ipsec-tools

[rys61]

I needed to setup a VPN connection to a Draytek router (Vigor 2910) and as I couldn't get PPTP to work I tried IPSec.
After a lot of Googling and testing I finally got ipsec-tools working.

I post it in three parts:
ipsec-tools (setkey racoon racoonctl) - for setting up IPSec and exchanging keys.
ipsec-modules af_key.ko xfrm_user.ko - modules needed by ipsec-tools for kernel 2.6.25.16 (run depmod -a after installing!)
draytek-vpn.tar.gz - simple script for connecting to Draytek router

NOTE that ipsec-modules is for the kernel in 4.1.2 (which I use) and if you use a different kernels (as I think the latest PUPPY does) you need to compile kernel modules for that kernel.
