Arris TM402p modem: How Can I Open ports?

Hi people, i got an Arris TM402P from the first day i started using comcast service, now I want to open a few ports due to my school project. When I go to 192.168.100.1, there is no place for me to open any port. Does it mean all the ports are opened? or all closed? i know the 80 is opened.

 

Please help!!!

 

Thank you

That eMTA doesn't have a router segment. It acts as a layer 2 bridge. There are no "ports" to configure within it.

A modem just passes data back and forth

do you have a router?

So It means I cannot open any port. How can I open the ports I need right now? or just open the ports from my router?

That's correct. This needs to be done in your router and any software firewall that you may have installed on your computer. The modem is a transparent bridging device.
