<div>I can't see any reason why it shouldn't work with a routed
address (provided of course that your router/firewall passes
traffic on the correct TCP ports) since it's just sending IP
packets- it doesn't matter how they make the trip, just that
they do. Performance might be questionable depending on the
speed of the link. The danger of split brain would be severe-
you'd need good fencing, as everyone always says! Personally I
prefer to have the DR site have a regular snapshot of the data
rather than a live copy in case of corrupted data being
written to all your copies and then having to recover from
backup, but it depends entirely on your application.</div>

+1. Only other thing to add here is you might also want to look at
drbd-proxy depending on the size of the replication link<br>
and the rate of data change.<br>

<p class="MsoNormal">I hope this is not a completely
dumb question, I have a 3 way replication cluster
setup and it is running well no problems. I now wish
to move the 3<sup>rd</sup> node to a datacentre for
DR. can I use a routed address in the drbd resource
conf file as the IP address on the 3<sup>rd</sup> node
or do the addresses have to be on the same subnet.</p>
