rconn [R(everse) Conn(ection)] is a multiplatform program designed for creating reverse connections. rconn helps to get services that are behind a firewall and/or NAT without adding to firewall rules or port-forwarding. This is done by creating a connection, from the node behind the firewall/NAT to the port on your computer. This exposes a port on your machine to access the services behind the firewall/NAT. The initial connection is opened by the machine behind the firewall/NAT is used to route all the traffic.
