I have recently moved to BT Business Broadband and I cannot forward any ports.
My setup is:
BT Hub (bridge mode) --> TP Link Archer MR600 --> switch
I have set up port forwarding in the TP Link and it simply doesnt work.
Any gotchas people are familar with?
Much appreciated!
this is a handy site to check open external ports

Also in a command prompt type netstat -ano |find ":your port number" and if it doesn't return an IP then the device you are forwarding to is not listening.
