+[[BandwidthRate]] **BandwidthRate** __N__ **bytes**|**KBytes**|**MBytes**|**GBytes**::
A token bucket limits the average incoming bandwidth usage on this node to
the specified number of bytes per second, and the average outgoing
bandwidth usage to that same value. If you want to run a relay in the
public network, this needs to be _at the very least_ 30 KBytes (that is,

If set, we will not advertise more than this amount of bandwidth for our
