Firewall with more than one External interface

Hi all,
i've a question about linux firewall, hope that here is a good place.
Sorry for my english.
My problema is this: i've one box with 4 NIC. Two nic are in INTERNAL
(secure) lan and the other two are in the External (insecure) lans.
The two external have connection with two different router of two
different Internet Service Provider. The two pubblic IP class
naturally are different.
The box works now with all two the providers, and i'm able to make
some NAT between one provider or the other.
The firewall is setup with FirewallBuilder.
Now happened that i MUST reconfigure all, and i start from a clean
FirewallBuilder setup.
So, only the IPTABLES configuration, from FirewallBuilder is change,
non network setup is change.
When i apply my new configuration, i'm able to make NAT only from one
of the two internet service provider (and the pubblic IP from this).
Naturally, the one that is specified like GATEWAY in /etc/sysconfig/
network file (Fedora Core 4). So, what i missed? What i forget? Where
i can specify that all two the provider can be a GATEWAY depending
from were the request arrives? ... why with the old FirewallBuilder
configuration works (naturally not maked by me) and now not works?
Thanks all.
Mauro.
