OpenVPN is a robust and highly flexible Tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port.
xl2tpd a Layer 2 Tunneling Protocol (L2TP) daemon. It supports IPsec SA reference tracking, which enables the IPsec stacks to support multiple l2tp clients behind the same NAT router and multiple l2tp clients on the same internal IP address. It is a fork of "l2tpd".
Release focus: Minor feature enhancements
Changes:
Support for passwordfd, a workaround for some Cisco routers, and extended logging.
An easy, yet highly-configurable iptables-based firewall solution designed for everybody from home users to network admins. Functionality for IPv6, Tunneling, IPSec, and advanced routing is planned.
The SST89E516RDx and SST89V516RDx are members
of the FlashFlex51 family of 8-bit microcontroller products
designed and manufactured with SST’s patented and proprietary
SuperFlash CMOS semiconductor process technology.
The split-gate cell design and thick-oxide Tunneling
injector offer significant cost and reliability benefits for SST’s
customers. The devices use the 8051 instruction set and
are pin-for-pin compatible with standard 8051 microcontroller
devices.
