I realised I may have been under a misapprehension here....

Messing about with L2TP & Ipsec again


So if I follow the documentation and have this as basic:

virtual-private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12


The ipsec server sits on a 192.168.100.0 network and issues DHCP itself
in the range

192.168.100.0 - 192.168.100.100


The L2TPD dial in server gives out a few IP addresses in the range:

192.168.100.176/28


It has this in the ipsec connection setting:

rightsubnet=vhost:%priv


I *think* that the virtual-private line should be like this:

virtual-private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12,
%v4:!192.168.100.176/28


Can someone confirm that this is correct, or am I missing something?
