Site to Site VPN with Linksys RV042 using ADSL Dynamic IP

There is immediate requirement to setup Site-to-Site VPN from our head office to branch using ADSL dynamic IP and for that we have planned to procure below hardware, i would like to know that below hardware is correct and how we can setup VPN tunnel between two sites.

2 Linksys WAG200 ADSL Router for each site
2 Linksys RV042 VPN Router
ADSL line at each site

This equipment will work well for site to site VPN. I have set up a couple of dozen RV042's and had great success. However, though based on the instructions in the link below it will support 2 dynamic connections I think you will have difficulty connecting and maintaining the connection sometimes if one is not a static IP, preferably the primary office.

You will also need to subscribe to a free Dynamic Domain Name Service such as www.dyndns.com or www.no-ip.com to deal with the dynamic addressing.

Thankx for the post

What configuration needs to be done at Linksys ADSL router like WAG200

Since ISP ADSL will be connected on that router and dynamic IP will be received on that router. Also VPN passthru configuration and Network settings between ADSL router and RV042 VPN router. I am not clear about this configuration.

vpn tunnel show connected at both routers

but i am not able to ping any of the networks and how my clients on the branch network can access servers on the corporate network, do i have to do any additional confguration

Rob Williams

If the VPN is shows connected and you cannot ping or access any shares it is usually due to the subnets being the same at both sites. Both sites MUST use a different local subnet. For example they cannot both use 192.168.0.x

If that is not the problem, check any software firewalls. Most, such as the Windows firewall, by default only allow connections from the local subnet. They need to be reconfigured, or the firewall scope options changed. There is an outline for reconfiguring the Windows firewall scope options for the remote desktop service at:
