Connecting AS/400 to Linksys router

I've had this running with a Linksys router and a 9404-F10 (V3R2) for a
few months.
Here's ONE way to do it.
Assuming the usual default settings for the Linksys (in my example the
Linksys is 192.168.1.1) pick an IP address for the 400 (let's say
192.168.1.10) with subnet 255.255.255.0.
Set the Linksys DHCP to start assigning addresses at 192.168.1.100 (I set
it to 50 DHCP users) so DHCP won't give out this address.
In Advanced settings, open the ports you want to use to the 400 under
Forwarding.  I opened up ports 23 (Telnet), 397 (AnyNet), 8470 (for Client
Access - Central server) and 8476 (again for Client Access - signon
server).  (If you had a release that could handle SSL you would also want
port 992 - Secure Telnet).  If you are going to use PC5250 you could
configure the connection (under OpsNav) to use the default  ports
(Properties/Connection/Where to lookup remote ports) - else you will also
have to open the Server Mapper port 449.  Forward all these ports to the
400 (in this example, 192.168.1.10).
Set a Default Route on your 400 pointing to the Linksys (192.168.1.1).
If you wanted to find your system by name instead of the external IP
address for your Linksys box you could register a name with a Dynamic DNS
service like dyndns.org
