How to match a WAN to a DHCP server, then map a WAN 2 to a DHCP server 2, etc.

The three DHCP server are the same, same gateway and pool but with WAN different.

Thank you for your help

Best regard.

Hi,

If you bridge port 8-10 and set up the dhcp server and hotspot on the bridge interface, it should do the trick.

Hi p3rad0x,

I can not make a bridge, because although the DHCP server are the same, they should not communicate.

These are the final three independent networks.

You should try using gateway routing marks - set provider name in the ip route settings. From Mangle, set the source IP to get a specific routing mark (in this case the provider of choice for the DHCP domain). Finally in the Ip Rules, set source IP to lookup the name of the provider as set in the ip route. I’ve done this to isolate multiple networks mapped to different ISP.
I guess this kinda makes you an idea how to set a specific gateway for a specific traffic source or type - https://www.youtube.com/watch?v=47uJZcDn10A

Well if I get correctly what you’re trying to do. The easiest cleanest way is to use VRF.

Map one VRF for each lan/wan pair. This way none can communicate with each other and you’ll get the behavior you want (As in, blue uses blue Internet connection).
