UPnP, Firewalls and Firewalls
January 1, 2008 – 11:57 amAfter the install WHS attempted to configure my router, and this appeared to work initially. Upon further investigation it seemed that WHS was failing to configure the router via UPnP, and I was getting error messages via the WHS console. My Netgear 834GT does support UPnP, but for some reason WHS was failing to forward the required ports. I opted to configure the router manually by forwarding the following ports:
- TCP 80 (required for HTTP)
- TCP 443 (required for HTTPS)
- TCP 4125 (required for Remote Desktop)
All the above ports were forwarded to the Server internal IP (e.g. 192.168.0.2)
Unfortunately, even with these changes there were still problems. It turned out that my ISP (Plusnet) was also providing me with a broadband firewall which was ON by default.
I accessed the advanced options for the ISP firewall and opened the required ports. Remote access to WHS now worked without any problems, although WHS was still displaying warnings in the Router Configuration Details page regarding UPnP, Web Site Connections and Remote Access Connections. As it all now works I’ve not bothered to investigated why WHS thinks there are issues, I assume that WHS is just failing to communicate with my Netgear 834GT router.
