Windows 7: Help configuring my home network.

Help configuring my home network.

I have very little knowledge of networking. I have had configured my home network with the help of online guides and tutorial and mainly by hit and trial, last year and it performed successfully. It may not be perfect but it worked and this is how it has been working.

Setup1.
ADSLModem provided by ISP (PPOE 192.168.1.1 and subnet mask (255.255.255.0) DHCP enabled range (192.168.1.50 to 192.168.80) and default DNS by ISP. UPNP enabled (but nothing configured here and in NAT as well, as things were working fine so I never touched it) Wireless (OFF)
NOTE, I can't tell if my ISP registers Mac of this modem to authenticate the services)

Setup2
LinksysWTRG router with DDWRT 2.4 installed with auto 'configuration DHCP' (guess this enables connections from the SETUP1 for WAN, hence IP 192.168.1.50), subnet mask 255.255.255.0, gateway 192.168.1.1 and DNS 192.168.1.1. LAN setup; ip 192.168.2.1
Subnet 255.255.255.0, gateway 192.168.1.1. DNS by UnblockUs.com to access Hulu, Netflix etc outside U.S. NAT services and UPNP enabled with nothing specifically mentioned to forward the services to.
Wireless enabled. And DHCP Server enabled for LAN IP 192.168.2.100 to 192.168.2.130.

Setup3
16 port switch that is hosting Roku, Bravia LCD, 2 NAS and a windows seven Laptop wired. All the devices on the switch are connected to Setup 2 through wire and wireless, like iPhone, iPads etc.

Setup4
TpLinkRouter set on Dynamic Ip configuration with auto Ip for wan and 192.168.2.20 for LAN. With subnet 255.255.255.0. And DNS auto. Devices connected to this are PS3, WDTvLive and Windows 7 64 bit a Ultimate desktop and a couple of iPhones and an ipad.
Windows seven is hosting Plex media server, and utorrent like softwares and PS3 is obviously for online.
Please note I have always recived 'NAT' problem while playing online but speed has never become a problem. Plex media server hooked with Setup4 always connects to NAS on Setup3.
This way I have been able to watch any of my media at any corner of house on wire and wireless.

This whole setup worked pretty good for more than a year and now I am feeling bad that I broke it just to make Plex media server accessible to me on my trips to other cities. I read the articles from Plex support and encountered that I had a 'Double Nat' problem and thought I could fix it by trying to make a little changes. It's been three days and I am getting frustrated. Nothing is working. Good thing I have back up of all the router settings. But I want to fix this once for all.. If everything still fails by Sunday I am going back to my old setup and compromise accessing my media server outside my network. Huh.

Now the Setup looked like this
Setup1 [from LAN] to Setup2 [to WAN] to Setup3 [Switch connecting all the devices of Setup3] and ---> to Setup4 ( Tplink Router(Cat5 or 6 from switch to LAN port) this router is at different floor) to all the devices of setup four.

What I am trying to do is turn Setup1 into a basic modem that will only handle internet connection without any DHCP, firewall and UPNP Nat leaving these for router at Setup2 to handle. It should have been pretty simple. Isn't it ?
I seriously think I am making some mistake in assigning IPs and Subnets. Want to keep the IPs assigned already from the setups above. I also didn't and don't want to change how everything is connected through either net on assigned ports.
Or must I ?

I am guessing my problem lies in Subnets. Because each time I assign an ip or subnet on any modem or router one thing or other stops responding. By responding I mean they stop seeing see each other. Please let me know if this is the way. Help me fix this and if you think I am getting it all wrong please advise another method.
Please note I cannot go all wireless due to some reason.

Let me know if left out any other details.
Ciao.

I had various routers at home too, and what I did is change the dns for each that way the don't get into any conflict
ie
router 1 - 192.168.1.1
router 2 - 10.10.10.1.1
router 3 - 20.20.20.20
that also helps to track down what is connected to what...

on the other hand also have you just tried to get a "manage router" so you can perhaps change vlans in within...

Thanks Ivanjrt. As I said I have very little knowledge about this. But keeping track of what's connected to which router wasn't a problem and it was easy anyway. Everything was on Setup2 actually which was acting as the DHCP the Setup3 was just working as a hub. So every device was on 192.168.2.X.

Can you please explain how would this help my case?

Do you mean these two 10.10.10.1.1 and 20.20.20.20 are the IPs ?? Manually assigned to router 1 and router 2

hmm, perhaps I am confused, in what your network might be, can you draw a topology of your network against your goal?

Help configuring my home network.-imageuploadedbytapatalk1442075300.528584.jpg

Hi.. This is how my home network looked like before I broke it. I just wanted to use my media server outside my network through Internet. But couldn't. May be I just needed a port forwarding or something. Please let me know what do you think of this setup.

You got a network of a small business at home

Well, did they tell you that double NAT was a complete show stopper? or just needed some extra configuration? Forwarding the ports to the next router and to the server should get you access (normally).

Now, can you check your modem if it can work in bridge mode? That way your DDWRT router would get an Internet (Public) IP on its WAN port. LAN side doesn't need any change.

(Since I couldn't exactly understand from your description) Then connect the ethernet cable that comes from the 16-port switch to a LAN port of TPLink router. (Make sure you disable its DHCP and change LAN IP to 192.168.2.2 (for simplicity sake)).

Now all your devices will be in a single subnet of 192.168.2.0/255.255.255.0 while still be able to communicate with each other.

Adjust the TPlink as described even if modem can not be used in bridge mode.

Do you know which ports and protocol does Plex server use? Is it simple network file sharing?

Help configuring my home network.

Hi GokAy.. Thanks for replying in detail. Yes you are absolutely right all I needed was to forward a port to the next router and it could have solved the problem , I wish I had known this before I started messing around.
I have also tried connecting my modem in bridge mode and so far I ve been unable to make it work like this. But I have found posts in other forums which tells some others have successfully accomplished this with the same ISP. I am looking at this option currently.
I will also try what you have suggested but if I disable DHCP on the last router how will I be able to get wireless and wired connectivity automatically. ??

If you connect the 16 port switch to a LAN port of TPLink (DHCP must be turned off, or it will cause problems) then all clients will get IP from DDWRT, and TPlink will work as a switch and wireless access point. Also make sure you change its LAN IP to a static in same subnet so you can manage it if needed without having to change IP settings.

I realize now that I assumed ddwrt is compatible with a bridged modem. See if this helps you - DSL with DD-WRT - DD-WRT Wiki

Help configuring my home network.

All fixed.. It was a simple port-forwarding issue as you suggested and took me four days to fix. Thanks for pointing in the right direction.
All I had to do was setting the local router's IP in the DMZ of modem and then port forwarding in the router to the server.
Bridge mode didn't work for me.
