NAT Inside Interface to OutSide Interface

Good Evening, I am running 3CX.  My internal network is 172.16.10.0/24, but external is 192.168.0.0/24.  I need to NAT 172.16.10.14/24 port 5001 to 192.168.0.50.  I was able to get 192.168.0.50 active however it was only taking me to my XG for signin vs actually NAT'ing my internal device.  Please help

  • Hi,

    please your firewall rule.

    Your firewall should look like any - internal network -> any - > external network-> service port 5001 -> allow -> log

    You will not need MASQ.

  • I tried that, I had to remove it, these are seperate interfaces, 172.16.10.x is on one interface and and 192.168.0.x is on another

  • Hi,

    I suspect you have not explained your requirements very well.

    The pointing an internal port at the XG external will not achieve anything.

    The rule I suggested LAN, 172 network - WAN - 192 network port 5001 - allow - log will work.

    What you are not saying is where the 3CX is and what connections does it offer ? 3CX from memory is a digital PABX which you appear to be trying to use to provide internet gateway functions?
