Let diameter_{tcp,sctp} be configured with permissible remote addresses
Option 'accept' allows remote addresses to be configured as tuples or regular expressions. The remote addresses for any incoming (aka accepted) connection/association are matched against the configured values, any non-matching address causing the connection/association to be aborted.
