Charlie and Matthew,

The only problem I saw was related to the tap driver not being released 
due to IPsec policies not being cleared out properly. This was a bug I 
introduced recently while trying to fix a lock recursion issue and may 
have been munging things up. Could you please try the following ...

cd <ike dir>
svn update
make clean
rm CMakeCache.txt
make install
setkey -F
setkey -FP
/etc/init.d/iked stop
/etc/init.d/iked start

... and try to connect again. If you still having problems, please let 
me know and we can investigate further. It seems to be working fine on 
my FC6 and Kubuntu 4.07 test hosts. I'm confident we can make it work 
again :)
