There are 3 different ways to set up your local bridge, each with their own pros and cons:
1. Configure a private bridge
* Only your clients use this bridge
* No cover traffic
2. Configure a bridge distributed by BridgeDB
* Your clients and other clients may use your bridge as the first hop
* BridgeDB doesn't distribute all bridges straight away, so you may or may not get cover traffic
* You can't separately rate limit external and local traffic at the bridge itself - RelayBandwidthRate includes all bridge traffic
3. Configure the server as a relay, but configure the clients to connect to it as a bridge
* If you configure a client with a mandatory guard relay using EntryNodes and StrictNodes, the relay must have and maintain the guard flag. But configuring clients with a relay server in a "bridge" config line avoids the need for a guard flag.
* Your clients use this bridge, as do other clients as at least a middle hop, and a guard or exit hop depending on flags
* You get the most cover traffic this way
* You can't separately rate limit external and local traffic at the bridge itself - RelayBandwidthRate includes all relay and bridge traffic
* This mode of operation is less common, and may reveal some bugs in Tor. In my experience it has worked fine for months with 0.2.5 - 0.2.7-alpha, but please report any issues on https://trac.torproject.org/projects/tor/ticket/1776
* As a precaution, if you ever reconfigure a relay Tor node as a bridge Tor node, please delete the keys so it appears as a new bridge in BridgeDB.
