By default, each new IP Office virtual machine deploys with two virtual network interfaces and two IP addresses, LAN1 and LAN2. If a duplicate IP address is detected, the IP Office application stops.

• For example, if you deploy two IP Office virtual machines and only configure the LAN1 address on each, the matching default LAN2 addresses (192.168.43.1) on each causes the IP Office application on both virtual machines to stop.

• During deployment, you must ensure that the deployment of each IP Office virtual machine is completed, including setting the required LAN1 and LAN2 IP addresses, before starting the deployment of another IP Office virtual machine.

• If the LAN2 port of an IP Office virtual machine is not required, you can disable it. This reduces the risks of conflicts. See Disabling a network port
