Sounds like a routing issue on your AS400.

Can you ping the NAT router from your AS/400? I suspect not.  I don't think
your AS/400 can see the IP address 63.64.65.66 (as per your example).  Your
AS/400 is on the 10.10.10.x subnet (as per your example).

Your first job is going to be to get your AS/400 to successfully ping you NAT
router.  After you can do that, things should work fine.

This is a cross-post.  I've posted it in a couple of other places, mostly
because I am completely baffled and have no idea where to turn.

Here's the issue:

<SNIP>

And regardless of the WHY, this is how it works. So, rather than try to
figure it out, I decided to go the next step. And that next step is to try
and figure out why the AS/400 wasn't responding. And pure and simple, the
AS/400 was ignoring those packets. Here's the trace:

10.10.10.104 --> 63.64.65.66 (initial request)
63.64.65.66 --> 10.10.10.103 (request forwarded to AS/400)
(delay)
10.10.10.104 --> 63.64.65.66 (initial request)
63.64.65.66 --> 10.10.10.103 (request forwarded to AS/400)
(delay)

That goes on until the browser times out. Remember, communications work fine
on the intranet, and if I watch the communications, it's fine:

10.10.10.104 --> 10.10.10.102 (request)
10.10.10.102 --> 10.10.10.104 (response)

So, the issue seems to be that the AS/400 doesn't want to communicate with
the external address. Now, where in the world is this configured? Due to a
different problem (which I'll outline when I get a chance), I did a
RMVTCPTBL TBL(*ALL), so that should have gotten rid of any latent IP
filtering. So where else is IP filtering defined? In the HTTP configuration?
In the line description? WHERE??!?!?!?

<sigh>

Thanks a million for listening to the frustrations of a beaten man... <wry
grin>.
