Initialization of change-relevant information in domain objects after calls to loadDB added. Some more cleanups to various methods as suggested by Luca.
This covers L2TP over IPsec (as supported by iPhone/iPad) and securing L2TP with iptables.
The story began a few days ago as I stumbled across the idea of having VPN connections from my iPhone/iPad to my servers. Even though there is loads of information about it on the net, there is nothing that really covers it thoroughly the way I needed it. To tell the truth: there is nearly nil information available on how to configure iptables on a 2.6 kernel to shield L2TP… well here is a try to help some of you guys.
Beware – these are examples are meant to allow you to create a 1:1 VPN to a single host/server. In order to build a VPN tunnel (1:n through a firewall) you will have to modify this a bit. If anyone is interested, let me know!
