I would like to connect a second Router to the CISCO Gateway DPC 3825 to have two separate networks. (Office / Kids).


I don't want a bridge.


Router 1 / Cisco DPC 3825 / IP


DHCP: on

Two Computers wired connected: and


Router 2 IP: fixed IP


Router 2 / TP-Link ER 604W / IP:


DHCP: on

NAT: on


DNS Server 1:

One Computer (Computer 3) wired connected:

The Cisco Gateway is wired thru the LAN port to the WAN port of the TP-Link Router.


I can ping from Computer 3 (via Router 2), Computer 1 & 2 (which is correct) but I can’t connect Computer 3 to the Internet.

Any idea ?

Maybe I need to put a cloned MAC on Router 2 ?
