How to dedicate IP traffic through one specified WAN port

Carlsap · May 2019

One specified adress is to be reached from an USG310 WAN2 + DNS queries. All other traffic is routed through WAN1.
Reason for this scenario is to provide one specific license service connection during WAN1 outage.

Hi @Carlsap

You can setup policy route for this scenario:

Source: Server address, Destination: any, NextHop: WAN2

Source: LAN subnet address, Destination: any. NextHop: WAN1

Hi @Carlsap

As your description:

(1) if the client access to specific external server would like to pass through by WAN2.

(2) Other going traffic is pass through by WAN1

Then you can create policy route for this requirement.

(1) Source: any, Destination: External Server IP, NextHop: WAN2, SNAT: outgoing interface.

(2) Source: any, Destination: any, NextHop: WAN1, SNAT: outgoing interface.

Thank you for the suggestion, but I made a mistake in the question.
I ment one external adress is to be reached through the WAN2 and outbound DNS queries must be allowed as well. All other outbound traffic should be routed trough the WAN1.
