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

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

Sounds like your default route on the PC that are directly connected to the
firewall side does not have a route back to your second network on the as400
side.  So the firewall need to know about the 172.22.x.x subnet with a hop
of your as400 on the 172.24.x.x network.

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)

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?
