PPTP DNS

Hello everybody,

How can i implement somthing like a conditional dns forwarder?

i have a rv750g, 4.6, having with a permanent pptp connection to a vpn server (isa server).
i want to be able to resolve names in the corporate network: computer.domainsufix ->resolve using corporate dns (the dns has a static ip).

thanks.
