9 Drop-in Mode
Drop-in Mode (or transparent bridging mode) eases the installation of Peplink Balance on a live network
between the firewall and router, such that changes to the settings of existing equipment are not required.
The following diagram illustrates the Drop-in Mode setup:
Check the box Enable to enable the Drop-in Mode. After enabling this feature and selecting the WAN for
Drop-in mode, various settings including the WAN's connection method and IP address will be
automatically updated.
When Drop-in Mode is enabled, the LAN and the WAN for Drop-in Mode ports will be bridged. Traffic
going in between the LAN hosts and WAN router will be forwarded to each other. In this case, the hosts
on both sides will not notice any IP or MAC address change.
NOTE: PPTP server will be disabled under Drop-in Mode.
After successfully setting up Peplink Balance as part of the network via Drop-in Mode, a Peplink Balance
210 will accommodate one additional WAN connection; 310, 380, or 390 will accommodate two, 580 will
accommodate four, 710 will accommodate six, and 1350 will accommodate twelve additional WAN
connections respectively.
IMPORTANT NOTE for customers using Drop-in Mode and going to upgrade to firmware 5.0
MAC address passthrough for Drop-in Mode is implemented in firmware 5.0. If Drop-in Mode is enabled when user
is upgrading from previous firmware version, the ARP tables on the hosts on LAN and WAN segments have to be
flushed once or the hosts have to be rebooted. Otherwise, hosts on one side may not be able to reach hosts on the
other side of Peplink Balance until the old ARP records expire. Units without enabling Drop-in Mode are not
affected.
