-### Network Modeling: Segmented Lab access with Containerlab and ZeroTier

-When building out network labs, often multiple people will need access to the lab. The main way right now is to use something like EVE-NG or GNS3 to provide access.
-
-There are 2 downsides to this method. The first is that your server is exposed to the internet and if your usernames/passwords aren’t strong enough, your server can become compromised. The second is that sometimes you may not want everyone to be able to add or edit to the lab topology.
-
-The solution to this is using Containerlab and ZeroTier. This setup is great for things like testing new hires, training classes, or for providing lab access to others on a limited basis.
