Chapter 10 - Configuring PPPoE/Bridged Mode On ADSL
Editing A Logical Interface (Bridged)
Figure 83: 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.
The Gateway IP Address field defines the IP address to use as the gateway for
sending to other sites. This is usually the same as the Remote IP Address.
