L2TP custom IP allocation within subnet
-
Hello, I've set up a new pfsense installation and I can't work out how to do what I want with the L2TP configuration.
My LAN network is 192.168.0.0/16. I want L2TP clients to be assigned that network, but I specifically want them to be assigned addresses starting from 192.168.50.1. The pfsense GUI doesn't seem to let me do this - if I try typing in 192.168.50.1/16 it resets the fields to 192.168.0.0/16 when I save. The first client that connects receives the address 192.168.0.0, which is no good.
The reason I want this is that VPN clients are able to access every host in 192.168/16 without having to make the VPN gateway the default router, i.e., clients can continue to use their own internet connection. This is very useful.
Ideally I would have the VPN clients on their own subnet and "push" an extra route for 192.168/16 but I don't think this is possible with L2TP, only with OpenVPN.
Is there any way I can make pfsense do what I need? Many thanks!
Edit: To make myself clear, I am looking for a setting like this one in Forefront TMG:
