First of all I must to clarify that I'm newbie in networking and there are some thinks that I don't understand in your message, but, I will do anything you ask to resolve the problem, because I think this is a bug in the wifi firmware that I'm using (please read the reply sent to Tom). I'm running the default config, I have not modified anything related to the network. I will paste here the config file output and the command output. This is in my pf.conf:
# $OpenBSD: pf.conf,v 1.54 2014/08/23 05:49:42 deraadt Exp $ # # See pf.conf(5) and /etc/examples/pf.conf set skip on lo block return # block stateless traffic pass # establish keep-state # By default, do not permit remote connections to X11 block return in on ! lo0 proto tcp to port 6000:6010 this is the output of that command: block return all pass all flags S/SA block return in on ! lo0 proto tcp from any to any port 6000:6010
