CARP, PARP, Multiple WAN subnets and Multiple gateways

[geoff2010]

Hello,
I have a pfsense install which is working great.  We run CARP for failover and havehad no problems… aside for the annoying need for a reboot any time i change something.  Anyway, I ran out of IP addresses and need to assign an additional block to the WAN interface in a totally different subnet.  I have read all the recent posts on here about this particular challenge, and it doesn't seem like it should be too big a challenge to assign them as ProxyARP VIPs.  I guess I won't be able to have automatic failover for these, but oh well.

Anyway - my real question is that I was assigned a different gateway for this IP block.  How would I deal with that using ProxyARP addresses?

Thanks!
Geoff
