VPN problem

[networkmyth]

HI i am using 2 routers one is Linksys AG300 which is an ADSL modem router and the other one connected to it is WRV200. WRV200 doesnt have an RJ11 port so i cant connect to the internet directly so have to use AG300 instead, But the main problem is that i need to create a VPN connection with WRV200 and i cannot do it because there are 2 NAT's being used, how can i disable one NAT (the way i know is to ask for the ISP to put our ADSL router on the bridge mode) is there any other way to put my AG300 on the bridge mode or altogether any other way to get around this problem .......its a CLIENT TO ROUTER

I am posting the WRV200 Log as well if it helps ..

Thanks very much in advance.

(the way i know is to ask for the ISP to put our ADSL router on the bridge mode)

Just a few minutes on the phone with their support. I always bridge the ISP supplied gateway device and use the router of my choice for my setups.
