Introduction A virtual private network, or VPN, allows you to securely encrypt traffic as it travels through untrusted networks, such as those at the coffee shop, a conference, or an airport. IKEv2, or Internet Key Exchange v2, is a protocol that allows for direct IPSec tunneling between the server and client. In IKEv2 VPN implementations, IPSec provides encryption for the network traffic. IKEv2 i

In remote access situations clients will usually send all their traffic to the gateway. Below we explain how this traffic can be forwarded and properly routed back to the roadwarriors. In some situations it might be more desirable to send only specific traffic via the gateway, for instance, to unburden it from forwarding web or even worse, file sharing traffic. Therefore, we also explain how to en

Update 04/20/2014: Adjusted to take into account the modular configuration layout introduced in strongSwan 5.1.2. Tweaked cipher settings to provide perfect forward secrecy if supported by the client. This article is a step by step guide on how to prepare strongSwan 5 to run your own private VPN, allowing you to stop snoopers from spying on your online activities, to bypass geo-restrictions, and t
Today I ran into a problem with IPsec Xauth PSK and the built-in Android VPN client (Android 4.1.2), resulting in some sites (such as www.yahoo.com) not loading through the VPN tunnel. Turns out I was dealing with MTU issues. When the Android VPN is started, it sets the MTU to 1500 on the tun0 interface: $ ip link show tun0 33: tun0: <POINTOPOINT,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOW
