Man, I thought this was old news (hence why I didn't think of it) but I
guess not.  Looks like there are still some devices out there that don't
like the ECN TCP flag.

In a nutshell, with the defaults in the 2.6 kernel, the ECN TCP flag is
causing all sorts of issues with packet inspectors (firewalls and/or
1-to-many NAT devices) as well as some routers.  Disabling it quickly
and effectively solves the issue.

Touche on the suggestion.
