The only way I can think of to avoid having to have separate external IP
addresses would be to require a different port number for each subdomain.
This is assuming that the router can handle sending stuff to different port
numbers on the same external IP address to different internal addresses.  If
it can't, you can throw a server between the router and the AS/400 that can
handle it.

The downside is, of course, that all of the subdomains except one is going
to have a non-standard port number, requiring the users to specify the
proper port number in the browser.  If they don't, they will get the
information from the wrong subdomain.
