CARP private WAN spoofed MAC
-
I have a somewhat unorthodox WAN CARP setup:
- WAN interface MAC address is spoofed to be identical on both machines
- WAN interface IP is in a private range
- WAN interface gateway is the public gateway
- WAN CARP IP is the public IP
This setup works wonderfully, but now I have the problem where only one machine has internet connection at a time, since of course the default gateway can only be reached by one of them.
To solve this I thought of configuring another gateway with the private WAN IP of the other pfSense, but this gateway is also showing up as offline. I suspect this is because the mac address being the same messes up the routing, so the machines are not even able to ping each other, only themselves.Is there any way to set this up in such a way that I have internet connection on both?
