can a DD-WRT router be used as a passthrough VPN internet connection only?

[BirdDad]

I want to use the OpenVPN function of my Linksys router(which came out before gigabit ethernet became big) but would prefer if my Amped wireless router does the DHCP serving. I have tried using the DHCP forwarding setting in my WRT but still can't get them to get along.
I have wireless disabled with the Linksys and want to keep it that way. I don't want the Linksys to handle DHCP.
Does anyone understand what I am trying to do, please help.
Thank you

Yep, any device on your LAN can be the DHCP server.

On your second router, make sure you enter the gateway to the internet as the address of the first router plus the correct DNS info.

 

[BirdDad]

if I enter anything but a 192.168.3.*(in my Amped router) it won't connect and if I change my ip of my DD-WRT to 192.168.3.* I can no longer login to it even if I have the ip right.

 

[JoeMcJoe]

Set the static IP of the first router as 192.168.1.1, the second router as 192.168.1.2

You need to be all on the same subnet, unless you have routing setup.

Disable DHCP on the first router.

Enable DHCP on the second router, starting at address 192.168.1.100 (or so).
Have the correct DNS info in both routers.

I've tried that BTW on WRT there is no option to disable DHCP you can only choose between server and forwarder. I've got mine set as forwarder.
Every time I change the amped wireless router I lose the ability to login on it even with the correct ip same goes for the linksys and I have to reset them and reload the settings.

On the DD-WRT router, go to the Setup tab, scroll down to Network Address Server Settings (DHCP), and change the DHCP Server setting from "Enable" to "Disable". (It's the two buttons immediately below the drop-down box where you can select DHCP Server or DHCP Forwarder.)

Edit: You are probably losing the ability to log in to the routers when you change their IP address ranges because your computer hasn't obtained a new IP address in the new IP address range yet. After you change the settings on the routers, reboot your computer, or open a command prompt and type these two commands:

IPCONFIG /RELEASE
IPCONFIG /RENEW


And then try to connect to the new IP addresses on the routers.

 

[BirdDad]

Thanks Fardringle.
I can now connect to the internet-trouble is is that it won't go through my vpn service on DD-WRT. I have private internet access.
I am not sure what setting is wrong but whatsmy ip.org shows my static ip every time.

 

[Fardringle]

You mentioned that you hard reset the routers earlier. Did you set up the VPN connection again after you did that?

 

[BirdDad]

yes I did.
Now the two routers are talking to one another and I get internet but no VPN.
I cannot log into either of the routers.
Thank you for helping me.

I think that the VPN works on the Linksys only if it is configured as a Router.

 

[BirdDad]

That sucks that I can't use the VPN unless it is a router. It has only 100Mbps inputs and the wifi stinks.
There has got to be some way to make it work.
Thank you.

If your Internet connection is so Fast that it is limited by the WAN capacity of the Linksys, then get a better Wireless Router that can do DD-WRT (like the Asus N66U).

If the Linksys can do the Internet OK, then use it as the main Router with VPN.

Configure the Amped as a switch with an Access Point and use its LAN Ports and Wireless.

I've been trying to setup the same thing and ran into the same problem, that DD-WRT has to be configured as a router w/ it's own subnet or the VPN Client won't work. Haven't figured out a way around it, unfortunately.

 

[BirdDad]

I know it can be done.
I did it and did not know it.
My daughter knew I was messing around with the internet connection.
I was going to give up so I uploaded the saved binary to my Amped router and had reset the Linksys and my daughter came to me and asked me "What did you do? It was working" I asked her when it was working and she said about a minute ago. By that time my amped router had rebooted itself into the saved firmware.
So it can be done. I just got to figure out what configuration I was using before.

Well, make sure you post it if you do figure it out because I've been unable to get DD-WRT to work like that no matter what I try.

Same here.

It is Not doubting BirdDad, it is "Dying" to be able to do it for my systems.

OpenVPN claims this.

[BirdDad]

There's got to be a way to do this, I had it working then flashed to backup firmware and screwed it up.

how do I find the DNS information?

I assume you read through the wiki for DD-WRT? http://www.dd-wrt.com/wiki/index.php/VPN_(the_easy_way)_v24+

 

[BirdDad]

Thanks Mike
No I had not looked through it, I assumed mega was the firmware I should be using. I didn't know there was a openvpn version.

 

[BirdDad]

do they even compile the OpenVPN version for Linksys e1200?
I bought it because it was 18$ and planned on using my Amped for my DHCP server. The e1200 only has a single core 300MHz cpu.

 

[BirdDad]

I have a 3Mbps connection through DSL

 

[BirdDad]

I turned off NAT on the linksys and just turned DHCP off(not forwarding after I changed the ip to 192.168.3.30
everything that was connected to the amped router could access the internet. Just one problem, all these were ignoring the VPN and when I did a whatsmyip there it was clear as could be.
I am going to try again here in a few hours so any ideas you might have please let me know.
