SuSEfirewall2 does not have such a mechanism and TBH I pretty much dislike the idea of allowing applications to inject arbitrary rules. I'd prefer some higher level abstraction so it's left to the firewall to decide how to translate the request into actual iptables rules (or whatever else technology is used in the background). cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
