Platform Notes
FortiGate is a Firewall/VPN appliance, manufactured by Fortinet, that runs on proprietary hardware. The operating system is FortiOS.
It supports both site-to-site and remote access VPN.
Version History
Backoff Patterns
Vendor IDs
Authentication Methods
Fortigate supports Pre-Shared Key (PSK) and RSA Signature authentication methods.
ISAKMP SA Lifetime
Lifetime in Seconds
Fortigate supports no lifetime, or any lifetime represented as a 4-byte variable length attribute from 1 to 0xffffffff inclusive. It also accepts a 2-byte variable length attribute for the lifetime.
It always responds with the same lifetime value that was sent, and always replies with a variable-length attribute, even when the lifetime could be represented in a fixed-length attribute.

It does not accept a 1-byte variable length attribute or anything above 4-bytes.

It also accepts a lifetime value as a basic attribute, and in this case will use a basic attribute in its reply.
