Medium firewall setting is stopping X display for remote clients
I am a Linux newbie. I have just installed my system with the 'medium' security setting. I am wanting to run a program on an X client and display the graphics on my X server. It seems that my security setting is stopping this. I do not want to run without a firewall. I would be grateful if somebody could tell me how to customise the firewall so that I can connect successfully to an X client.
