{Hrelay} {UARG}
  The relay command allows the VPCS to become a virtual patch panel where
  connections can be dynamically changed using the {Hrelay} command.
  There are three steps required to use VPCS as a virtual patch panel.
  1. A relay {Hhub port} must be defined using the {Hrelay port} {Uport} command.
  2. Remote NIO_UDP connections (cloud connections in GNS3) use this {Hhub}
     {Hport} as the remote port, ensuring each NIO_UDP connection has a unique 
     {Hlocal} port (The local {Hport} numbers will be used to 'patch' the
     connection). VPC instances can be directed to use this hub port as
     their remote port using the command {Hset rport} {Uport}.
  3. The 'patching' is completed using the command:
     {Hrelay add} [{Uip1}:]{Uport1} [{Uip2}:]{Uport2}, where {Uport1} and {Uport2} are the
     {Hlocal} port numbers used in step 2.
  ARG:
     {Hadd} %s   Relay the packets between %s
     {Hdel} %s   Delete the relay rule
     {Hdel} {Uid}                        Delete the relay rule
     {Hdump} [{Hon}|{Hoff}]                 Dump relay packets to file
     {Hport} {Uport}                     Set relay hub port
     {Hshow}                          Show the relay rules
  Note: %s are 127.0.0.1 by default
