![]() ![]() Do you have a default gateway and DNS servers specified in the ipv4 settings? I assume so, since you mentioned 8.8.8.8. ![]() If you think the guest and host are communicating correctly, perhaps its a configuration problem between the host and the other router that is causing the problem. You probably tried all this already, but I thought I'd throw whatever ideas I have your way really quick to see if anything sounds worth trying. If the purpose of using NAT is to provide firewall functionality between the guest and other devices on the LAN, then would a standard "allow out, deny in" firewall configuration on the guest work as well? That being said.I can't help but wonder what advange there is in having the guest behind NAT when the rest of your local network is already behind NAT. You obviously sound very experienced, and I personally find it annoying when someone asks a really specific question in a forum, and someone answers that question by suggesting they do something totally different that what they want to do. ![]() Some people report this as resolving the issue, at least in the short term. You can still configure and use firewall features of the guest (iptables, ufw, etc) to limit access to and from the guest if you want some control. However, if you want the VM to be able to interact with your entire network you should stick with bridged. ![]() I would suggest NAT if you want to limit the connectivity of the guest, while still allowing for networking between the guest and host only. Your host in this case is a NAT firewall between the guest and the rest of the network. In order for other devices to communicate with a VM set to NAT, the host system would have to perform port forwarding to translate the IP just as your gateway/router would have to port forward to allow computers from the WAN to communicate with your LAN. NAT is sufficient to provide internet access to a guest, but you're only going to be network between the guest and the host, or other guests on the same host's NAT network. If you want the VM to be able to access and be accessed by different devices on your network as if it were a real decive, then bridged mode is the way to go. ![]()
