Two external ip to same internal service

Hello to everybody

I have an UTM 9 with 4 network interfaces: 1 for internal LAN, 1 for DMZ, and two WAN for two different service providers.

I want to publish a service that resides in DMZ on the two external lan; I used DNAT but it works only for the external line that is configured as default GW.

Ex of DNAT:

On ExtWAN1 IP 10.10.10.2:80->DMZ IP 172.31.1.100:80

On ExtWAN2 IP 20.10.30.2:80 ->DMZ IP 172.31.1.100:80

 

Is it possible?
Thanks

A.

  • Hello Adriano,

    If you want to use two WAN Interfaces to the internet, both should have the default gateway set. This activates the "Uplink balancing" and "Multipath Rules" in the interface section.

    Then DNAT should work as expected.

     

    Good Luck!
