Anybody with this problem is kindly invited to try to connect to 213.244.168.210, port 10000, http://213.244.168.210:10000/ should work.
If you have a problem, email me with your IP address, I have a tcpdump running.

The remote is in fact zeus-pub.kernel.org. I assume it does not have a broken firewall, and I sure haven't, and it sends out to me:
00:46:31.936667 192.168.1.4.34018 > 204.152.189.116.80: S 2786942165:2786942165(0) win 5840 <mss 1460,sackOK,timestamp 269093190,nop,wscale 7> (DF)
00:46:32.097745 204.152.189.116.80 > 192.168.1.4.34018: S 2888442437:2888442437(0) ack 2786942166 win 5792 <mss 1460,sackOK,timestamp 3563902477 26909319,nop,wscale 0> (DF) ^ 00:46:32.098170 192.168.1.4.34018 > 204.152.189.116.80: . ack 1 win 45 <nop,nop,timestamp 26909481 3563902477> (DF)
So I would rule out 1), as this is a network that does not have the problem.

This looks more likely, on the outgoing SYN. We'll know tomorrow evening (CEST) or earlier if somebody with the problem volunteers.
