How do I set up my daisy chain of routers?

[061]

The other day I bought two new ASUS RT-N56U Duel Band Router. I have one router (Router 1) wired from the modem into it's WAN. In the first port of Router 1 I have wired in my second router (Router 2). The internet is coming through fine. Or so I thought. When on CoD Ghosts, I noticed my NAT type was "moderate" instead of "open" as is was before. This will hamper my connection to many other players. I need to know how to configure my routers for optimal gaming. I would DMZ, but i have my PC, PS4, and PS3 connected to Router 2. I need all machines to not be hampered. This includes any devices connected to Router 1. Please provide clear instructions (routers are NOT my thing) on how to set up my routers to allow the best possible wired connectivity. More information can be provided if needed. Thanks.

Totally incorrect configuration. NEVER use more than one router on the same network. It slows it down. It also causes many other problems like the one you have. It can cause disruption or even total loss of service at times. There is never any need for a second router on a normal home or small office network, whatever your problem was there would always have been a better method. Might have been better to ask advice on what you SHOULD have done first.

You can use many routers - the whole Internet is made of routers all connected to each other.
The key is to make sure each router has a separate, different subnet from the others. Also, if running games that require NAT, with two or more routers, you have double NAT. In some cases, you may need to open up the first router (closest to Internet) with either a DMZ to the second, or do double port forwarding - first router forward to second router, second router forwards to PC....
Problems come about when multiple routers are not configured properly. I have 3 or 4 routers on my service (but I do have multiple public IP addresses). I've run 3 routers in a row at times, it all works 100% if done right. There is no speed difference either. Most of these people saying you can't, just don't know how, or are simply propagating "urban legends" about what works or not...

However, if you are not sure how to set up multiple routers, get some help from someone who knows networking...

Basically think of it this way, each router is a Internet service, and your next router has to pretend it is next in line, and has to be unique in its config. A ISP connects to your modem via a router, with their IP address. Your first router connects to that. the second router, has to think of the first router as the ISP router, and you need to make sure it is configured properly...
