BGW320-500 issue with own router and security DVR
My parents switched from Xfinity to ATT today.
They have their own router (TP-Link M4R AC1200). It was configured to be 192.168.1.1 and provide DHCP addresses on that network.
After the tech connected the ATT gateway to the router it somehow automatically changed it's LAN IP to 192.168.0.1 which is fine. I updated the static IP on the DVR and updated port forwarding as well to reflect new IP. All ports are same.
ATT gateway is in Passthrough mode
DHCP-fixed and the MAC of the router is selected.
Everything is working except the DVR cameras.
I can't figure out why because the same exact setup worked with Xfinity.
