev eth2 src xx.yy.51.46
ip route add default via xx.yy.51.46
ip rule add from xx.yy.51.46 table Cable

ip route add aa.bb.166.0/27 dev eth3 src aa.bb.165.2 table T1
ip route add default via aa.bb.166.1
ip route add aa.bb.166.0/27 dev eth3 src aa.bb.166.2
ip rule add from aa.bb.166.2 table T1

ip route flush cache

Other people seem to be using this configuration successfully but I seem to be missing something important.

 

Any help is greatly appreciated!!!!!!!  Thanks!
