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)
