I have no problems updating several Windows machines behind a Mandrake machine with iptables. I do NOT have squid running, and only run the standard iptables suite vs. the canned Mandrake firewall. I do not believe this is an iptables issue, but perhaps something else Mandrake has done with their firewall setup. My rules are very simple, and were obtained by following the tutorial from Oskar (http://iptables-tutorial.frozentux.net/iptables-tutorial.html) I go back to this document often, and seem to glean something new from it each time. (Thanks Oskar!) You shouldn't have to have any ports open, but should use snat from the internal machines to your external ip address, and dnat from the external ip address to the related,established ports. That should be it. -=Ray --------------------------------------- He who gets excited in fighting is sure to make mistakes.
