Comcast Business Bridged Static IP's inbound ports seem to be blocked.

This is a new install, moving from Century-Link's T1 Internet to ComCast Business Internet service.  Setup includes 5 usable bridged static IP's.

 

Inbound traffic seems to be blocked on ports 443 and 22 on each device connected to the Comcast-netgear 4-port switch.  Outbound is working as expected and shows the proper static ip's as configured.

 

Any clues to releasing inbound traffic will be gratefully received...

 

Thank you,

Hello JeffAtPac, for the protection and security Comcast does blocks some ports (here is the complete list).

However port 443 and 22 are not block by Comcast.

 

 

Thank you.

Thanks, Jon.

 

Is there anyone at Comcast that I can ask to help me trouble shoot our new service?   What's the best method for seeking this kind of assistance?

 

Thanks again for your prompt response.
