We recently subscribed to Verizon FiOS Internet service. We have an existing CISCO router which is used to establish Tunnel to our main network at different location. We can connect the FiOS connection directly to our CISCO router, but we need to use cable output (to connect TV) from Verizon Router.
The Verizon Tech suggested me to config the Verizon Router by changing the necessary DHCP to match with our internal CISCO router. So that it will keep us in the same internal network.
I've the necessary details for both Verizon FiOS Router and our existing CISCO Router (IP, Gateway, Primary and Secondary DNS.)
I don't know exactly what changes that I need to make in Verizon Router to accomplish this. Can anyone guide me on this? Thank you.
