Security [CVE-2006-5873]: Rhys Kidd identified a vulnerability in the handling of heartbeat packets. Drop oversize heartbeat packets.

Note: If clustering is not being used, simply dropping packets to UDP port 32792 on the server is recommended and will avoid the vulnerability.

Release 1.1.0 of L2TPS has just been completed. This release is a huge improvement over the previous release in terms of configurability and stability.

It's now possible to configure almost everything in a running instance by the command-line interface, so it should almost never require dropping any connections.

Also a number of stability bugs have been fixed, after seeing some higher load in the last few months.

I'm pleased to announce the first public release of L2TPNS.

L2TPNS is a LNS endpoint for L2TP tunnels. It handles the L2TP protocol internally, as well as the PPP protocol. It is very fast and can handle thousands of simultaneous users, and multiple megabytes/second of traffic.

Also supported is RADIUS for user authentication, a walled garden for users who fail authentication, speed throttling, traffic interception, usage accounting and hot-standby clustering capability.... read more
