I live in a building that provides internet to residents. Their server room consists of a cox ISP modem connected to a series of routers and switches to supply internet via ethernet in each apartment.

I have a Router (ASUS TM-AC1900) that I would like to use to create a private LAN. Currently, I have the ethernet cable from the server room connected to a LAN port in the router which allows me to create a wireless network. However I don't like that I am on the same network (192.168.1.x) as everyone else where they can see my devices. Right now anyone can cast videos to my xbox one on the network and it will play automatically and I can do the same to other devices I see.

What I would like to do is connect the ethernet cable from the server room to my router's WAN port to create a separate private LAN (192.168.2.x). Please correct me if this is wrong, I'm only average with networking. How can I set this up without access to the main router's DHCP settings?

Thanks you were right. The router was assigned 192.168.1.221 and my router's LAN IP is now 192.168.21.1. It appears that I have achieved what I needed here.

Now I've run into another issue. Double-NAT. How can I resolve this so I can get DDNS service to work without access to the main router?
 


You cant. :(

I was able to accomplish this by setting up a VPN connection and installing a Dynamic Dns client. I can now access my computer externally.
