FastFwD is a small daemon that allows users to set up port forwarding from a source IP address and port number to a target IP address and port number easily without the need to deal with complicated ipchains/iptables-rules. FastFwD offers a fault-proof possibility for port forwarding between two networks or IP addresses and additionally gives the possibility to password-protect this connection. FastFwD has been tested for Linux and QNX and should compile and work with all POSIX-based systems.
