If you use 255.255.255.0 then 203.29.98.1 expects that 203.29.98.254 is
within its network, but this is not the case. You must use two subnets with
netmask 255.255.255.127, assign Server 1 (203.29.98.1) as default gateway on
each client and also aktivate IP-forwarding between the two NICs.

If you want to open both subnets, I do not understand why you don't just use
one NIC in server 1. Am I missing something?
