their lifetime, transmit and receive statistics. The VPN Status screen is read-only with no configurable
parameters. To configure a VPN tunnel, use the VPN configuration screen in the WAN section of the

Diffie Hellman
Group
Select a Diffie-Hellman Group to use. The Diffie-Hellman
key agreement protocol allows two users to exchange a
secret key over an insecure medium without any prior
secrets. Two algorithms exist, 768-bit and 1024-bit. Select
one of the following options:
• Group 1—768 bit—Somewhat faster than the 1024-bit
algorithm, but secure enough in most situations.
• Group 2—1024 bit—Somewhat slower than the 768-bit
algorithm, but much more secure and a better choice
for extremely sensitive situations.
