The following is nmap output over Megabus-provided wifi (en route to Boston) showing the proxied ports.

What’s sort of annoying is that:

1. Port 22 (ssh) is blocked.
2. ICMP Time Exceeded messages are blocked (not shown), making tracepath unusable.

I will be attending the Linux Plumbers Conference and the Beer Advocate Belgian BeerFest in the coming days. More on those as they happen.
