11.2.3. Editing A Logical Interface (Bridged)
Figure 11.4. Edit Logical Interface (Bridged)
The Description field attaches a description to the logical interface viewable from the network
interfaces menu.
The VPI field determines the VPI number the connection uses. The default of 0 is correct for most
providers.
The Attempt ATM Autoconfiguration option causes the router to attempt to automatically determine
the VPI and VCI used on the connection. This does not work with all providers and may case the
connection to fail even if the link light is on. If this option is used it should only be used to find out what
the correct values are if your provider isn't willing to help you, and when the correct values are found
it should be disabled with the correct values entered in the VPI and VCI fields instead.
The VCI field determines the VCI number the connection uses. The default of 35 is correct for most
providers.
The Use DHCP field forces the router to fetch its IP address from the peer via DHCP. Note that
DHCP is selected the local and remote IP addresses are immediately dummied out to 169.254.0.1
and 169.254.0.2, the netmask is set to 255.255.0.0 and default gateway option is suppressed.
The Local IP Address field defines the IP address for this interface.
The Netmask field defines the network address mask The value 255.255.255.255 specifies a point-
to-point connection which is almost always correct.
The Remote IP Address field defines the IP address for other side of this interface. As most WAN
links are of point-to-point type, there is only one host connected to the other end of the link and its
address is known in advance. This option is the address of the 'other end' of the link and is usually
assigned by the network administrator or Internet service provider.
