''This Provides an overview of IPsec in general. For information on the vtluug IPsec tunnel, see [[Infrastructure:IPsec]]''
'''IPsec''' is a method of running an encrypted overlay network, so as to protect traffic originating
from an unencrypted and/or untrusted network, such as a coffee shop's open WAP. It is among a number of
other protocols which can be used. L2TP/IPsec is one of the most common methods, although OpenVPN and IKEv2
also are viable, faster, and arguably more secure methods. The latter is supported in openiked developed by
the [[OpenBSD]] project. Most of this article assumes the use of IPsec/IKEv1
==Network-to-Network==
For purposes of this tutorial, we are setting up two endpoints, '''vpn1''' and '''vpn2''', both using IPv6 with the subnets '''2001:db8:1::/64''' and '''2001:db8:2::/64''', respectively.
