While you can create a SOHO 6 to SOHO 6 VPN, you can also create a 
VPN with a WatchGuard Firebox II/III, Firebox Vclass, or other IPSec-
compliant appliances.

• The following information from your Internet service 

provider for both appliances:

 - Static IP address

 - Primary DNS (Domain Name Service) IP address 

(optional)

 - If available, a secondary DNS address

 - Domain name (optional)

• Network addresses and subnet mask for networks. By 

default, the Trusted network address of the SOHO 6 is 
192.168.111.0 and the subnet mask is 255.255.255.0.

The internal networks on either end of the VPN tunnel must use different  
network addresses.

To create an IPSec tunnel between appliances you must add 
information to the configuration files of each that is specific to the 
site, such as external and trusted IP addresses. It is imperative to 
keep these addresses accurate. WatchGuard recommends making 
a table of IP addresses such as the one outlined below.
