README for ipsec-tools REQUIREMENTS For ipv4 IPSEC you'll need to enable: CONFIG_XFRM_USER CONFIG_NET_KEY CONFIG_INET_AH CONFIG_INET_ESP CONFIG_INET_XFRM_MODE_TRANSPORT CONFIG_INET_XFRM_MODE_TUNNEL PRE-INSTALL POST-INSTALL RESOURCES PRECAUTION This is a very important piece of software, test your configuration (try to capture/analyze some data) before production use. Both transport and tunnel mode was tested for ipv4, but I am unsure if automatic keying will work out of the box - no rc file for racoon is provided for now. Any suggestions on template configurations from people who use racoon in real life are welcome.
