[PVE-User] quick urgent question re vlans in proxmox

[Lindsay Mathieson]

We run all our windows dev, test and production servers on our proxmox 
servers, weekly onsite DR backups and monthly offsite DR backups.

And we just got hammered with a root kit virus that is proving extremely 
difficult to remove.

I'm proposing that we restore one by one from last month DR backups to a vlan 
tag of 1, check thats its clear, then change it to a vlan tag of 2.

As you may have guessed, I'm a complete novice when it comes to stuff like 
vlans.

- Is it sufficient to just set the vlan for a VM via the proxmox network 
device gui? 

- will that isolate it from the main (infected) network?

- can I keep the same subnet? (192.168.5.0)

- Will the VM's be able to access the outside internet?

Thanks,
