IKE (IPSec) Pre-Shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to
128 characters. Both sides should use the same key. IKE is used to establish a shared security policy
and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can
be passed, each router must be able to verify the identity of its peer. This can be done by manually
entering the pre-shared key into both sides (router or hosts).
