Port Forwarding SharePoint Server behind router and 2 adsl

by triangular_bkk / March 27, 2008 5:41 AM PDT

I think what I'm doing should be pretty simple but I'm not sure why its not working.

We have a Linksys RV016 router receiving 2 separate dynamic IP connections on WAN1 (Linksys adsl modem) and WAN2 (Billion wireless adsl router). We also have a dynamic DNS service subscribed to from DynDNS.

Currently, all three the RV016 and both adsl modems are configured to report the public IP to the DDNS service. I'm not sure if ONLY the RV016 should be doing this, or only ONE of the two modems, or if it doesn't mattter.

We have a SHarepoint Server running behind the RV016 that I want to make available from outside, by Internet users.

In the RV016, I've enabled the DDNS service, and forwarded ports 80, 444 and the specific port that our Sharepoint Site is running answering on. I've forwarded these to the static IP address that is assigned to our Sharepoint Server. I've set the Access Rules to ALLOW these connections from any interface, always.

With the RV016 Firewall on or off, hitting the DDNS name always times out, but I know the DDNS service is working because the login information resolves and updates in the RV016 admin, and pinging the name resolves to the same IP address as our reported public IP address.

What else must I do on the RV016, or what should I be doing on either or both of the dsl modems? I have disconnected one, and then alternatively the other adsl router/modems so that we're only receiving one internet connection in trying to eliminate problems, but nothing seems to work.

Please help me do my job up here. I appreciate any feedback from anyone.

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
