Hi

I'm becoming very frustrated with IPSEC these days. I've been trying to set up strongswan, but there are no good guides out there, I think?. It's allways like something is missing or is not mentioned.

I'm totally new to IPSEC on Linux, so do any of you know any good newbie guides out there?

My setup is as follows:

PrivateIP_Host <-> NAT Router <-> PublicIP_Host

Both the hosts have CentOS 5.6 Installed with no GUI, so I'm stuck with the console. After searching around I found that racoon is preinstalled in CentOS, so maybe that's the solution?


Thanks in advance!

Yes you can have vpn-ipsec tunnel from client behind nat to server.
Please post your configuration files of setkey.conf and racoon.conf
Which method you are using preshared key or Certificate ?

Thanks
