Home network, multiple "routers"

[gobel]

I'm trying to tweak my home network, but something just isn't working properly.

Here's what I'm trying to do:

VPN router connected to ISP modem, and a wireless router connected through VPN router to provide wireless connectivity to various laptops, iPhones, PCs with wireless NICs, etc.

The VPN router is hosting a tunnel to a business network which runs AD and DNS which I need to access from wired and wireless nodes on my network.

Current setup:

Wireless router is connected from a "client" port (e.g. not the "Internet" port") to a "client" port on the VPN. VPN internet port is connected to modem.

DHCP relay is enabled inside the VPN router. Primary DNS in VPN is set to local DNS server, and an opendns box as secondary.

DHCP is enabled inside the wireless router. Same DNS settings are in place in the wireless router as in the VPN router (I believe this could be a key problem, but not sure what it should be set to...).

All wired machines are connected through VPN router, currently with static ip addresses assigned. They seem to be functioning properly for LAN and WAN connections.

Issue(s):

Wireless nodes (set to dhcp) connecting through wireless router seem to have no network access, although I can access both router interfaces through browser.

Pinging google from the wireless router results in 100% loss both by ip and name.



I'm hardly a networking guru, so there could be a glaring error here that I just don't see. I've been trying various configurations and tweaks with suggestions and input from various google searches and the router help pages with no success.

Does anybody have any suggestions or a simple explanation of how this setup should be configured? Perhaps I'm totally gone down the wrong track...

Thank you.
