Detailed LAN Network Configuration Guide

A LAN (Local Area Network) connects devices within a limited area, such as an office or home. The WifiSocks Router provides flexible and secure LAN network management features.

Essential Concepts to Understand

Parameter	Description
DHCP	The protocol for automatically assigning IP addresses to devices connected to the LAN, simplifying IP address management.
DHCP Start	The first IP address in the range to be assigned by DHCP. It should start from 2 to avoid conflicting with the router’s IP address (gateway).
DHCP Limit	The maximum number of IP addresses that the DHCP server can assign. When this limit is reached, new devices will not be able to connect to the LAN.
DHCP Lease Time	The duration an IP address is reserved for a device. After this time, if the device is no longer using the IP, the address is reclaimed and can be assigned to another device.
Prefix Length	The network prefix length, which determines the number of available IP addresses in the LAN. A larger value means fewer available IPs. Example: /24 allows 254 devices, /28 allows 14 devices.

LAN Network Management

Open the router’s admin page, navigate to the “Router Configuration” tab, and click the “Manage LANs” button.

LAN Network List

Displays a list of existing LAN networks on the router.
Track detailed information: DHCP configuration, subnet, and the network port in use.

Update LAN Network

Select the LAN network you want to update.
Click the “Update” button.
Change the parameters: IP address, prefix length, DHCP settings (start, limit, lease time), and Private LAN MAC.
- IP Address:
  - Enter an address belonging to one of the following two subnets: 192.168.0.0/16 or 172.0.0.0/12.
  - Example: 192.168.1.1
- Prefix Length: Change or keep the default value of 24.
Click “Update LAN Network” to save the changes.

Add New LAN Network

Click the “Add LAN Network” button.
Enter parameters similar to those used when updating a LAN network.
Select the physical LAN port to be assigned to the new LAN network.
Click “Add LAN Network” to save.

Delete LAN Network

The WifiSocks router’s default LAN network cannot be deleted.
To delete a LAN network assigned to a physical LAN port, click the “Delete” button.

Usage Recommendations

Security: Change the router’s default IP address to enhance security and anonymity.
DHCP Lease Time:
- For short-term connections: Decrease the lease time to prevent IP address exhaustion, which would block new devices from connecting. Use the formula: Estimated connection time divided by 2. For example, if a device disconnects after 10 minutes, set the lease time to 5 minutes.
- For long-term connections: Increase the lease time (30-60 minutes) to reduce the load on the DHCP server.
Device Isolation: Enable the Assign unique Router MACs per device function and create a separate LAN network for each physical LAN port to optimize device isolation. Also, enable the network isolation feature.

Troubleshooting

Cannot access the admin page:
- Check and use the router’s new IP address.
- How to find the gateway IP address:
  - Windows: View network information at the Network icon in the bottom-right corner of the screen.
  - Android/iOS: In the Wi-Fi network settings.
Device is not receiving the new LAN IP:
1. Disconnect and reconnect the device to the router.
2. Open CMD and use the commands ipconfig /release and ipconfig /renew on Windows.
3. Restart the device if necessary.
Cannot connect additional devices to the router:
1. Check the DHCP settings (Start, Limit, Lease Time).
2. Reduce the lease time, reduce the starting IP, and increase the limit to increase the number of assignable LAN IP addresses.
3. Use a lower prefix length, e.g., 22 (total number of IPs will be 1024).

Note: If the issue persists, please contact technical support.
