You can't have 2 separate LANs connected to the BCM450. The one port is the OA&M port for use by you as the support person and those LAN parameters cannot be changed in the BCM. The other 2 are. for practical purposes, a small 2-port switch. You can make 2 connections to the same LAN but that's about it. You assign the IP address to this connection (or let it DHCP to the network if you feel brave). Any and all IP traffic to and from the BCM is on this address so if you want to add SIP trunks, go ahead and direct them there.
