Hi,
the gateway for the internal port (which is needed to form a valid cluster) should also be memeber of VLAN25.
I cannot configure VLAN-Parameters on the internal port. I only can configure vlan-parameters for the VLAN-Interfaces which are created "onto" the internal port. So, the internal port itself will always send untagged traffic, destined for VLAN1. But we don`t want to have VLAN1 in use.
Here some links, which mayb help you to understand my situation:
Thanks, Christoph
