Hello , can plz someone can direct me how to configure a vpn on an interface so that when someone will be connected to the interface of the router i will work with the vpn and will connected directly to the vpn network ?

INTERNET>>>ETH PORT 2 >>>>VPN>>>> CLIENT (connected to the vpn )

i have the Vpn login/psswd infos and the ip address to connect to the vpn network , i want to set it on a eth port so connection from the client side will appear as coming directly from the vpn and not the DSL directly

Doesn't VPN creates it own interface on the router?
Make this interface your default gateway, and add nat masquerade on that interface. All traffic on your lan will be directed the VPN tunnel and not the DSL.

Only stateful vpn creates interfaces.

finally this is an exple found
