Multi-WAN HA PPPoE from different ISP



  • Hi!
    I want to make a Multi-WAN PPPoE with High Availability, failover and loadbalancig.
    I have two PPPoE uplinks from different ISP, and two pfSense PC (x64).
    I've heard that CARP can't handle 2 pppoe uplinks. (I don't know if it's true.)
    Is this setup possible? If yes, how?
    Thank you in advance for your help.



  • CARP is designed for a router failing or router interface going down, so the IP addresses will switch to the backup router. The CARP IP on WAN isn't going to work on both ISPs without some sort of SD-WAN arrangement.
