PF How to add to Load Balance FreeBSD router itself ?

Hi , i have FreeBSD router with 2 WAN and 1 LAN

igb0 >> Modem0 > Default GW
igb1 >> Modem1

in default my usual load balancing system like this:

pass in log (all) quick on igb2 route-to { (igb0, (igb1 } round-robin inet all flags S/SA keep state label "lb"

this configuration i can't access to router when default GW down
i am trying to add my FreeBSD router itself to load balancing system to access it using SSH etc. When default GW state of being down is this possible?
