Installation and Configuration Manual
3.1.2.2

Configuring the Device's DHCP Server

The device is supplied with an enabled internal DHCP server for the LAN and with default IP pool
addresses relating to the default subnet LAN. After reconfiguring the LAN IP addresses, the IP
pool addresses are changed accordingly. You can either disable the DHCP server or modify the
IP address pool. The device (acting as a DHCP server), uses this setting to allocate IP addresses
to all the computers connected to its LAN interface.
To configure DHCP on the device:
1. Access the device's Web interface, using the device's name ("msbg.home") or Voice and
Management IP address that you assigned in 'Assigning a LAN IP Address' on page 43.
2. Access the 'DHCP Server' page (Configuration tab > Data Settings menu > Services
submenu > DHCP Server).
3. Click the LAN Hardware Ethernet Switch link; the following page appears:
4. From the 'IP Address Distribution' drop-down list, select "DHCP Server".
5. Define the IP address pool using the fields under the 'IP Address Distribution' group.
6. Click OK.
7. If required, refresh the address by disconnecting the cable and then reconnecting it again, or
by performing the following in the Windows' command line interface:
ipconfig /release
ipconfig /renew
3.1.2.3

Assigning a WAN IP Address

Once you have configured the device's LAN interfaces, you can then define the device's WAN
interface (for connecting to the Internet). The WAN interface connection type can be one of the
following:
Manual IP address: defines a single, static IP address for connection to the WAN
Automatic IP address: the device obtains its WAN IP settings from a remote DHCP server
Point-to-Point Protocol over Ethernet (PPPoE): requires login user name and password
(supplied by your Internet Service Provider - ISP)
Point-to-Point Tunneling Protocol (PPTP): similar to PPPoE, and requires PPTP server IP
address etc. (supplied by your ISP)
Layer 2 Tunneling Protocol (L2TP): similar to PPTP
Notes:

Figure 3-6: Configuring the DHCP Server

Before you configure the WAN interface connection, ensure that you have all the
required information from your ISP.
Once you have configured the WAN IP address, you must define the SIP WAN IP
address with this same IP address in the Voice and Management interface.
