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:
When Drop-in Mode is enabled, the LAN ports and the WAN1 port are bridged.
When operating in Drop-in Mode, PePLink Balance forwards the traffic between the LAN
hosts and the router for WAN1 without performing any IP address translation. Hosts on the
LAN will not notice any change in the IP addresses of the hosts on WAN1, and vice-versa.
However, although the IP addresses on all of the forwarded packets remain the same,
PePLink Balance inserts its own MAC address in place of the original. As a result, MAC
address changes will be noticed by hosts on both the LAN and the WAN. Further details will
subsequently follow.
After successfully setting up PePLink Balance as part of the network via Drop-in Mode, a
PePLink Balance 200 unit will accommodate one additional WAN connection; PePLink
Balance 30, 300 and 380 will accommodate two additional WAN connections; PePLink
Balance 700 will further accommodate six additional WAN connections.
