I am trying to keep my security exposure to a minimum. I think it needs both ports but have heard it only needs 443? I have a NETGEAR WNDR3700 router that allows Port Forwarding, so have set these up manually and TCP to the server address: 192.168.1.254,
also fixed manually. I tried uPnP also and it set up and opened these ports. Thanks... trying to keep the bad guys out.
PS Is there a write up on security gotchas on WHS11 anywhere?
[edit] I have a copy of WHS Unleashed v3 and it says you need TCP on 443 (SSL) and 4125 (RDP).
