Main
PSK (Pre-
Shared Key)
Prestige gateways authenticate an IKE VPN session by matching pre-shared
keys. Pre-shared keys are best for small networks with fewer than ten nodes.
Enter your pre-shared key here. Enter up to 31 characters. Any character may
be used, including spaces, but trailing spaces are truncated.
Both ends of the VPN tunnel must use the same pre-shared key. You will
receive a “PYLD_MALFORMED” (payload malformed) packet if the same pre-
shared key is not used on both ends.
