Good evening,
Is it possible to send Router 1 DHCP (from Router 1’ LAN Port) over a VLAN to Router 2 (into Router 2’s WAN port); so that Router 2 can obtain it’s WAN using DHCP?
The Problem:
Router 1’s DHCP goes over a coaxial cable that is being used by the TV modem so Router 1’s DHCP is being ‘overshadowed’ by the DHCP of the TV modem, so I wonder if a VLAN can be created between the two routers so Router 1 can send the DHCP to Router 2 over the same coaxial cable being used by the TV modem.
Thank you,

Does your modem/router not have a bridge mode?
Hi Maximus,
The TV modem is in bridge mode and cannot be disabled, I think it’s multicast.
See my recent thread below: Two Broadcasts - One Coaxial Network.

You have your terms mixed up. Do you have a diagram of how they are connected? Where does the first device come in to the house that contains your connection to the outside? Do you have access to modify either of these two router devices?
In short, yes you can have DHCP1 device give an address to a second downstream router to route the second network, I did this in my lab to test creating a second LAN DHCP scheme and it needed internet to activate the eval version of the OS.
