Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

New to this. Installed Norton Core last Friday.  Every day multiple times a day PC on Cisco 200g -26 switch lose internet connectivity.  Have tried changing DNS multiple times. Very frustrating.  ISP <==Arris<==Core<==Cisco 200g<==PCs.  This did not happen and does not happen when the Core is removed from the equation.  It also did not happen when ISP <==Arris<==Netgear R6300<==Cisco 200g<==PCs

Any relevant comments appreciated.

Re: Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

Hello Joe He. Welcome to the forums. Your configuration for the Core is totally incorrect. The optimum setup is using an ISP device in bridged mode. The wifi capabilities and DHCP routing turned OFF, IF, your ISP device does not require DHCP enabled on it for TV/VOIP services. If you can setup your Comcast device in bridged mode so it may function as a pure gateway per the article below.

When done power down your Arris TG1682. Connect the Ethernet cable that came with the Core to the Arris per the bridged instructions. Connect the other end to the port with the blue globe icon under the Core. Fire up your phone app and follow the screens instructions.

Note: The Cisco 200g -26: This should be connected to one of the LAN ports on the bottom of your Core router. NOT your ISP router. Anything downstream can then be setup on your Cisco switch and Core will protect it.

Hell again. Following up on the thread to see of our suggestion helped. Can we assist further?

My issue with the above is that I work from home and it is mandatory to use CISCO vpn for work and an Avaya VOIP system. When I tested earlier neither of these would work attached directly to the Core.  I will try this again tonight.

Re: Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

Hello again Joe He!! This is your Comcast device from the model you gave me. Firstly make sure DHCP REMAINS ENABLED on this device to support your VOIP phone services. The Avaya should connect at the top (2 phone jacks). Next the Core Ethernet cable should be in one of the LAN ports in the Ethernet area, the other end to the core port underneath with the blue globe icon. Your Cisco smart switch should connect as I said before to an Ethernet port under the Core so that it becomes a protected part of your network. Your downstream devices connect wired through the smart switch or wireless on the Core. This is the setup I would use in your situation.

Cheers

Re: Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

Ok tried this last night.  2.5 hours later still a failure.  The one thing I did not try was having the Core Router as the only thing plug into the Arris.  I have an Avaya VOIP phone for work and that was plugged in as well.

Re: Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

Joe. The Core SHOULD be the only thing connected to your Arris modem. Plug the core Ethernet port into LAN port 1. Connect everything else to the Core's three Ethernet ports to go down stream. Your Avaya goes into the phone ports on the modem unless it requires Ethernet which I am not sure of since I don't know the model you are using. Your setup is straight forward and simple. Setup the core WITHOUT anything connected to it. Just the Arris modem and Core. Tell us what your results are.

Re: Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

Thanks for your help with this issue.  I appreciate your input.  The Avaya VOIP phone plugs in to an Ethernet port.  In the past, the phone could not establish a VPN when a previous netgear router was between the phone and the gateway.  I will test this all again, if the phone can not establish the VPN I lose critical functionality for work, which is 100% stop for me. I will test with it connected to the switch later this week and I will start with nothing connected to the Arris except the core and nothing connected to the Core.  Your suggestions make sense to me, although Norton support wants me to wait on what their engineering dept. recommends.

Re: Norton Core & Cisco 200g -26 & Comcast Gateway Arris TG1682

Thanks Joe. The Avaya can go into one of the other Arris LAN ports. Connect it there AFTER setting up the Core. Keep in mind the app will tell you that you are connected to a second network so just ignore that and continue with the setup. Your security score is just that. We have to get you functional first then help you get that score as high as possible.
