Setting up Virtual Private Networks (VPNs)

SHA1

Secure Hash Algorithm (SHA) is the term used to describe a group of standardized cryptographic hash functions.

Working together with the National Security Agency, the National Institute of Standards and Technology (NIST) developed a secure hash function for signing as part of the Digital Signature Algorithms (DSA) for the Digital Signature Standard (DSS). It was released in 1994. The name given to it was the Secure Hash Standard (SHS). It specifies the Secure Hash Algorithm (SHA), with a hash value of 160 bits for messages up to 264 bits in size. The algorithm shares a similar structure with MD4, designed by Ronald L. Rivest. There are two versions of the Secure Hash Algorithm: SHA0 and SHA1. They differ in the number of cycles passed through when generating the hash value.

Pre-Shared Key

Similar to a password. Has to be the same on both VPN routers (FSG and remote VPN router).

Operation

1.Establish connection - Allows you to establish a connection with another VPN router.

2.Listen Only - Allows you to accept a connection from another router.

Alive Ping IP

You can enter the router's IP address used in establishing a connection in this field. This involves sending a ping at set intervals to ensure that connection is not cut when no activity is registered over a long period of time.
