Disable SecurityEdge / Upgraded service and transparent dns proxying started after modem swap

Hello, my service was updgraded, and a new modem was installed:
     PN: CGA4131COM

 

Since the modem install and updgrade to new service, our DNS is not resolving to those configured manually.

 

No changes were made to any devices on the network other than the service upgrade/new modem.

 

It appears there is transparent dns proxying occurring.

 

I have seen others with the same issue and responses indicating that SecurityEdge needs to be disabled.

 

How can I request SecurityEdge be disabled on my account?

 

Thank you!

Re: Disable SecurityEdge / Upgraded service and transparent dns proxying started after modem swap

Thanks, Robert. Tier 2 support called me back the following day. Though the Tier 1 support person had disabled SecurityEdge, it didn't appear to stick. Tier 2 disabled it, and the DNS issue was resolved. All good now. Thanks!

 

Summary for anyone trying to resolve this DNS this issue:

*Issue*: Modem install and updgrade to new service breaks manual DNS configuration (transparent dns proxying occurring).

*Fix*: Contact tech support and have them disable SecurityEdge. If it doesn't work when Tier 1 disables it, open a ticket with Tier 2.

Update: I called tech support, and they disabled SecurityEdge. It did not fix the issue with my upgraded service having a transparent DNS proxy (hijacking DNS). They opened a ticket with level 2 support.
