Portfwd(8)		    System Manager's Manual		    Portfwd(8)

NAME
       Portfwd - Port forwarding daemon

SYNOPSIS
       portfwd -h
       portfwd -v
       portfwd [-d ...]	[-g] [-t] [ -c config-file ]

DESCRIPTION
       This manual page	documents briefly the Portfwd program.

       Portfwd	stands	for port forwarding daemon. It's a small userland tool
       which forwards incoming TCP connections and/or UDP datagrams to	remote
       hosts.  There  is support for FTP forwarding, transparent proxy,	DNS on
       demand, simple round-robin load-balacing, external  destination	selec-
       tors and	other minor features.

       This  author's English skills are very bad as he's not a	native speaker
       of that language	-- please feel free to contribute fixes	for this  page
       if you can.

OPTIONS
       The  program  follows  the usual	GNU command line syntax, with long op-
       tions starting with two dashes (`-').  A	summary	of options is included
       below.

       -h, --help
	      Shows summary of options.

       -v, --version
	      Shows program version.

       -d, --debug
	      This option increases logging  verbosity	for  debug.  Up	 to  3
	      switches are meaningful. Failure messages	are sent to the	system
	      log under	daemon facility.

       -g, --foreground
	      Specify this option to keep the daemon running in	foregroud.

       -t, --transparent-proxy
	      This  switch enables transparent proxying. If you	intend to for-
	      ward data	to hosts behind	your masquerading firewall, you	proba-
	      bly want this option turned on; it allows	your  servers  to  see
	      true IP addresses	of clients.

       -f, --on-the-fly-dns
	      Portfwd  usually	solves all DNS hostnames upon startup. Specify
	      the -f option if you want	the destination	hostnames  be  updated
	      on demand. Be aware this can affect TCP connection times and the
	      whole UDP	forwarding performance.

       -c, --config config-file
	      This argument allows specification of a configuration file other
	      than  the	 hard-coded default.  config-file is the full pathname
	      to the configuration file.

FILES
       /usr/local/etc/portfwd.cfg
	      Default configuration file. This may be changed by the  "config-
	      ure" script in compile time.

SIGNALS
       SIGTERM
	      If sent to Portfwd master	process	(the one with lowest PID), the
	      TERM signal terminates the whole forwarding job.
