Done, set a route on 50.1 to 5.0 (test environ is a linksys BEFSR41, live will be Symantec/Raptor fw).

Ok, edited the value of net.ipv4.ip_forward to true. Please note, when I execute a network restart I see the following...
Shutting down interface eth0: [ OK ] Shutting down interface eth1: [ OK ] Shutting down loopback interface: [ OK ] Disabling IPv4 packet forwarding: [ OK ]
I'm not sure where the IPv4 packet forwarding dissable is comming from.

Edited eth1 with gateway blank.

Added.

******** I've turned off the fw to test the routing.
Ok, I can ping from the firewall both ways, machine from one subnet to the other, and vice versa.
I can access my internal web server just fine. I get dns results from internal dns server etc.... so I'm bridging the subnets now.
I however, CAN NOT get out of my 50.x subnet to the internet from the firewall, and from the machine at 5.3.
[root@choke root]# ping www.groklaw.net connect: Network is unreachable
Also, where are the default routes, etc.. stored in RH/FC1? When I first boot, I've got some crazy routes from playing around before....
btw, here is my routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.20.5.0 * 255.255.255.0 U 0 0 0 eth1
192.168.5.0 * 255.255.255.0 U 0 0 0 eth1
192.168.50.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
[root@choke root]#
Dunno what hte 169.254 is, or where its comming from.
My route on the bastion fw (50.1) appears to be ok.
All most there! Thanks!
