The MiniUPnP project is a library and a daemon. The library is aimed to enable applications to use the capabilities of a UPnP Internet Gateway Device present on the network to forward ports. The daemon adds the UPnP Internet Gateway Device functionality to a NAT gateway running OpenBSD/NetBSD/FreeBSD/Solaris with PF/IPF or Linux 2.4.x/2.6.x with netfilter. One of its most interesting features is to enforce some permissions to allow or deny redirections, bringing some security to UPnP. Newer versions also support the NAT-PMP protocol from Apple.

Release Notes: Some fixes were made to the daemon for NetBSD and ipf. A serious fix was made for Linux systems using netfilter 1.4.3 or later. The client now ignores EINTR during connect() calls. Compilation fixes were made for Solaris, Mac OS X, and other systems. Fixes were made in the Python module. The MX: SSDP field value was corrected.


Release Notes: In the daemon: small bugfixes, working upnp events, support for iptables >= 1.4.3, correct reporting of unconnected status, and reloading from the lease file. In the client: the addition of the ExternalHost argument and small fixes.


Release Notes: Compatibility with ipf under FreeBSD was improved. You can now run MiniUPnPd and MediaTomb on the same computer. The documentation was updated. MiniUPnPc installation was fixed. MiniSSDPd is now used (optionally) by both the client and the server software.
