Contact Comcast to Bridge New Modem:

The modem doesn't come bridged for your static IP address. You need to contact Comcast at 800-391-3000 and ask them to bridge the modem for you. There is a Bridge button when you log in but that will render your modem useless if enabled.

2

Log into the new Comcast modem:

Open a browser windows and log into the modem
http://10.1.10.1
us: cusadmin
pw: highspeed

3

Navigate to the Advanced Tab

Navigate to the Advanced tab, then True Static IP Management, and there will be the following checkbox:

Disable all rules and allow all inbound traffic through

Check this box and save your settings. Close out your browser

Test out your ports now

Make sure you are outside the network, and test your connections.
