dnLL Posted June 3, 2019 Share Posted June 3, 2019 (edited) Hi, Just looking for the easiest approach here, I created a VM with virbr0 in unRAID so it's sitting in the 192.168.122.x segment which is fine. However it can still ping my LAN IPs including unRAID, but not the hostnames. Now, I would like to prevent that, since that VM is for testing purposes and I don't want it to propagate through my network. I'm aware I could mess around with my router to get the work done, but I was wondering if I could just use unRAID's iptables to make a rule to block local connections to the rest of my LAN. Since such a rule would indirectly prevent the VM from accessing its host, I'm thinking it would be safe enough for most purposes? I have no experience at all with iptables, so excuse my ignorance if such a solution is either impossible or not safe at all. Edited June 3, 2019 by dnLL Quote Link to comment
