Bluntly put, but very accurate :)

I want it to do something pf cant - port forward ipsec packets for 
Android L2TP/IPSec. Apparently (according to pfsense experts) it is 
impossible until Android 3.0 or 4.0. My next port of call will be 
ipfilter, and thats a known working solution but I want to use more 
robust native tools.

As for being a pita - I don't know. It doesn't seem any harder to me, 
could even be easier; seems to be a psychological thing. I'll get back 
to you (the list) when I have achieved an outcome and let you know. So 
far I haven't had to compile a new kernel, so thats a definite plus... 
that could change though. More info in the next episode ;) I've just 
finished wrestling with certificate generation.... grr! It was easier 
last time, not sure what has been the issue this time.
