Linksys WRT300N: GUI
The GUI tab offers the same configurations and settings as the Config tab with some additional features for port forwarding, management, as well as router and network status. Make sure you click on the Save Settings button at the bottom to apply the new settings to the Linksys WRT300N.
Setup Configuration
In the Setup tab under the Basic Setup sub-tab, you can set the Internet Connection Type to either automatically obtain IP configurations with Automatic Configuration - DHCP or you can manually set IP configurations with Static. You can also set the LAN IP configurations and DHCP settings under the Network Setup section.
Wireless Configuration
In the Wireless tab under the Basic Wireless Settings sub-tab, the only setting you can change is the Network Name (SSID). Under the Wireless Security sub-tab, you can set the Security Mode to either Disabled, or you can enable WEP security mode and then set a key in Key1 for WEP authentication..
Applications & Gaming Configuration
In the Applications & Gaming tab under the Single Port Forwarding sub-tab, you can forward packets destined to specific ports to an IP Address. To forward a port, select the appropriate application under the Application Name drop-down menu, enter the IP Address under the To IP Address column to which you want the packets to be forwarded, and then click on the box under the Enabled column to enable it. To forward a custom port, enter an application name and then enter the appropriate Externet Port, Internet Port, and Protocol. The Externet Port is the port to which the Linksys router will listen from the WAN side. The Internet Port is the port on your local server to which the Linksys router will forward packets.
Administration Management
In the Administration tab under the Management sub-tab, you can change the default password to access the router through the Linksys Web Configuration using the Web Browser on the PC. You can also toggle Remote Management.
Status
In the Status tab, you can view various Router, Local Network, and Wireless Network information under the respective sub-tabs.
