External

 

The overlay of bits that determines which part of the IP

ISP

Subnet

 

address identifies your network. For example, a Class C

 

Mask

 

address licenses 256 addresses and has a netmask of

 

 

 

255.255.255.0.

 

 

 

Site A:

255.255.255.0

 

 

 

Site B: 255.255.255.0

A private network address used by an organization’s local

network for identifying itself within the network. A local

network address cannot be used as an external IP address.

 

 

 

WatchGuard recommends using an address from one of

 

 

 

the reserved ranges:

 

 

 

10.0.0.0/8

 

 

 

172.16.0.0/12—255.240.0.0

 

 

 

192.168.0.0/16—255.255.0.0

 

 

 

Site A:

192.168.111.0/24

 

 

 

Site B: 192.168.222.0/24

You

Secret

 

the transmission as being from the claimed origin. The

 

 

 

secret can be any phrase, but mixing numerical, special,

 

 

 

alphabetical, and uppercase characters improves security.

 

 

 

For example, “Gu4c4mo!3” is better than “guacamole”

Method

 

key used to encrypt and decrypt communication packets.

 

 

 

DES is a 56-bit encryption; 3DES is 168-bit, and much

 

 

 

more secure. It is also slower. Select either 3DES or DES

 

 

 

as long as both sides use the same method.
