What you're describing is not really routing if they're all on the same subnet. Can I ask what you're trying to accomplish? There's (likely) a different/better way to achieve what you're trying to do. – gravyface Nov 28 '10 at 3:09
If the IPs have the same prefix does not always mean they are in the same VLAN. You can have PPP interfaces with /32 prefixes. – Mircea Vutcovici Nov 28 '10 at 4:42

It should be an option in the PPTP server to allow the clients to inter-communicate. I suggest to use a better/secure VPN solution like OpenVPN, etc.

You can't but your router could. :-) Just be sure to enable it doing so: sysctl -w net.ipv4.ip_forward=1
