Failover IP address question

We recently upgraded our Comcast speed and as part of the upgrade got the broadband failover unit.  The Comcast modem connects back to our SonicWALL firewall which needs to have a public IP address on the WAN port.  It doesn't have to be static but it does have to be the current public IP.

If the Comcast network goes down and it switches to the failover, will the failover's public IP get presented to the firewall?  The tech wasn't sure so I asked him to not connect the unit until I could get a definitive answer.

Hello and Happy Wednesday! I hope you’re having a great week so far! I also appreciate you taking a moment out of your day to reach out to us on our Community Business Forums! You’ve reached the best place and perfect person to help with virtually all of your account needs! Going forward, the failover second public IP should become presented to the firewall in this scenario however, you might have to consult with your SonicWALL support team to determine if additional DNS settings are needed to convert the new public IP address being presented. Hope this information helps!

The SonicWALL is set up for Dynamic DNS so it will pick up whatever public IP is presented to it and then should work fine with a failover.

As a related question, and I'm not onsite to check this out, is there a document available that shows how to connect the failover box to the Comcast modem or do I need to schedule a tech visit?  He left the equipment in place but just didn't hook up the failover.

Ok, cool! As long as SonicWALL is set up for Dynamic DNS, the second public IP should work just fine with your fire wall. You can also learn more about our Connection Pro settings and management here: https://comca.st/31VKWde. Please let me know if you have any additional questions and thanks again for your time!

The tech left the Connection Pro device disconnected, as per my instructions to him.  Is hooking it back up something a user can do or do I need to place a service call?

I'll be onsite in a few days and will check it out.

Ok, gotcha! To be honest, it should not be too difficult to activate using the link I provided above since it sounds like the equipment is installed just disconnected however, to play it safe, we can also set up a tech appointment as well. It's completely your call!

The Cradlepoint is showing in standby mode which I take to mean that it is installed and activated.  However we had an extended outage a week ago where it didn't kick in so I believe the tech did not make a necessary connection between it and our modem.  I should be onsite next week to see what cable might have been left disconnected but was hoping there was some sort of setup manual I could review.

If I can't figure it out, I'll place a service call.

That sounds like a plan. If you need us to assist when you are on-site or to set up a tech visit, you can click on the little chat message bubble icon in the upper right and send a private chat to "Xfinity Support" with your name, the business name, the complete service address (including city, state, ZIP, suite number, etc), and the phone or account number so we can help :)
