Don't need any MAC knowledge there. Router is reporting not being able to reach the internet, it either has no default gateway or cannot reach its' default gateway, which would be the first hop on the VM network.

Router is losing connectivity to the VM network.

DNS settings on MAC are correct if the router is configured to act as DNS proxy which it probably is. Looks to me like the whole 'DNS' thing is a red herring and the issue is simply that the router's connectivity to the Internet is going down.

A failure to pass packets through on the part of the route would result in pings timing out, not network unreachable.

Is it possible to try pinging from the router to the Internet at all?
