Ooooh... was the original address an RFC 1918 address?  (10.x.x.x, 
172.16.x.x, 192.168.x.x?)

Perhaps they were giving you a non-routable addresses and when you call 
and say you want to run VPN software they assign you a real IP address?

(Don't get me started on *that* practice... grrr... my Voice-over-IP 
project trying to help newbies through basic setup of these boxes 
sometimes runs into THAT garbage, and it's one of the reasons sited for 
the SpeakFreely project officially going to "end of life" status... and 
it's really hard to explain to people that they didn't get a "real" 
Internet connection from their mom and pop ISP out in the boonies 
somewhere.)

Hmm actually if your friend was FTP'ing stuff from you, that's probably 
not the case...

Oh well... interesting stuff.  "VPN safe"... bah humbug!  :-)

Gimme a real normal boring old standard IP address and let me get on the 
"real Internet" as I've heard it called by some large AOL competitors in 
advertising lately.  (GRIN)
