Configuring network settings
To configure the network settings on the ISDN gateway and check the network status, go to Network
> Port A or Network > Port B.
The ISDN gateway has two Ethernet interfaces, Port A and Port B. The configuration pages for the two
interfaces look and behave similarly, and so are described together. Differences will be noted as
appropriate.
Port A can be configured to be allocated its IP address by DHCP. Port B cannot use DHCP. Connect Port
A to your local network and connect Port B to a second subnet or the internet depending on your
application of the ISDN gateway.
In this section:
IP configuration settings
IP status

IP configuration settings
These settings determine the IP configuration for the appropriate Ethernet port of the ISDN gateway.
When you have finished, click Update IP configuration and then reboot the ISDN gateway.

Field description
IP
Specifies whether the port should be
configuration
disabled or enabled, and, if enabled,
whether the ISDN gateway obtains its
own IP address for this port automatically
via DHCP (Dynamic Host Configuration
Protocol), or whether or if it should use
the values that you specify in the Manual
configuration fields below.
Manual configuration
IP address
The dot-separated IPv4 address for this
port, for example 192.168.4.45.
Subnet mask
The subnet mask required for the IP
address you wish to use, for example
255.255.255.0

Usage tips
Click Renew DHCP to request a new IP
address if you have selected automatic
configuration.
Port A should never be disabled because it
is the primary interface of the ISDN
gateway.
You only need to specify this option if you
have chosen Manual IP configuration, as
described above.
For Port A, if the IP configuration setting is
set to Automatic by DHCP this setting will
be ignored.
