Using Bridge Mode With the VPN Device
The VPN device has two basic operating modes:
•
router
•
bridge
VPN devices are usually deployed as routers, which is the default
configuration. In certain network topologies, however, it is
advantageous to configure a VPN device in bridge mode. The
difference between router and bridge mode is how the VPN
device is assigned IP addresses and how the VPN device handles
Address Resolution Protocol (ARP) requests that it picks up on
the network.

Note: Switching from bridge mode to router mode or from
router mode to bridge mode requires you to reboot the VPN
device.

In router mode, each physical interface on the VPN device must
be assigned an address from a different subnet. For example,
Ethernet 0 could be assigned 192.168.1.1 and Ethernet 1 could be
assigned 172.16.1.1.
Use the
interface
command when you assign addresses to a
VPN device that operates in router mode. To assign the
addresses from the command line, use the following format:
hostname: NORMAL# config
hostname [config]: NORMAL# interface e 0
hostname [config] [int e 0]: NORMAL# ip
address 192.168.1.1 255.255.255.0
hostname [config] [int e 0]: NORMAL#
interface e 1
hostname [config] [int e 1]: NORMAL# ip
address 176.16.1.1 255.255.255.0
hostname [config] [int e 1]: NORMAL# end
hostname: NORMAL# write
