Project status
[done] - tasks that are completed
- Create framework (sockets, interfaces detection)
- Forwarding path (lan interface to wan interface)
- Mapping management (after packet is forwarded, mapping is created for handling returning reply)
- Configuration parameters (hardcoded for now)
- Parameters must be configurable from the command-line
- End-to-End UDP traffic over IPv4 is working
- UDP traffic (PMP-NAT) must be handled
- Build the code on mips architecture
- Perform end-to-end testing (NAT-PMP)
- Prepare OpenWRT package
- UDP traffic (uPNP) must be handled
- TCP traffic (uPNP) must be handled
- Prepare documentation
- Add support for uPNP traffic
- Test end-to-end uPNP
- Add mapping timeout garbage collector
- Implement port forwarding GUI
- Implement portproxy GUI
- Make the configuration persistent (saved across reboots)
- Prepare documentation
- GUI: Port forwarding page
- GUI: Portproxy monitoring
- GUI: softwire configuration
- Migrate to /branches/8.09/ OpenWRT revision

| all snapshots | List of all snapshots. |
| 2010-03-02 | Portproxy update. It now supports --persistent parameter. It is possible to specify to bind IPv6 address or interface, even when this interface or address is not available yet. If socket binding fails, portproxy will sleep for 10 seconds and then try again. Also, if IPv6 address is not specified, portproxy will try to read it from specified WAN interface (--wan-interface). |
| 2009-12-29 | Complete code drop, with firmware images, documentation and source code. Extended NAT-PMP support added. First code drop with GUI supporting manual port forwarding and portproxy interface. |
| 2009-12-03 | Latest portproxy source code. |
| 2009-11-04 | Firmware image with ds-lite configuration GUI. There are 4 pages available: port forwarding, tunnel configuration (manual or via DHCPv6), automatic portproxy control and port forwarding rules limit. GUI is LuCI based. |
| 2009-10-22 | Firmware image with latest portproxy and extended GUI with lots of extra features. Portproxy properly handles NAT-PMP and UPnP traffic. GUI is LuCI based. |
| 2009-10-04 | Firmware image with portproxy and web GUI. Softwire tunnels may be configured (necessary modules are included in the firmware). NAT-PMP traffic is verified to be working both over Ethernet and Softwire as well. Example capture is attached. |
| 2009-10-01 | First working portproxy version. UDP traffic is forwarded between LAN and WAN, both ways.
It was tested over IPv4. Traffic over IPv6 tunnel is next.
First image based on OpenWRT r15834. To run the code, issue following command: portproxy -l lanIPv4 -w wanIPv4 -n routerIPv4 |
| 2009-09-29 | Command-line parsing added. First (untested) OpenWRT package create. |
| 2009-09-28 | First code snapshot. Forwarding UDP packets is working. The code is highly experimental. All parameters are hardcoded for now. |
| 2009-09-14 | Work on portproxy started. |
