I'm not totally clear about your diagram. It looks like you're showing PCs on both sides of your firewall. Does that mean you have _3_ subnets? I mean, sure, the firewall has two sides, but what's the third subnet set as?

Anyway, two other questions... Was the same physical network working fine before V5 on the AS/400? If upgrading OS/400 started the trouble, then you can probably ignore routes on your various PCs or the firewall. Those should all already be set. Maybe the firewall has changed, but start at the AS/400.

Now, have you tried traceroutes from various PCs to the points you want them to reach? Just see where it tells you that routes are actually leading. Go to PCs on each segment and traceroute to PCs on the other segments. Problem configuration points should be obvious.

I seem to remember at V4R5 that I was able to set data gram forwarding by line, and able to use the AS/400 as a passive router. I have lost that ability, though I don't know how or why.

Topology looks something like this:

----------------- | | | AS/400 | TR Card 1 (172.24.1.1) --> PC's --> Firewall (172.24.1.10) --> More PCs | | | | TR card 2 (172.22.1.1) -------> PC's (172.22.***.***) ------------------
