vSZ behind router, add 2nd node to cluster

Hi all,

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?

Hi sureal,

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.

Hi Trevor, that's great to know. Is it supported for all 3 interfaces? It used to be the case that it was only for the AP facing NIC if memory doesnt fail me.
