I have been successfully using X protocol across an ipchain gateway. I am trying to move to iptables. Everything is finally working smoothly except for X. I am bypassing masquerading when my source/destination are the X client/server so that I can use my non-masqed ip address for the 'display' parameter of say xterm application.Could anyone tell me if iptables supports X and if so how. One more general question: Is there a way to trace packets to see what goes in and out of the iptable/netfilter gateway? Thank you in advance __________________________________ Do you Yahoo!?
