We have a vSZ running with 3 interfaces behind a router.
Now we want to add a 2nd node to this cluster, also with 3 interfaces. This 2nd node is at a remote site and also behind a router. What ports should we forward in order to have te cluster interfaces to communicate?

you need 100 Mbit as minimum speed only for the cluster traffic and a max latency of 9 ms.
if your line does not give you this values, the cluster will never get synchronised.

Completely agree with Harald,
It's a really bad idea, cluster doesn't work over Internet links. Don't even try! Even if you will be able to install it, you are guaranteed to have problems later, as Internet isn't stable enough.
This can be done only if you have 2 locations, which are not actually that remote, but say in the same city and connected by direct fiber link, preferred -- L2. Than cluster will work normally, same way, as when all nodes are located in one server room.
Hope it helps.

Thanks for your input guys.
Suppose we meet the conditions described above, and both nodes are behind NAT routers, what port(s) should be forwarded for the cluster interfaces to connect?

Build a vpn between both networks, that would be the easiest way.
The exact ports are in the vsz documentation.
