In order to route properly, the router must be between two DIFFERENT
subnets. In your case, you are using server2 to route between NIC1 and NIC2,
but they are on the same subnet, so it will not route. You need to either
put them all into the same network, with just one NIC in server2 and all
clients on the same net with current netmask of 255.255.255.0, or split them
into smaller subnets. If you split it in half, assign the first net IP's
203.29.98.0-127 with netmask of 255.255.255.128, and the second net IP's
203.29.98.128-255 netmask 255.255.255.128 as well. Keep in mind on each
subnet the first and last IP's are not usable, in example above the second
net cannot use IP's 203.29.98.128 or .255
