static routes

[dannimca1]

Hello,   

I have three routers connected like this:

Internet ------- (WAN) RouterA (LAN) ------(LAN) RouterB (WAN) ---- (VPN) ---- (WAN) RouterC

    RouterA: RV042G; LAN: 192.168.100.100 /24

    static route for RouterA: destination 192.168.102.0/24 default gateway: 192.168.100.101 (all traffic to routerC should be redirected to routerB)

    RouterB: RV180; LAN: 192.168.100.101 /24 WAN: 192.168.101.1/24

    I did not define a static route on this router. There is only one VPN connection defined to routerC

    RouterC: RV180; LAN: 192.168.102.101 /24 WAN: 192.168.101.2/24

    I did not define a static route on this router. There is only one VPN connection defined to routerB

    Local DNS ( 192.168.100.200) is installed behind RouterA.

Computers behind routerA have as gateway it's IP (192.168.100.100) and 192.168.100.200 as DNS ( the one behind routerA).

Computers behind routerC have as gateway it's IP (192.168.102.101) and 192.168.100.200 as DNS ( the one behind routerA).

In this configuration all computers from both networks can access ( ping, file transfer) each other ( by IP or by name). Compuers behind routerA have Internet access ( ping, web page browsing ).

I would like to give Internet acces for users connected to routerC but no matter what I have tried I can not make that to work.

I thought that the above route will solve my problem but computers behind routerC still have no Internet access. If I ping yahoo.com ( by name or IP) from behind routerC I get no response; from routerA everything it is working well.

I suppose that I have to define a new static route but indifferent of what I have tried ( from google, tips from friends) I do not get the desired result.

Do you have any tips for me?

Thank you!
