I have a CUBE configuration that is also acting as an internet gateway. Unfortunately applying a NAT to the interface destroys SIP and the gateway fails. Remove NAT and all is well. This is in a rural community in which they cant really afford multiple devices, so we need to figure out how to best configure the interface so that it can support both internet traffic and SIP traffic. The carrier uses the public IP address to authenticate. We considered using a subinterface but there is not equipment to front end the trunk creation. Is it possible to set a static NAT and bind to a loop back interface for the SIP traffic?
Open to recommendations on how best to make this work!
