Portfwd Alternatives

Portfwd

Portfwd, Port Forwarding Daemon, stands for port forwarding daemon. It's a small C++ utility which forwards incoming TCP connections and/or UDP packets to remote hosts.

FEATURES

-- Forwarding of TCP segments.

-- Forwarding of UDP datagrams.

-- Forwarding of FTP in active and/or passive modes.

-- Transparent proxying available under Linux. Portfwd detects
such facility in "./configure" time by searching the
definition of MSG_PROXY in .

-- DNS names for destination hosts can be resolved upon
start-up or on demand (see "on-the-fly" DNS option).

-- Portfwd can listen on specific local addresses.

-- 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 event-loop 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 round-robin load-balancing through
specification of multiple destinations.
