The following software is currently available:

• PPTP client packet reordering (Docs), a fresh implementation of a simple packet queue, now integrated into pptpclient CVS.
• PPP DHCP client plugin (tarball) for IP address allocation by a DHCP server (based on udhcpd from Busybox.
• IPtables Byte Limit match, a patch against iptables 1.2.7a which adds support for matching packets at a certain data rate, and which can therefore be used for simple QoS (quality-of-service) control. (updated 22/Jan/2003)
• IPtables MAC/IP Pair match, a Patch-O-Matic patch set for Netfilter Patch-O-Matic which adds the ability to match large numbers of IP and MAC address pairs, to detect and prevent IP spoofing on large untrusted networks. (updated 08/Apr/2004)
• VRRPd Daemon Mode patch, which adds a -D option to VRRPd, causing it to close standard file descriptors and go into the background. The patch also cleans up some failures to null-terminate strings, and the formatting of the usage message.

This software is used in our FireRack firewalls. Due to its free nature, no official support is available without a support contract, but unofficially you can e-mail support@netservers.co.uk if you have comments, questions or suggestions, and we will do our best to help you, time permitting.
