Different Interface to difference WAN

Mon May 17, 2021 1:04 pm

Hi All,

I think it sounds stupid, but I just want to double confirm.

Scenario Ether=WAN1 , Ether2=WAN2 , Ether3,4,5=Bridge (VLAN1,VLAN10,VLAN20,VLAN30).

If I want VLAN1 user to use WAN1, and VLAN10,20,30 to use WAN2, is it possible to be done in firewall > NAT?

Chain: scr-nat
Src. address: 172.16.0.0/24 (VLAN1)
Out. Interface: WAN1
Action: masquerade

Chain: scr-nat
Src. address: 172.16.10.0/24, 172.16.20.0/24, 172.16.30.0/24(VLAN10,20,30)
Out. Interface: WAN2
Action: masquerade

So user in VLAN1 wont share the bandwidth with user in VLAN10,20,30.

Is it possible to work?

Thanks.

Ask yourself this question: How does it work out where to route the WAN1/2 outbound traffic in the first place?
Src-nat happens at the very end of the chain, if you look at the packet routing diagram, so obviously a routing decision needs to be made earlier somehow.

Please keep it to one thread, aka the one linked above.

WAN stands for Wide Area Network and this is the network that connects your router to your service provider. The WAN port usually connects to a DSL modem, cable modem or fibre media converter. LAN stands for Local Area Network and this is the network that connects the devices within your home/business to the router.
