Nest provides a secure IP VPN cryptographically protected packet tunnel.
Nest is a secure IP VPN tunnel for FreeBSD. It connects two LANs over an insecure WAN.
Nest works on the IP packet level. Its features include packet authentication and integrity checking (with 96-bit SHA1-derived HMAC), packet encryption (with Blowfish and 160-bit key CBC mode), replay protection, adjustable packet queuing, and compression.
The VPN traffic appears on the WAN as a bidirectional stream of IP packets or as a unidirectional ICMP request/response stream. The latter case allows the establishment of VPN tunnels through certain firewalls.
Here are some key features of "Nest":
· Replay protection
· ICMP stream (new in version 3)
· IP masquerading (new in version 3)
What's New in This Release:
· A #define to make the program silent was added. A
· bootable FreeBSD floppy containing the software is now also available for download.
