Free linux upnp internet gateway device project software for linux

The Linux UPnP Internet Gateway Device Project is an attempt to begin work on a UPnP Forum-compliant Internet Gateway Device. It allows Windows Messenger or other this kind of programs to use voice/video through a Linux firewall running Iptables.
This program only creates DNAT (portmap) entries in you firewall on the external interface (public ip). Any other firewall code must be set to allow basically all tcp and udp through the FORWARD chain to your client machines, and the client machines must be able to contact the firewall using tcp and udp through the firewalls INPUT chain on it internal interface.
We will be adding some checks to see if FORWARD has a default policy of DROP or REJECT, however placing rules once we determine this is a bit tricky. Theres at the moment no real way to check to see if a packet matchin this rule will pass through any additional rules that may be located above it. Also, we will probably need to check for any rules below as well. Hopefully we can get this implemented soon.
In the meantime, please be aware of this fact, and if you are seeing Advertisements sent in the /var/log/debug file (or whatever you have syslog set to log DEBUG level messages to), but you are not seeing AddPortMaps, the most likely this is the problem, or it could be the following problem.
UPnP works with the 239.0.0.0/255.0.0.0 multicast addresses. Windows Messenger may also send request to a Unicast address, and thus the reason for the patch to the UPnP source code for this to work. Nevertheless, to add a route in your box for the multicast address, just use the following command, replaceing with the interface name of your inside interface name (i.e., eth0).
Enhancements:
- Fixed issues with Direct Play games not deleting broadcast port mappings So most if not all Direct Play games will now work correctly.
- Added Byte and Packet counter code contributed by giussani
- Changed all the xml and skl files to include our UUID and some other updatet information that needed to be changed.
- Added a CREDITS file to make sure I give thanks to the person who inspired me to write this program, along with everyone else whos contributing.
- Fixed the startup message in messages to report the correct version now.
- Once again, other small changes i cant remember

MiniUPnP Client and Daemon is an UPnP IGD client lightweight library and UPnP IGD daemon.
The UPnP protocol is supported by most home adsl/cable routers and Windows 2K/XP. The aim of the MiniUpnp project is to bring a free software solution to support the "Internet Gateway Device" part of the protocol.
The Linux SDK for UPnP devices (libupnp) seems too heavy for me. I want the simplest library possible, with the smallest footprint and no dependencies to other libraries such as XML parsers or HTTP implementations. All the code is pure ANSI C.
Compiled on a x86 PC, the miniupnp client library have less than 15KB code size. For instance, the upnpc sample program is around 20KB.
The project is divided in two main parts : the client library, enabling applications to access the services provided by an UPnP "Internet Gateway Device" present on the network, and the miniupnpd daemon, providing these services to your network from a linux or bsd box being the gateway. At the moment the miniupnpd is developped on OpenBSD 3.0+ with pf. You can see some of the work I have done to integrate with pf on this page.
As pf is also available under FreeBSD, guys at the pfSense project have ported miniupnpd to this system.
For some reasons, it may be not the good solution for you to use the code from the MiniUPnP project directly.
As the code is small and simple to understand, it is a good base to take inspiration for your own UPnP implementation. The KTorrent team UPnP plugin in C++ is a good example.
If you are wondering which home router is working with the miniupnp client, you can find the answer here. In fact, you are more likely to help me fill the list by sending me an email.
Usefulness of the miniUPnP client library
The usage of the miniUPnP client library is useful whenever an application needs to listen for incoming connections.
Examples : P2P applications, FTP clients for active mode, IRC (for DCC) or IM applications, network games, any server.
The typical usage of UPnP capabilities of a router is a file tranfert using MSN messenger. The MSN Messenger software uses the UPnP API of Windows XP to open port for incoming connection. To mimic the MS software, it is a good idea to use UPnP as well.
Enhancements:
- This release adds changes to accommodate the Linux 2.6.22 kernel.

Untangle Gateway Platform is a Linux-based network gateway with pluggable modules for network applications like spam blocking, Web filtering, anti-virus, anti-spyware, intrusion prevention, VPN, SSL VPN, firewall, and more.
- Commercial-grade open source alternative to SonicWALL and WatchGuard
- 14 integrated apps - use one or all of them
- Runs on off-the-shelf hardware
Enhancements:
- A package of 5.0.1 as a VMware Virtual Appliance has been released.

HP Linux Imaging and Printing Driver Project consists of two projects:

1) HPIJS, a printer driver for HP devices

2) HP Linux Imaging and Printing (HPLIP), a complete printing and imaging solution for Linux (note: HPLIP includes HPIJS).

Gateway is a JavaEE application developed by the Vermont Department of Taxes. It provides a web services framework for accepting Streamlined Sales Tax registrations and returns.

The project also includes a web interface for manually submitting transmissions. The goal is to build an extensible framework upon which future tax services can be built.

Proxmox Mail Gateway project addresses the full spectrum of unwanted e-mail traffic, focusing spam and virus detection.
E-mail security begins at the gateway by controlling all incoming and outgoing e-mail messages. Proxmox Mail Gateway addresses the full spectrum of unwanted e-mail traffic, focusing spam and virus detection.
Proxmox Mail Gateway uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.
Every single e-mail will be analyzed and gets a spam score assigned. The systems attempt to optimize the efficiency of the rules that are run in terms of minimizing the number of false positives and false negatives.
The flexible architecture combined with the easy-to-use configuration interface safeguards companies against existing and new e-mail threats.
Main features:
- Advanced spam detection
- Virus removal including phising e-mails
- Automatic update of virus signature database
- Automatic installation within minutes
- Support for standard PC / Server hardware (i386)
- SCSI and SCSI raid support
- Secure web based configuration
- Object-oriented rulesystem
- Attachment blocking
- Advanced statistics
- Daily reports
