LAN/WAN Connection Options
•
A Bizfon IP PBX with an Ethernet WAN port behind a router, which is connected
to a cable or xDSL modem.
Fig. I-3: Configuration: Bizfon behind a router
In this configuration (Fig.I-5), the IP router typically acts as a DHCP server for the LAN and
assigns the IP addresses to the PCs and other devices. The Bizfon can be connected
through its WAN port directly to one of the router's LAN ports and will get an IP address
from the router. By default, the Bizfon acts as a DHCP client on the WAN port.
Please Note: Since Bizfon uses STUN by default, it will work with most basic routers
without any further configuration.
Please Note: Initially, the Admin PC must be connected to the Bizfon LAN port to access
Web Management of the Bizfon. Later, this PC can be moved to the router’s LAN. The
Bizfon Web Management can be accessed from any PC in the router’s LAN as soon as the
firewall is disabled on the Bizfon.
