User's Manual 6. Configuring the MediaPack
Version 2.2 119 July 2007
Note: If the DHCP server denies the use of the gateway's current IP address and
specifies a different IP address (according to RFC 1541), the gateway must
change its networking parameters. If this happens while calls are in
progress, they are not automatically rerouted to the new network address
(since this function is beyond the scope of a VoIP gateway). Therefore, you
are recommended to configure DHCP servers to allow renewal of IP
addresses.
¾ To configure the IP interfaces parameters:
1. Open the ‘IP Interfaces' screen (Advanced Configuration menu > Network Settings
> IP Interfaces option).
Figure 6-19: IP Interfaces Screen
2. Configure the IP interfaces according to Table 6-17.
3. Click the Submit button to save your changes.
4. To save the changes to the flash memory, refer to Section 'Saving Configuration
Settings on the MediaPack' on page 146.

Default LAN IP address: 192.168.1.1 (subnet mask: 255.255.255.0)
Subnet Mask
Defines the network mask of the IP address specified above.
MTU
