A detailed look at the networking that runs the CIS room.
Quick Overview
Line from street ---> Comcast Modem at Hackler Gym ---> Netgate Firewall ---> Mikrotik L3 Core Switch
The Mikrotik L3 Core Switch divides the network into 3 VLANs:
| VLAN ID | IP Address Range | Router Address | DNS Server | Name - Purpose |
|---|---|---|---|---|
| 5 | 192.168.5.0-255 | 192.168.5.1 | N/A | Intermediatry network to Lab VLAN |
| 20 | 192.168.20.0-255 | 192.168.20.1 | 192.168.30.2 | Class - Regular Class network, do not mess around here, regular class activities should not be interrupted |
| 30 | 192.168.30.0-255 | 192.168.30.1 | 192.168.30.2 | Server - All long-term servers are here, NEVER mess around here |
The Class VLAN is where all of the Work PCs are connected.
The Server VLAN is where all long-term Server Overview's are connected. They
| VLAN ID | IP Address Range | Router Address | DNS Server | Name - Purpose |
|---|---|---|---|---|
| 5 | 192.168.5.0-255 | 192.168.5.1 | N/A | Intermediatry Network to Lab VLAN |
| 10 | 192.168.10.0-255 | 192.168.10.1 | 1.1.1.1 | Lab VLAN for messing around |
The Lab VLAN is designed to be independent from the rest of the room, where students can work on projects with little to no consequences. It is completely isolated from the rest of the room, and cannot communicate with anything except for the internet.
