[Openswan Users] freeswan-1.99: cannot respond to IPsec SA

[Wolfman]

Hi,
I got a very similar Problem, if not the same:
I have the NAT-T patch installed and working (finally), but it didn't help. 
Some TIP: Kompile Kernel without patches, apply patch fox x.509, compile it 
again, apply NAT-T patch, compile it again. It really takes time, but 
whenever I tried it on another way, it failed. So this are nearly 5 
compiler runs.

Ok, back to the Problem, as I said, my NAT-T is working:
Mar 29 21:17:29 Linuxserver pluto[2218]: Starting Pluto (Openswan Version 
2.1.0 X.509-1.4.8 PLUTO_USES_KEYRR)
Mar 29 21:17:29 Linuxserver pluto[2218]:   including NAT-Traversal patch 
(Version 0.6c)

I found something in the google groups, that told me to write down the 
remote IP into my ipsec.conf. I did so, nothing changed
I pasted my ipsec.conf and my auth.log. If someone knows how to help, would 
be great.

psec.conf:

         nat_traversal=yes
