Good Afternoon everyone,

I have recently set up port forwarding on my Sky Netgear DG934 router to forward to a server on my internal network. I have set up standard HTML, SSH, and a custom service for a Tomcat server.

Now, all seems to be working hunky dory for a couple of hours and then I am unable to connect to any of the services. All requests simply time out. I know that the server machine is still up and running and serving requests internally so I can only conclude that the router is not forwarding traffic on the configured ports.

It is like the router's port forwarding service goes to sleep. Has anybody experienced this or has any suggestions for how to fix it?

Many thanks in advance.
