Setting Up and Using Secure IP (IPsec) The IPsec (secure IP) protocol suite and associated tools provides the ability to encrypt and authenticate IP packets transmitted between cooperating hosts or subnets.
Configuring IPsec on Red Hat Enterprise Linux can be done via the Network Administration Tool or by manually editing networking and IPsec configuration files. For more information about using the Network Administration Tool , refer to the Red Hat Enterprise Linux System Administration Guide . It was discovered that a specially-crafted packet sent to the racoon ipsec key exchange server could cause a tunnel to crash, resulting in a denial of service. On a découvert qu'un paquet conçu spécialement envoyé au serveur d'échange de clefs ipsec racoon pouvait causer le plantage d'un tunnel, entraînant un déni du service. I think I need racoon and ipsec-tools. The other half of the question is this:I have heard that IPsec is part of the IPv6 standard. Does that mean that once I set it up, I will be able to encrypt my connections to any of the IPv6 services I connect to? IPSec requires a set of kernel modules to be loaded or built in, but outside of that you don't really need to do anything to the kernel; it's just daemon configuration like any other server after that. I'm afraid I haven't used Openswan, so I'm probably not very useful with that particular setup. IPsec traffic that is destined for the local host (iptables INPUT chain) IPsec traffic that is destined for a remote host (iptables FORWARD chain) IPsec traffic that is outgoing (iptables OUTPUT chain) Warning¶ In the course of the tutorial, firewall rules will be modified. This approach only works with kernel processing of IPsec traffic.
Linux racoon IPsec daemon can be configured through /etc/config/racoon. This document is in an advanced beta state.
Aug 12, 2015 · The racoon/IPsec-tools package is largely unmaintained without any clear leadership or oversight. While CVE-2015-4047 provoked a flurry of activity to resolve the situation it is yet to be completely resolved to a suitable level. Portability / Deployment On this criteria racoon/IPsec-tools rates acceptable.

The third problem is that if the IPsec configuration has not been loaded for some reason, perhaps because the racoon daemon failed to start correctly, then network traffic destined for the remote network will be sent out of the WAN interface unsecured and destined for whichever host may be listening on the appropriate address on that network segment.
