For example, there is a PIX firewall with 18.104.22.168 as outside interface's IP and 10.6.10.230 as inside interface's IP. And this PIX is holding an PPTP configuration which enabled on outside interface. Because the PPTP clients must be assigned an IP local pool, can the IP range of this local pool be on the same subnet of the inside interface? For example, the IP pool is 10.6.10.231-10.6.10.235. Is this possible? These PPTP client will only access 10.6.10.0/24 subnet. No next hop subnet exists in PIX "inside" subnet.
