Hi Rene, I've been testing the new native ipsec stack with FreeSwan and encountered an issue with NAT-T.
Pluto states.... Mar 31 16:54:29 fireone pluto[3941]: Starting Pluto (FreeS/WAN Version 2.04 X.509-1.5.3 LIBCURL LDAP_V3 SMARTCARD PLUTO_USES_KEYRR) Mar 31 16:54:29 fireone pluto[3941]: including NAT-Traversal patch (Version 0.6b) [disabled] Mar 31 16:54:29 fireone pluto[3941]: Using Linux 2.6 IPsec interface code Indicating that the ipsec stack lacks NAT traversal, In the usr/doc you state... ....this native Linux IPSec stack is of high quality, has all of the features of the latest Debian FreeSwan packages (i.e. support for other ciphers like AES and NAT Traversal support) and is well integrated into the kernel networking subsystem (which is not true for the FreeSwan kernel modules). Is there an incompatibility here, or am I missing something on how to enable the NAT traversal. I'm using the Debian native 2.4.25-1-686 kernel. Cheers, Lewis
