||VPNs and IPSec Demystified|
I have four sites com adsl. I would like to make a VPN between them. The first has a unique ip, like as 184.108.40.206 and others has no unique ip. They have dinamic ip assigned by carrier ADSL company. All have adsl router and I think to put freebsd vpn server between adsl router and local network. Is this design possible?
