MutliWan on the same subnet of my ISP's DHCP.

[BenGonGon]

Hello,
I want to know if it possible to have multiple WAN on the same subnet provided by my ISP's DHCP?
I have made a shema explaining more pf1.png
Best regards

I don't think that'll work.
Ask for a routed subnet from your isp, if you need more ip's

My provider can not give me a routed netwrork, only many IP by DHCP.

Can you explain me more, please, why you tell :

I don't think that'll work.

because you have identical gateways for multiple interfaces … this is a bit of an issue.

search for terms like "multi-wan same isp" / "multi-wan identical gateway" posts
