[edit] Introduction

Openswan is an implementation of IPsec for Linux. It supports kernels 2.0, 2.2, 2.4 and 2.6, and runs on many different platforms, including x86, x86_64, ia64, MIPS and ARM.

Here I've copy and pasted the discussion about OpenSwan from the main page to help get started:

"We need to get some instructions going in here for how to load ipkg modules. I'm particularly inertested in getting OpenSwan (http://www.openswan.org) running on DD-WRT. Here's a link to some instructions for OpenWRT (http://openwrt.org) , but I'm not sure they work in DD-WRT:

[edit] Installation

You must have an operational Jffs configuration to install OpenSwan.

Install OpenSwan by issuing the following command:

ipkg install openswan

If the installation fails, as it did in my case, try issuing the following command:

ipkg -force-depends install openswan

[insert script to load kernel module and ipsec client here]

[edit] Use

Here should be instructions on how to use it once it's installed
