Xfinity, Comcast, Comcast Business Modem Port Forwarding

 Xfinity, Comcast & Comcast Business 
Modem Port Forwarding

  1. Login to your Xfinity/Comcast Modem by entering one of the two following IP addresses into a browser address bar:
    1. 10.0.0.1 for residential customers.
    2. 10.1.10.1 for Comcast Business customers.

  2. The default logins for most Comcast/Xfinity modems are:
    1. Username: cusadmin Password: highspeed
    2. Username: admin Password: password

  3. After you log in, if you are asked to change the default password, do so! That way no random people can try to gain access to your modem if they gain access to your wifi/network. Use a safe/secure password and make a note of that information for future use.

  4. First off, you want to configure the Firewall in your modem to either be set to Custom or if you can, turn it off completely if possible.

  5. After turning off the Firewall, go to "Connected Devices".

  6. Reserve the IP address (set a static IP) for the device that you are port forwarding to.

  7. Click on the "Advanced" tab, and you can then set up any/all port forwarding rules as needed to your statically assigned device!
