Network layout. Internet thru VPN

Specs: Windows XP, 2048
Hello guys. I have a network to build but can't figure out the settings.
I have 2 locations A and B witch are connected thru VPN MPLS. At location A I have the domain server and about 30 users, all in subnet. The vpn router has in location A and in location B. In location B I also have the email server and a few other computers in subnet. Also there is connected in B location a Linksys RV082 router witch is connected to the fiber link for internet. Linksys has for LAN IP in location B. Now, I need all the computers from A and B to access the internet from the linksys router. The ones in A location should access internet from B location by VPN line. I also need that all computers in A and B to reach eachother.
Right now if a computer from B has linksys router as gateway it can surf the web, but it cannot be seen by any computer from A location. If it has as a gateway the vpn router ( then it can see the computers in A location, but cannot surf the web anymore. I couldn't connect to the internet any computer from A location.
The VPN routers are Cisco 1803 and they belong to my internet provider, I cannot change anything there, only the Linksys router. If needed I could contact the ISP to make changes in Cisco routers.
I attached an image with the layout. Can you give me any advice please?
Thank you very much.

I don't understand the IP addressing scheme you've configured on your routers in that figure.
Howcome you're using private addresses on the interfaces of the routers that connect to the VPN? Aren't they supposed to be public IP addresses assigned by your ISP?

You might simply change the subnet mask for each computer and router in both locations from to

Please send a reply, if you solved the problem !!!

bob808 diagram is missing the ip addressing inbetween the vpn routers. He is listing the lan side ip addresses of the vpn routers.

I don't think the linksys is a sophisticated enough of a router.

You need a router with multiple ethernet interfaces like a Cisco. One going the 89.x.x.x. and one going to In the router you would need to specify persistant routes. One going to the 192.168.2.x network and all the rest going to the 89.x.x.x internet network.

Your lan would be in an entirely different subnet that any you were working with.

With your present setup there is no way to tell the pc how to get to the other side of the vpn AND the internet since both have the same gateway. This leaves it up to the router but the router only routes traffic to 89.x.x.x from side b.
