Without more details about your configuration, I'll say Policy Based Routing should be able to handle this.

Could you tell me a sk where I can see an example since I tried but it didn't work. I appreciate your collaboration

Hi Leonard,

Probably best to start with sk100500.

Let us know if you have any more questions.

The sk was helpful but I have a problem when I try to reach a different vlan does not work. Any suggestions to solve this problem

Whilst you can use a Source Based Route to default out the Second WAN link you will then need to put into place in the PBR routing for when want to connect to other VLANs within the Company, otherwise will end up going out over the Second WAN link.

If you want inbound traffic on a vlan interface to be forwarded on a specific wan interface, you can configure a PBR rule with the vlan interface as iif and the default route in the associated PBR route table with the nexthop of the wan interface.

As stated before, PBR with source based routing + "Hide behind gateway" NAT settings for the desired prefix should do the trick.

If you cannot make it work please post traffic flow captures from fw monitor so we can see if the traffic is leaving the right interface and if it's coming back 🙂
