Mac route internet to vpn

[davywavee]

I'm having problems routing my internet traffic through vpn on my mac.

ifconfig -a shows me: PPP:...inet 10.10.0.50--> 10.10.0.1

and assuming my diskstation is 192.168.1.120 and router is 192.168.1.118

when do a sudo route add -net 192.168.1.120/24 10.10.0.1, internet traffic still does not go through the tunnel. Can some one tell me if my route add statement is correct? Thanks.
