This is almost certainly due to a buggy firewall that doesn't understand

firewalls. Do you have one of these in your path?
At home I'm behind a Linux gateway box currently running 2.6.15-rc6 - I
am connected through ethernet to that.
At my student house I am connected wirelessly to a Linksys WRT54Gv5
router (the model that doesnt run Linux).
I have reproduced it at both those locations (same ISP).
This is very familiar, and I just found the article I was thinking of:

I was also hit by that bug, on the same collection of websites, but that
particular problem was fixed for 2.6.8 or so. So I guess it is extremely
likely that my ISP has broken routers. nmap isn't able to identify the
OS of any ISP routers in my path.
It's a huge ISP over here, so contacting them over technical matters is
not easy...
Thanks,
Daniel
