[ale] VPN connections at Emory

The TOS at most institutions forbid guest access to wired ports.  But, we won't mention that.  I don't know about this specific institution.

Un natted connections sound a bit disturbing.  I would think the whole institution would be running on a giant nat.  Even so, I think a Windows machine should be OK as long as the OS firewall was running.

Re VPN, I was running hotspotvpn on Windows the other night at the meeting on the wireless.  I was using HTTP protocol as far as what the menu says.  I assume it was using SSL on 443.  I think it runs OpenVPN under the covers.  It was working fine.  When I ran speedtest.net to test it, it showed my data exiting the tunnel in California.  Not the most efficient, perhaps, but it worked.  They have a linux option, but I haven't gotten that working yet.

Sincerely,

Ron
