Corosync runs on the IP addresses that you configure in
/etc/corosync/corosync.conf.

Pacemaker requires unique hostnames (as they are retrieved via uname -n) to
function properly.

If they are "internal" or "external" it really doesn't matter for the
cluster stack, that's a human point of view, the machine has no real opinion
in this (e.g.: if you configure IP communication channels properly, then
corosync will use the internal network, but the hostnames will be set to the
"external" hostname as these two are unrelated).
