2Talk Port forwarding on new platform

Hi, I look after a couple of clients who are on 2Talk, on the old management platform under "Line Manager" you could manage port forwards to forward through the CG-NAT.

Since moving to the new platform the port forwards I had in place have been retained, but I cannot find where to manage them. Any Ideas?? Its probably staring me in the face............ but :(

Ta in advance

Cyril
