Single WAN IP, VoIP vendor requires 1 to 1 NAT, more than just VoIP service needs to pass
I have a FortiGate 60E
OS v6.0.4 build 0231
Single WAN IP address
Multiple services on multiple internal hosts (VoIP + web services) port forwarded currently (and working for the most part)
VoIP (3cx) vendor wishes to enable webRTC
It is not working - 1 way audio
Seems to be NAT issue with webRTC - fortigate IP LAN IP address is being substituted for WAN which 3CX says is the problem
Is there a way to configure my port forwards so that I can allow VoIP webRTC to work, and still have web service port forwards, on a single WAN IP address?
Or is 1 to 1 NAT only way to achieve this type of NAT behaviour on a fortigate?
