UAG CLI Reference Guide 111
CHAPTER 15
IP Drop-In
This chapter explains some commands you can use to set the UAG interfaces to work in drop-in
mode.
15.1 Drop-In Mode Overview
When the UAG is in drop-in mode, you can deploy it in your existing network without changing the
network architecture and use its multiple WAN feature to connect to more than one ISP. Before
deployment, you need to set one WAN interface and one LAN interface on the UAG to work in drop-
in mode. The drop-in WAN interface can connect to the original ISP. The drop-in LAN interface is
connected to the existing NAT router or firewall (if any) in your network. A second WAN interface
which is not in drop-in mode is connected to another ISP. You can use trunks for WAN traffic load-
balancing to increase overall network throughput and reliability.
Note: The WAN interface (ge1, for example) in drop-in mode must use a static IP
address. You must disable the DHCP service on the LAN interface (ge4, for
example) in drop-in mode via the web configurator or using the interface
interface_name no ip dhcp pool profile_name command.
In the following example, the drop-in WAN interface is ge1 and the drop-in LAN interface is ge4.
