Setting up a cluster with nodes in two different networks

[NoobProx]

Hallo,
ich würde gerne wissen, wie ich 2 Nodes aus verschiedenen Netzen zu einem Cluster verbinden kann.
Ist dies nur über ein VPN möglich, oder gibt es andere einfachere Alternativen?
Vielen Dank im Voraus für eure Antworten!

Hello,
I would like to know how I can connect 2 nodes from different networks to a cluster.
Is this only possible via a VPN, or are there other simpler alternatives?

Many thanks in advance for your answers!

Did you encounter error messages when you tried?

As far as I know it should work. The limiting factor (network wise) is latency. And multiple physical (not: VLAN'ed) connections are highly recommended to separate a possibly congested line by VM traffic from critical corosync.

So..., a VPN from one location to another is problematic. Not because different IP address ranges (inside the VPN they are in the same network, aren't they?) but because of mentioned latency. DSL @Home is probably a no-go!

(Not mentioned: you can not build a stable cluster with two nodes. You need three, or an independent Quorum Device. That third vote needs connectivity to the survivor when - not:if - the primary connection is dead.)

Disclaimer: I've never tried this!
