    Okay so several months ago i signed up for a VPN service to stop throttling and other issues. At first I had a simple setup where everything routed through the VPN running on an RT-N16 running tomato. I found however that i did not want everything on the VPN.

    So I found a script to route only certain IP addresses through the VPN. Although this worked it became a problem when I started using some other features like QOS and my work software VPN. It got really complex. CPU usage was also becoming a problem. I work from home and use the internet alot and found the CPU (on the router) was always running very high.

    Next i decided to just run the VPN software on the PC's themselves and start just when I wanted them to. But I found this bad as well. I have a smart TV for example that I liked on the VPN because i was able to stream content normaly only available when I am in the US

    There are hours and hours of things that I have done and I wont bore you with all the details I just wanted to give you a sense of how I got to where I am today.

    I have since purchase the RT-N66U because I really like ASUS. Now what I would like to do is setup my old RT-N16 as the VPN router. Then selectively route traffic that I specify ether by source or destination IP to this router.

    Although i know this is possible from reading some other posts I need some help with the config.

    Currently main router is 192.168.1.x and my Second router for VPN is 192.168.2.x.. I was thinking of plugging the WAN port into one of the LAN ports on the primary router and configuring the WAN as PPTP VPN and connecting to my VPN service. I dont know if this is the right way to do this? Then I was thinking I need to go to my primary router to setup the routes that I need.

    I hope all that rambling made some sort of sense.

    Here is where I am now... I am so close..

    Main router running LAN IP of 192.168.1.x
    WAN connected to internet (cable modem)

    Second router running LAN IP of 192.168.3.x
    WAN connected to 192.168.1.x for internet .... using PPTP to tunnel traffic through VPN.

    All works perfectly with one exception.

    Devices on 192.168.3.x can see 192.168.1.x devices but not the other way around.

    I thought by disabling the firewall on the second router it would take car of this but it does not.

    Any ideas? Suggestions?

    I suggest finding the thread from a few weeks ago that discussed how to do what you're trying to do, and using only one router.

    Got it... needed static route on each others LAN to route local traffic from each other...
