source addresses for outgoing connections can be explicitly specified or automatically selected by the system.

structured configuration language allows specification of multiple simultaneous forwarding processes.

portfwd spawns one forwarder process for each set of ports which are subject to the same rules. within a process, portfwd uses a select()based eventloop to concurrently handle several network events. there is no threading. there is no further process creation after the startup of the configured daemons.

the destination of a connection/datagram can be selected based on its source address/port pair.

portfwd allows simple roundrobin loadbalancing through specification of multiple destinations.
