I am not using VNET, jails are aliased directly in host's network > interfaces (lagg0 for HOST1 and em0 for HOST2). Let me guess, lagg0 includes a wireless device? I think you may have the issue that you can not run multiple MAC addresses on a wireless device, and each of your jails on this node are going to have a unique MAC. > Thanks > GrzegorzJ > > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > -- Rod Grimes rgrimes@freebsd.org
