udppm - Man Page

UDP port mapper


pop3p [-ds] [-l[[@]logfile]] [-iinternal_ip] [-eexternal_ip] local_port remote_host remote_port


udppm forwards datagrams from local to remote UDP port



Inetd mode. Standalone service only.


Daemonise. Detach service from console and run in the background.


Be silenT. Do not log start/stop/accept error records.


External address. IP address of interface proxy should initiate datagrams from.  By default system will deside which address to use in accordance with routing table.


Internal address. IP address proxy accepts datagrams to. By default connection to any interface is accepted. It´s usually unsafe.


Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ preceeds logfile, syslog is used for logging.


Single packet. By default only one client can use udppm service, but if -s is specified only one packet will be forwarded between client and server. It allows to share service between multiple clients for single packet services (for example name lookups).


Increase or decrease stack size. You may want to try something like -S8192 if you experience 3proxy crashes.



- port udppm accepts datagrams


- IP address of the host datagrams are forwarded to


- remote port datagrams are forwarded to


Any UDP based application can be used as a client. Use internal_ip and local_port as a destination in client application. All datagrams are forwarded to remote_host:remote_port
