portfwd is a small user-level daemon which forwards incoming TCP connections and/or UDP packets to remote hosts. Multiple forwarders can be specified in a flexible configuration file. There is support for FTP forwarding and transparent proxy.
Release Notes: A 'fragile' configuration keyword was added to make the daemon quietly retry connections against unstable servers. The maximum number of open file descriptors now defaults to FD_SETSIZE.
Release Notes: A minor bugfix against the previous pre-release.
Release Notes: A bug in FTP forwarding has been fixed.
Release Notes: Compatibility changes for compilation under gcc 3.2 have been added.
Release Notes: Portability fixes have been added for Solaris and FreeBSD.
