Which pretty clearly shows that it's not linuxforums.org blocking you.

Of course, it could be your packet filter causing the problem. My guess
would be, it very likely is.
What exactly does "have some ports blocked" and "blacklist policy in
effect" mean?

What is the output of
sudo iptables-save
?

BTW: some posts ago, I asked you whether there's a packet filter active
on your machine. You answered "no". How come?
