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?
