This is not a problem, it's a feature ;-) You are preventing X connections (port 6000 and up) to reach your machine. Both by firewalling and by NATting. Unless you use SSH tunneling, there is no way for the X connection to reach back to the machine you telnet from. So either you want connections from B to A or you don't ;-) Lupe Christoph -- | [EMAIL PROTECTED] | http://www.lupe-christoph.de/ | | Big Misunderstandings #6398: The Titanic was not supposed to be | | unsinkable.
