I have been using it for several months on a 2.0.25 system. It's
linking me to the world right now (I like to appear on a different
segment than I am physically in order to keep my machines grouped
together administratively). I would like to know how to get two tunnels
up .. can one load two drivers?

My only problem is that I don't seem to tunnel some sun rpc protocol
packets - whatever it is that rusers and ruptime uses in particular.
This is a nuisance as some of my update scripts depend on
rusers/ruptime. I don't think broadcast packets go through the tunnel
either. Perhaps I just don't know how to make them go through.
