Jeff Pulver, VoIP evangelist, conference planner, and gadget guy, says Las Vegas's free Wi-Fi filters: Ports blocked, me buckos, when you're stuck trying to leave CES. You can do Web, but you can't do telnet, instant messaging, or voice over IP, Pulver writes. There's ugly, ugly weather in Las Vegas right now, and one colleague reports that there's a three-hour line at the airport just to check in.
Set up zebedee to forward over port 80. This requires an Internet-accessible "home" machine running the zebedee server to receive the connection on port 80 and forward the packets to their true destination.
One of the reasons I run ssh on other ports in addition to the standard 22. If you can swing it (ie, aren't running a public SSL website at home), run sshd on 443. Pretty good chance they won't block https.
