Problem: Our client machine witch is on the same network as the VIP can not
get to any services. Machines from other networks CAN get to VIP services.
We get a SYNC_RECV when we do a ipvsadm -l -c when a machine from out
198.144.160.x network attemtps to connect to 198.144.160.59...

Our LVS Server config is as follows.
LVS is a PIII 750, 256 megs of ram running Linux RH 7.1 with Kernel 2.4.4
IPTables v1.2.2
LVS 0.8.0
Running in LVS-NAT mode and using iptables as a Firewall also.
4 Network Cards (We'll be dealing with only 2 of them)
