How would you go about this - 2 separate nets 1 router

Wed Dec 01, 2021 6:00 pm

Hello

I have a CCR 1009-8G on which I want to achieve the following config.

2 WAN connections - WAN1 to ETH1, WAN2 to ETH8
2 LAN connections - say LAN1 to ETH2 and LAN2 to ETH7

Each LAN independent (with NAT and unroutable address space - say 192.168.100.0/24 and 192.168.200.0/24) - LAN1 access internet via WAN1 and LAN2 access internet via WAN2.

Inter network routing (ie LAN1 <-> LAN2 open)

WAN2 is failover in case WAN1 is not working and WAN1 is failover in case WAN2 is not working.

Is the feasible (I’m pretty sure it is…) and how would you go about it ?

Any suggestion / pointer most welcome !

Very feasible, the only question I have is why are the two VLANS 'open' to each other.
Why not just have one LAN then?

Ok... what woud be your approach to this ?

Fair question question - we want to be able to filter between the two or even to split (obviously loosing the redudency)

Okay so if you want to filter between them then that makes sense.
So why not close them as default and then only open the traffic you want to permit.

Basically if you have a well defined set of requirements we can proceed.
If you dont know them yet the discussion is theoretical.
