Second IP Address needed for SB8200

How do I activate the second Ethernet port on my SB8200 modem?  I understand I need a second IP address.  I called customer service and they were unable to help!  

 

Is this available for my area (Lake Zurich, IL)??

Re: Second IP Address needed for SB8200

First, check the "Rate Card" for your local area to see if that feature is even available anymore. Seems that it is being phased out;

 

https://www.xfinity.com/support/rate-card/

 

It's a PDF.


Scroll down to "Xfinity Internet" and look for "Additional IP Addresses".

 

If nothing is listed then it's likely to have been discontinued in your local market area.

Unfortunately no its not.

 

Im in Gurnee

 

That second ethernet port is supposed to be used for LAG aggregation 2Gbps and is controlled via firmware..

I have never actually subscribed to the 2Gb tier and when I asked about it.  I had a spiel about how they need a professional come out to install.  smh...

Thanks for the update.  This is disappointing.  I wanted it for direct ethernet connection to my computer with vpn.  

 

When I use vpn thru my switch speed is dramatically lower...hoping second port would allow me to bypass switch.

 

If anybody has another idea let me know

FYI, the 2-gigabit speed tier (Gigabit Pro) is not delivered via DOCSIS (coax cable). It is delivered via FTTP / FTTH (Fiber To The Premises). And it indeed requires a professional install, and that's if it is even available in one's local area.

With that being said.  the second port on the sb8200 may never be used.  Even though thats what it was designed for..  It looks like they are starting to release modems with a 2.5GbE port. for support higher then 1GB.  Its only a matter of time, or decision making on xfinity to utilize them.  The XB6 has two ports but the second was designed to be used with the HOME security equipment.

They would need to free up enough TV bandwidth in order to implement another super wide DOCSIS 3.1 / OFDM channel to be able to offer another gig of speed.

 

And their security system interfaces  with the XB6 via a hidden WiFi broadcast.
