I have been successfully using X protocol across an ipchains gateway. I am trying to move to iptables. Finally ,and thanks to some help that I got at this forum, everything is 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 does or does not supports X. Thanks Reuven __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com
