Hi there,
We've just had BT Broadband installed into the office, and are now trying to setup a VNC server to allow remote administration from my home computer.
Thus far, my efforts are hitting an unknown brick wall somewhere.
VNC server is installed and running on the system, another local computer can access it fine using the LAN IP. The Business Hub has the appropriate port forward created onto the correct computer. Trying to connect via the internet IP fails due to timeout, and the port is showing in a scan as unresponsive/stealth. Eventually I made this particular computer the DMZ... this still results in the port being similarly unavailable, with connections timing out. Disabled all available firewall options... same. Used both the prewritten and manually created VNC rules, forwarding port 5900... nothing.
The LAN computer can connect without issues throughout this process. We verified the internet IP address repeatedly, it is correct.
BT have assured me that they do not operate any filtering software that may be blocking the inbound connections, however I cannot think of anything else that may be stopping this. The support team indicated that they are not trained for these problems, and that further tailored support comes at an additional cost.
So... I'm just about defeated. Unless BT themselves are blocking this, I can't think of anything else.
Any suggestions?

The firewall log on the router should at least confirm if the port is being passed through the router or not. If you go to http://www.ping.eu/port-chk/ and enter your static IP with port 5900 and hit go a few times, that will ensure the log is populated. Next access the router GUI and go to Settings> Logs> Firewall Log and scroll to the bottom for the latest entries. Look for dport=5900, it should say either inbound session stopped, or session matches user pinhole, packet passed. If it says packet passed, then we know the router is at least actioning the rule and allowing the ports through.
