Multi-wan with failover … how correctly setup with diffirent subnet

[n1tr0666]

Hello,

I'm want setup two pfsense in cluster for failover with two ISP for dual WAN.

Already configured my two pfsense with syncro and this part work great.

But how setup CARP for WAN1 and WAN2 interface and CARP WAN VIP  ????

I have 3 real address available from my ISP by WAN… but not continous IP :-(

My setup is :

PFSENSE1 - Master
WAN1 IP : 24.122.42.83
WAN2 IP : 24.122.40.14
VIP WAN : 24.122.42.56

PFSENSE2 - Slave
WAN1 IP : 24.122.51.3
WAN2 IP : 24.122.52.91
VIP WAN : 24.122.28.244

And once my CARP configured... what external WAN IP will appear on site like "Whatismyip" ??
If i'm need to forward port 80 for webserver, which IP configure to my DNS records ????

Thx
