Step-by-Step Configuration

• Change the default password for security.
• Set up the WAN interface to connect to your internet service provider.
• Configure the LAN interface with a suitable IP address range.

Step 6: Setting Up Multiple Separate Networks

To create multiple networks:

1. Navigate to Interfaces > Assignments.
2. Click on the "+" button to add new interfaces.
3. Configure each interface with separate network settings according to your requirements.

Practical Tips

• Use VLANs for better traffic management if your hardware supports it.

Step 7: Firewall Rules Configuration

Setting up firewall rules is crucial for securing your network:

1. Go to Firewall > Rules.
2. Add rules for each interface to control traffic.
3. Ensure to allow necessary traffic while blocking unwanted access.

Common Pitfalls
