We have setup a pfsense in my company with redundant internet connections and have Gateway failover configured.
We would like to setup another PFsense as a HA node but not sure what the best route is.
Current Setup.
Main Pfsense
WAN1: Main ISP 1.2.3.4
LAN: 192.168.1.1
WAN2: Secondary ISP: 4.5.6.7
I have read on several articles that this setup requires multiple WAN IP per ISP.
We only have available IPs on WAN1 but WAN2 ISP only provides 1 static.
Any suggestions would be appreciated.
