Hello all, I am successful in setting up IPSec with preshared keys (both transport and tunnel ) using racoon between two Suse Linux 10 machines which uses openswan and comes pre-configured. I would like to know if there is already UDP encapsualation capability integrated with Freeswan implementation on Suse Linux ( kernel release 2.6.13-15). Because the README files for NAT traversal says, I need to patch up the kernel. Do I have to do it and if yes, where to get the patches from, kindly point me to the right direction. If anyone has any more info, a how to or related info that can be shared, would be very much helpful, thanks and regards, pj
