It requires exactly one 'internet' device and one 'local' device. It is possible to make eth2:1 work by manually inserting a couple of rules in iptables, but they eventually get overwritten the next time firestarter is started. In principle, I could make a cron job check iptables periodically and insert the rules if necessary, but that would be too ugly hack. Ping works because iptables are set to be transparent to icmp packets. At this point half of the configuration I made on the machine is useless since httpd, dhcpd and named are not able to go through the eth2:1 device, and I need to rethink the design of the whole thing. Or give up firestarter, master iptables skills and tweak them manually every time (which is equally painful)... Oh, well... :-( Best regards, Marko -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
