CARP on C class that routes to my WAN IP

  • Hi,
    i got a C/24 class that is routed from internet to my WAN IP. My WAN IP is on another segment (/29), other than that routed C/24 class. I want to be able to use IPs from that C class for DNAT (clustered) so i wanted to add CARP IP for it, but it won't allow me 'cause:

    "Sorry, we could not locate an interface with a matching subnet for C/24. Please add an ip in this subnet on a real interface."

    If there a way to add another network class to WAN interface or another IP/24, so i could then add CARP IPs from it?

    Any ideas would be highly appreciated.

  • Have to bump my topic up, 'cause i answered so many others. :-)

  • It turned out i didn't have to split my C/24 and could use IPs from it for S/DNAT on multiple other interfaces.

  • FWIW, there is some discussion of this here:,7039.0.html
