If you ping these systems continually, they may get annoyed at you.
Maybe at least ping the first router on the other side or something. By
default, heartbeat is going to ping them at the standard heartbeat rate.
People unrelated to you are likely to consider pinging them that often
as an unfriendly and anti-social behavior.
Deadping is the dead time for ping nodes. I thought we also had a ping
interval settable separately - but I don't find it in the code... I
guess it was just something I thought about - but we didn't add it. If
you wanted to write such a patch, I'd be interested in seeing it...
I suppose if your two machines have different routes, this will work
from a technical perspective. It's the administrative and political
aspect that worries me more...
