Phone System behind pfsense

  • Hello,

    I am struggling with the in/outbound NAT of our Phone System:

    My situation:

    We have multiple WAN connections (/29) and I want to use the mobile client on a specific external IP address (

    What I did:

    1. entered inbound NAT/Port Forward rules from to (Phone System) for the different ports (5060 etc.)
    2. entered a Outbound NAT rule from to any, using the corresponding WAN interface
    3. entered a FW Rule from to any, using the right gateway.
    4. System advanced/Firewall is set to:
    • NAT reflec. mode: Pure NAT
    • Enable NAT Reflection for 1:1 NAT - checked
    • Enable automatic outbound NAT for Reflection - checked

    testing the external IP, works fine, its
    I tried to get a remote connection using a extra network. It fails, i can see the connection from external, but its does not return any packets: CLOSED:SYN_SENT 4 / 0 208 B / 0 B

    any ideas or suggestions?

    Best regards
