Your description is a little confusing. For example, I don't understand why you have to set up eth1 on server B with 192.168.1.2 when you have it already set up with 192.168.1.4.

Anyway, I would make sure that routing between network interfaces is disabled both in server A and server B. Besides solving your specific problem, this will plug a security hole in your implementation, as if server A and server B permit routing someone that enters thru your DMZ will be able to access your internal network.

I understand also that the only default route you need in both server A and server B is to 192.168.1.200, since eth0 of both servers are directly connected to Pix Firewall.

To change the forwarding policy, do the follwing:

1) vi /etc/sysconfig/network;
2) change the "FORWARD_IPV4" parameter to "no";
3) save the file and issue a "service network restart &". The "&" is important as it will allow you to reconnect automagically after the network configuration is reloaded.
