Hi Eric,

I gave it a second try to find a non-intrusive way to attach a health-monitored def_gw_pool to a "Forwarding (IP)" virtual server. It seems I've found one...

when LB_FAILED {
    if 0 { pool YOUR_GW_POOL } 
}

The LB_FAILED event should't trigger at all (no performance impact). And if the event was somehow getting triggered, then it performs "nothing" (no risk).

In the end it will just turn your LED to green/red depending on the availability of the given pool.

Personal Note: Never say never nor impossible... 😉

Cheers, Kai
