PPTP server default gateway

I am trying to setup a vpn but when i setup the account and ip in the ppp secret the ip gateway is 0.0.0.0 on the pptp clients and on me.Is there any way that i can send also a specific gateway to pptp clients and to pptp server so i dont have to route all 0.0.0.0 to my internet line?I have 2.8.28 version,if i upgreade to 2.9.x solve this problem?

Do you build the local ip pool to make the dhcp ??

If not just go and see

ip pool

and setup it

No i am not using dhcp but static addresses to give addresses to pptp clients.If i put this addresses in ip pool and then give them to the pptp client will solv my problem or i must use dhcp?I would prefer not to use dhcp but if there is no way i will have to.
