I was under the impression i could use nat to NAT port 5080 externally to port 5060 internally to the SBC? I have just changed the ITSP to register on port 5080, and removed my natting on my pfsense box, so it is natting those ports to eachother internally and externally... It wont register, so i will ask my ITSP.
