I have set up openvpn server on "RB 751", and I am using a XP client to connect to the Openvpn.
Everything is working fine, I am able to access the devices on the openvpn network, except that i dont know how do i successfully force the Windows XP client to route all internet traffic through the VPN?

I am using "Tap" (not "Tun") method.

My Windows XP clients network: 192.168.43.0 255.255.255.0 (internet gateway 192.168.43.1)
My Openvpn server Private IP. 192.168.3.250 255.255.255.0
My Openvpn client Private IP (windows xp). 192.168.3.243 255.255.255.0

How do i do the route correctly?

I have tried following in Windows XP

route add 192.168.43.0 mask 255.255.255.0 192.168.3.250
route add 0.0.0.0 mask 0.0.0.0 192.168.3.250

But it never really works, or just works partly (some pages load, and some not)..
Thank you for help
