Does fbsd support NAT-Traversal IPSEC VPNs?

[Stephan Eckweiler]

I found for netbsd a kernel config named "options IPSEC_NAT_T", this doesn't exist (I have fbsd 6.0 stable). Also OpenBSD has support since 3.6.
   
  Is there any way to get Nat-Traversal run, or whatever thing to encapsulate esp-packets into UDP? I'm using racoon, out of the ipsec-tools Port, which has at least such options in racoon.conf. But when I say 
   
    racoon -f /usr/local/etc/racoon.conf 
   
  and include 
   
    nat_traversal on; 
   
  the daemon doesn't start, my log says 
   
    compression algorithm cannot be checked because sadb message doesn't support it.
   
  Thanks in advance
  
Stephan
