Clients can connect to Uniprint 8.1 services using the virtual server name or IP.
Clustered services that initiate outward connections will use the IP address of the active node as their source address, and not the virtual IP assigned to the cluster group. Any firewalls that need to be configured (e.g. client firewalls allowing Cost Acceptance messages) will need to allow traffic from any of the individual nodes.
This is a known limitation of the current design, and is being reviewed for possible inclusion in a future release.
