Routing multiple blocks of IP



  • I have 2 Pfsense servers configured in a CARP cluster running for quite a while.

    My ISP originally provided me with this External ip block 67.217.165.193/27
    I needed more IP so they gave me:

    74.209.254.224/27 statically routed to 67.217.165.209 (on my current subnet)

    How do I configure pfsense to use this new ip block and will I still be able to use CARP failover features in this scenario?



  • I had temporary needed this, too…

    • add an IP alias from new network for each firewall and
    • the rest of IPs can be used again as CARP adresses within this network.
