Linux - VPN Diagram

I have a linux router....i have to do a vpn.... so i have to set any outgoing VPN access will have to go trough my linux router...so in my router i must set the firewall to open the connection....then if verified, the connection will transfer to my windows based vpn server pc.

but i got a D-link VPN router where i want to use it....so is that ok if from the linux router i connect to the D-Link VPN router, and from that it will go to my windows based vpn server pc..

any idea?

It should work. On the linux router, are you going to use frees/wan? It will be a tricky config, but it should work, assuming you are looking for this:
network->linux router-> vpn tunnel -> d-link router -> network

the linux router is just fowarding the vpn access from external...so vpn tunnel is a pc or software?

nalanbar

a vpn tunnel is the stream of encrypted packets going between the two routers. If you think of the internet as a cloud, the vpn tunnel is like an opaque tube that runs through it. No one on the outside can read it, but all of your data is sent accross the open internet, but is encrypted.
I guess I should have asked this question first:
Are you using the VPN to connect two different sites, or is it to allow people with laptops to connect from the road?

i use the vpn for other site of my project to upload data to my server...the other site only has dial up...

So it is not a constant connection. You will be connecting for a little while, transfering data, and then disconnecting?

it seems to be like this:
