I have a Windows 2003 Server (Domain Controller) with a dual-port NIC. One port is used for the LAN and the other is available. We use a Sonic TZ 170 firewall. We have a router for internet access. One outgoing port goes to our Sonicwall firewall appliance. The other port is just an internet connection without any firewall.
I was wondering which way is better to set up a VPN:
1) Use the one port already used for the LAN
2) Use the second available port. As far as I understand, this port needs to be connected to an internet connection. Do I connect to
a) internet router before our Sonicwall firewall
b) an available port on the Sonicwall box. There are 5 ports, one is used to connect to our LAN switch.
c) the LAN switch
