FIELD DESCRIPTION EXAMPLE
Phase 1
Negotiation

Press [SPACE BAR] to choose from Main or Aggressive and then press
[ENTER]. See earlier for a discussion of these modes. Multiple SAs
connecting through a secure gateway must have the same negotiation mode.
Main
Authentication
Method
Press [SPACE BAR] to choose from PreShare Key or RSA SIG and then
press [ENTER].
PSK ZyWALL 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.
Certificate Press [SPACE BAR] to choose the certificate to use for this VPN tunnel. You
must have certificates already configured in the My Certificates screen
