How to Configure a Linksys E-series router to function with a Grandstream
Please follow these instructions to configure a Linksys E4200 router to work with the Grandstream. These instructions are only if you are connecting the Grandstream to one of the numbered ports on the Linksys router.
First, turn off the power to the Grandstream. The router can stay powered on.
Connect an Ethernet cable from one of the numbered ports on the router to the WAN port of the Grandstream.
Power on the Grandstream.
Next, Enable WAN port web access to the Grandstream. Please refer to Enabling WAN port web access on the Grandstream.
Connect your computer to the Linksys router and log in.
Open your browser and in the address bar type http://192.168.1.1 and press enter.
The default username is admin.
The default password is admin.
Once logged in, click on Security.
- NOTE: These are the default settings for this router. If these donn't match and you do not know the address, username, or password, please contact whoever set up your network and ask them to provide your this information. Once confirmed, please store the information in a safe place.
Click on both of the radio buttons next to Disabled and click on Save Settings.
Click on Continue.
Click on Applications and Gaming.
Click on Single Port Forwarding
