I have one crazy machine at our home office that must communicate on port 6847 to an outside company. This one machine went through our old proxy server until it died last week. We're using IPTABLES through rc.firewall-2.4 on a Linux proxy, but it doesn't seem to be allowing this communication to occur. Would this be handled through port forwarding or NAT? I was under the impression that our firewall was set up to allow all traffic, initated from the LAN, through. This apparently isn't the case, however. Eric
