PortProxy 95 -- the Windows 95 version -- running in the system tray using Wine on Novell openSUSE 10.2. PortProxy is the icon closest to the right, next to the clock
PortProxy is a TCP connection forwarding service that I wrote in college so that I could run servers from behind a firewall. When I put Linux onto resnet.bryant.edu, I no longer needed this program, but it's still cool if you are running Windows. I also wrote a version that runs as a system tray application in Windows 95.

Configuration
PortProxy stores its configuration in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PortProxy\Parameters registry key. It can be dynamically configured using a command line interface via a localhost telnet connection to port 256.
When connected to the configuration command line interface, the following commands can be used. Each command is terminated with a newline character. Responses from the server begin with either a plus sign (+) for a positive response or a minus sign (-) for a negative response, similar to DirList Server's protocol.
| Command | Parameters | Meaning |
|---|---|---|
| + | port intaddr intport 6 | Adds a forwarded port
|
| - | port | Removes a forwarded port
|
| s | port | Returns whether or not the given local port is being forwarded by PortProxy
|
| t | port | Tests a local port for use by PortProxy or another application
|
| x | Closes PortProxy | |
| n | No operation (no-op) |
