Some time ago, I've posted on the Vyatta Users forum about an issue regarding L2TP/IPsec remote access VPN.
For some reasons, things went sideways, and an ambiguous situation reigned.
On 26.08.2008, on the Vyatta Users forum, an announce was made, that a Security Reference document is available for download at http://www.vyatta.org/documentation.
Within that document, Chapter 4 Remote Access VPN Overview, section Remote Access VPN configuration, topic Remote Access VPN Deployment Issues, L2TP/IPsec part, Vyatta documented that issue.
Vyatta provide a solution using iptables for Glendale(VC4).
Starting with Hollywood(VC4.1), the issue can be addressed directly from the CLI, a configuration example being presented.
Vyatta kept their word, and both documented and addressed the respective issue.
For doing that, three big Hip Hip Hoorays from me today for Vyatta in the security area.
