Untangle Transparent Bridge Technology

If you already have a router/firewall and want to keep it installed, simply install the Untangle Server between the firewall and the main internal switch. In this scenario, the Untangle Server will function as a bridge. You do not need to change your default route (gateway) on any computers behind the firewall, nor change the routes on your router.

You can also install the Untangle Server as a bridge between the firewall and the Internet device. This configuration is not recommended because Denial-of-Service protection within the Untangle Server will not be able to differentiate between internal machines behind your firewall. Also, Untangle Reports will not be able to differentiate between internal machines behind your firewall.
