¾ Common VPN Scenarios
Generally there are two common scenarios in which you will want to set
up your SnapGear appliance(s):
• LAN-to-LAN: Linking two branch offices across the Internet. For this
case we recommend using IPSec. The SnapGear VPN can operate
with both static and dynamic public (Internet) IP addresses.
For the example below we assume SnapGear appliances are installed at
either end, and both have a static public IP address, or one is static and
one is dynamic. The example tunnel will be using pre-shared keys for
authentication, aggressive mode for keying, and be established going
out through the default gateway interface. Proceed to SnapGear to
SnapGear VPN (IPSec).
Please refer to the IPSec section of the User Manual if you are
trying to set up something more complex, and for a detailed
description of all available options.
• Roaming: Connecting to your SnapGear appliance, installed at your
home or office, from a single PC at a remote location. For this case we
recommend using PPTP because the client is standard in Windows and
other operating systems, and it is quite simple to set up. Proceed to
Remote Workstation to SnapGear VPN (PPTP).
SnapGear to SnapGear VPN (IPSec)
Perform these steps for either end of the connection. Unless instructed
otherwise, leave all options at their default settings.
STEP 1 Enable IPSec
Select IPSec from the VPN menu.
Underneath IPSec General Settings select This SnapGear has a
static IP address IPSec endpoint, or This SnapGear has a dynamic
IP address IPSec endpoint as appropriate. This is referring to the
public (Internet) IP address of this SnapGear appliance. Check with
your ISP if unsure.
Check Enable IPSec, and click Apply.
