      Hi,

      Lots of posts on here around this topic, but all fairly old, or not quite this use case, so wonder if anyone can help.

      We're getting a new BTnet lease wires only lease line installed two two ends of our campus, in failover mode. BT require us to use BGP to advertise our block of /29 IPv4 addresses on both lines, to provide a main/backup scenario.

      Easy, one line into each PFsense box, CARP on the LAN subnets. Done. But what If I want to achieve a single CARP public IP, no matter which BT Lease Line I'm using? Is that even possible, given I have to be running BGP on both routers, and can't mix that outgoing BGP traffic...?

      TIA
      George
