What This Template Offers
A fully structured physical network diagram covering ISP connectivity, firewalls, switches, DMZ servers, internal LAN devices, wireless access, and endpoints — ready to adapt to your environment.
- Pre-built hierarchy from Internet/ISP down to individual workstations and printers
- DMZ and internal LAN segmentation shown with dedicated switches
- Distinct node shapes for routers, servers, switches, access points, and endpoints
- Wireless access point with connected laptop for modern hybrid networks
- Zoom and pan enabled for exploring large or complex network layouts
Use cases
Perfect Use Cases
Network Security Review
Visualize firewall placement, DMZ boundaries, and internal segments to identify exposure risks and plan remediation.
Office or Data Center Planning
Plan cable runs, switch placements, and device layouts before deployment to avoid costly mistakes on-site.
Troubleshooting and Incident Response
Quickly trace the path from a failing device back through switches and routers to isolate the root cause of network issues.
Customize
How to Customize
Add or Rename Devices
Replace the placeholder node names with your real device names, hostnames, or IP addresses to match your actual infrastructure.
Adjust Network Segments
Add additional switches, VLANs, or server groups by inserting new nodes and drawing connections between them in the relationship editor.
Set the Root Node and Export
Choose your core router or main switch as the root node to center the layout, then download or embed the finished diagram for documentation or presentations.
Key Benefits
- Saves hours compared to building a network diagram from scratch
- Clear visual hierarchy makes complex topologies easy to understand at a glance
- Works for networks of any size — small offices to enterprise data centers
- No specialized diagramming software required — runs entirely in your browser
Pro Tips
- Use the 'cloud' shape for external nodes like the ISP or third-party services to visually separate them from internal infrastructure.
- Group servers by function (DMZ vs. internal) using separate switch nodes to make security boundaries immediately obvious.
- Enable zoom and pan when presenting to stakeholders — it lets you drill down from the full topology to individual device details without switching views.
