VPN and FIX IP

Hi!

I have a problem,I hope somebody have the key…
I have a mickrotik router and i set up the openvpn connection on the router. I would like to use the fix ip of the router when i connect with a client computer. I need to see the router’s fix ip on the client when i browse a website.
Please,somebody…

Direct all traffic to your router. Use default gateway for your vpn connection.

Thanks.
