Can you ask the ISP to accept ICMP on your premises router from your
firewalls perhaps?  It shouldn't be a big deal to adjust the filters as
such.

Subject: [gb-users] HA Beacons

Does anyone have any recommendations/best practices regarding choice of
HA beacons?

My upstream ISP filters all ICMP to their own routers/servers, so I
can't use anything of theirs (eg my default gateway would be a logical
choice), and clearly, if I just use the other GB in the HA pair, then if
that goes down, so does the good one (since it gets no beacon responses,
so demotes itself to the init state).

So, where can I use as a beacon that's i) polite to ping twice a second,
and ii) reliable?
