Howdy, This is (I hope) a final note on my problems with my VPN and my Airport Extreme Base Station.
It appears that the whole problem came down to a 'stuck' port ie a port that either dropped incoming packets or sent them to an unspecified port...In this case upd ports 500 and 4500 were the culprits. These ports are essential for at least the setting up of the VPN. The fix was repeated uploading of the firmware and hard resets of the airport until the fault cleared. Note: If you have an Airport please export and save a configuration file. After one of the resets the Airport could not function or be configured until a configuration file was installed. Today I took down the VPN ( and racoon ) and tried to send a datagram with a simple text payload to port 500 on the server from a device not on the local network. I had a simple listener set set up on the server and the packet *was* passed through to the listener. Prior to the fix no packets were passed to the server on port 500. So for at least the Airport, the fact that Apple claims VPN passthrough has no impact incoming udp datagrams ie the Airport does not appear to be 'stateful' out of the box.
