I want to write software that communicates to a server on the internet using a non-standard TCP port. I did not expect it from a home wireless router but it seems to me it blocks my outgoing request, or - at the very least - any responses I'm meant to be receiving.
Could it be that it does that? I'd expect it to block incoming connection requests, but will it block outgoing connections? replies on connections initiated from within the network?
Looking at the configuration options on my router (WGR614V9) I can see port forwarding and port triggering options, but I can see a way to simpliy say - please allow two way communications over port xxxx, should I be able to?
I've looked at the manuals of various other routers online and can't see any explicit configuration entry to that effect anywhere, is that generally not possible?
Forgot to add - when I've plugged my laptop to the broadband modem itself (bypassing the wireless router) the request went through ok as did the response, so I am pretty sure the 'problem' lies within the router
