RE: Need TCP-IP guru advice - 2 networks, 1 firewall -- MIDRANGE-L

Responding to 2 previous messages;

Chris,

No, I can't ping any devices across the two networks, although at one time in the past I could. Don't know what changed. The AS/400 has a default route of the firewall address (172.24.1.10)

Sound like it might be a firewall configuration problem.  Can you ping any
devices across the two networks?  Does your AS400 have a default route of
your Firewall?

James,

The hosts on the 172.22.***.*** network are all pointing to the AS/400 (172.22.1.1) as their default route, and the AS/400 has a default of the firewall device (172.24.1.10).

Will the virtual ethernet on the AS/400 allow me to connect the two networks? What else can I check?

The hosts on the network that the firewall is *not* on need to have the
default route pointing to the AS/400. IOW, if the firewall machine is
also the AS/400's default route, then all the hosts that must go through
the AS/400 to get to the firewall must have the AS/400 as their default
route.

Simon,

Thanks for your reply.

I checked, and the datagram forwarding is alreadty set on.  I still can't
ping the firewall from a PC on the other network.  Now what?
