Web app visible from "Outside World"

Dear All,

We have developed a (very) small application using CGIDEV2 and we would like to make it visible from the "Outside World", but unfortunately, it is not working too well at the moment. It works very well from within, but when we try to access it from outside our network, we get a the "Page Cannot be displayed" message.

Since we started on this as a proof of concept, we've kept the setup to a bare minimum : 1 iSeries 800 at V5R3, 2 PCs running XP SP2, 1 SMC router and 1 ADSL connexion.

We use the DHCP server embedded in the SMC router to allocate IP addresses to the PCs (192.168.2.2 & 198.168.2.3). The IP address for the 400 is 192.168.2.1. NAT is enabled on the router as well as the firewall. Everybody can see (ping) everybody and it is working fine.

We've followed SMC's advice in terms of port forwarding and we expected to be able to reach the 400 when trying to get to it from the outside using the Public IP allocated by our ISP. But it just doesn't work... We contacted them again and they checked and validated our setup. We also contacted our ISP, just in case they would prevent us to run a webserver, but that wasn't the case.

I am not sure what we are missing here, but we just can't get it to work. So we would welcome any advice and tips on how to resolve this situation...

Many thanks,

G4
