Multi-homed hosts are the norm for Enforce (back-up and LAN connection). Occasionally, Vontu has problems with the detection servers binding to the wrong addresses (not the LAN NIC). You should only check one NIC on the Enforce side.
To allow the Monitor to communicate to the Manager, the following properties files must be changed (Note: <IP> is the IP address that you want to bind on):
On the Manager:
\Vontu\Protect\config\model.properties
model.notification.host= <IP>
model.notification.serverobject.host= <IP>
On the Monitor: \Vontu\Protect\config\model.properties
model.notification.host= <IP>
model.notification.bindaddr= <IP>
\Vontu\Protect\bin\NotificationTrafficMonitor.lax
lax.command.line.args=<IP>:37328
