Aha! 

I fixed the NFS tunnel going over the LAN. I was executing openvpn from a
startup script that was somehow swallowing the fact that when openvpn runs as a
client, there is a segmentation fault happening during the TLS handshake!
Looking at that closer with gdb revealed the fact that the crash happens in
libcrypto. 

This actually makes sense in retrospect, since I upgraded libcrypto for some
Apache stuff I was doing a long time ago. I haven't restarted gatekeeper since
then so the NFS tunnel continued to work for me all this time and I didn't
notice that I broke OpenVPN until I tried to connect to my network wirelessly a
few days ago.

I recompiled OpenVPN and was able to re-establish the NFS tunnel. I can't test
the wireless one right now b/c I am doing all this remotely from work, but I
will try it tonight.

Thank you to all that responded or thought about responding :)

Val
