N56U (3.4.3.6-064) internet passthrough to other conected router - How?

[GoogleCodeExporter]

Hi 

I am out of my comfort zone and need some help.

I own an Asus RT-N56U running firmware custom firmware 3.4.3.6-064

I also own a Netgear WRN2200 running firmware: DD-WRT v24-sp2 (03/25/13) std

The Asus N56U is set up using PPPoE for internet access using a wireless link 
to a private server and is working well.

I would like to change my geolocation using VPNUL 
http://vpnuk.info/setup-dd-wrt-router-openvpn.html for media streaming 
purposes, Netflix etc. 

I have hooked the two together using the WAN port on the netgear and one of the 
LAN ports on the Asus (the Wan port is in use for the incoming internet) First 
I have to get the internet to pass through the Asus N56U to The Netgear WRN2200 
....... I have tried everything but I am out of my depth and need somebody who 
knows what he is doing. HELP!

Try to switch off dhcp server on dd-wrt. Set dd-wrt ip address from asus local 
subnet. Connect asus lan port to dd-wrt lan port. It should work as a switch 
then. You won't need any nat settings on dd-wrt as you are behind nat with 
asus. You will need to forward traffic 
http://my.router/Advanced_VirtualServer_Content.asp from port 1194 tcp (or 
other - depends on your openvpn serv settings on dd-wrt) to ip address of 
dd-wrt.
Something like that should work... :)

Thank you for your help ..... I really do appreciate your time. Unfortunately I 
have been trying to make this work for about a week and the Netgear WRN2200 was 
newly purchased. It was becoming painfully apparent that I may have 
“rushed” into this project not understanding the complexity and possibly 
bought an inappropriate wireless router. I took it back for a credit note this 
morning.

I now need to do some research about what to buy BEFORE purchase. What is the 
best hardware to use?

At the moment I own:

Asus RT-N56U
Netgear WGU624
Netgear WN2000RPT
Thomson 77D2EB
TP-Link TL-WR340G

In spite of all this kit, I think I may have to go shopping! So what am I 
trying to achieve?

1.  A powerful (fast/strong internet signal) around the hose. This requires a 
Multiband Wireless, Modem, Router that connects to my ISP via PPPoE. Connected 
to this device will be two WD USB hard drives that required Wan & Lan access. 
The Asus RT-N56U currently fills this role.

2.  Anther device connected wirelessly to the above Multiband Wireless, Modem, 
Router will provide a second SSID Wi-Fi device that will run DD-WRT and OpenVPN 
(VPNUK) 

Item 1 will have its own SSID and will provide “Normal” internet (No 
tunnelling/geochanging).

Item 2 will have a separate SSID and will mainly be used for geochanged media 
streaming via the internet or Lan. It may have another WD hard drive connected 
via a usb connector at some time in the future.

Regarding the wireless link between the two devices, at the moment I don’t 
fully appreciate the difference between “Repeater Bridge” & “Client 
Bridged” mode, but I believe it will be one of the two. It is important that 
I can access all devices on the Lan no matter which Wi-Fi device I logged into.

I like the look of the Asus RT-N66U and could use as item 1. But if I do that, 
since the RT-N56U can’t run DD-WRT it may have to be retired! So perhaps I 
could use the RT-N56U as item 1 and an RT-N66U as item 2 (future proofed device 
– overkill!)

What hardware would you buy in my situation?

First thing: Keep in mind that there is a difference between a router being 
setup to use OpenVPN as a server and as a client.
As a server- You could be at a coffee shop and connect your laptop/phone, 
securely, to your home network. This would keep people at the coffee shop from 
seeing what you are doing and communications would pop out of your home ISP 
connection.
As a client- All outbound network traffic at your home is encapsulated and sent 
out to a VPN provider. If you normally run a VPN tunnel on a home computer out 
of your house, to pop out in another country lets say, every device is running 
its own VPN client software. If you have the router run its own client though, 
you have the neat advantage of not needing to install, configure, etc a client 
on each computer. All traffic on said router would funnel through to the VPN 
endpoint.

Both DD-WRT firmware and the firmware offered here and do both modes. Overview 
from DD-WRT though: 
http://www.dd-wrt.com/wiki/index.php/OpenVPN#OpenVPN_in_DD-WRT

That said, you are wanting two completely different networks, one behind the 
other, for different purposes. This isn't an issue and is done all the time at 
companies for example. You wanting to have a wireless link between the two may 
be an issue depending on expectations. client or as a server. Regarding 
OpenVPN- I believe that if it is a client or server on the second router, you 
simply need to port-forward the appropriate ports from the first to the second 
router. More than likely, you will need the firewall disabled on the second 
router. (Not really an issue, because it is behind your primary. Static routes 
may need to be created to have everything talk properly. You have to be careful 
when you have two networks directly talking to one another though.

Keep in mind that for the best performance, the routers are linked together via 
CAT5 cabling. This is simply due to gigabit being faster than 802.11 N on both 
2.4 and 5 GHz. If you have your heart set on wireless, you will need a router 
in wireless client mode. The RT-N56U can not do this with the stock nor custom 
firmware at this point. You would need to load DD-WRT onto the RT-N66U and go 
from there.

That addresses the two separate networks linked together.

Here is a wonderful table showing difference in the repeating modes:
