Tunnelblick - Project Hosting on Google Code. HOWTO. Introduction OpenVPN is a full-featured SSL VPN which implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or username/password credentials, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. OpenVPN is not a web application proxy and does not operate through a web browser. OpenVPN 2.0 expands on the capabilities of OpenVPN 1.x by offering a scalable client/server mode, allowing multiple clients to connect to a single OpenVPN server process over a single TCP or UDP port. OpenVPN 2.3 includes a large number of improvements, including full IPv6 support and PolarSSL support.
This document provides step-by-step instructions for configuring an OpenVPN 2.x client/server VPN, including: The impatient may wish to jump straight to the sample configuration files: Intended Audience Additional Documentation.

Meet OpenVPN. If your company has people on the road, such as sales or technical people, a VPN is a good method for letting them access data on the company network. Many different VPN solutions can be bought, but many are free. Here, I discuss only solutions you can set up without buying a commercial VPN product. The main VPN solution used for more complex tasks is IPsec; some people use PPTP. Although PPTP is usable, security flaws have occurred in its past, and it simply does not match up to IPsec. IPsec in tunnel mode would be a much better solution, were it not for the crippled Windows-client implementation: Windows XP/2000 clients can't use IPsec in tunnel mode without using L2TP. There is nothing wrong with L2TP security-wise, but it increases latency--through the need for both PPP and L2TP processes--and increases packet-overhead, slowing down connections.
A disadvantage of plain IPsec is its notorious complexity: many, many things can and do go wrong. The list of cons includes: Server Security. OpenVPN - An Open Source SSL VPN Solution by James Yonan.

NOTE: Some ISPs (Internet Service Providers) may block services that would prevent you from getting into your VPN system. Try the procedure first, and we will determine if it will work for you. To enable the Mitel (e-smith) Linux server to have remote access, simply enable the access in the system control panel.
For other Linux or Windows PPTP servers, follow that configuration documentation. You may also have to open up your router or firewall in front of that box (ie meaning between the server and Internet). To configure your PC, please select which operating system* you will use to connect: Unix Linux MacOS Microsoft Windows3.11 (will not work) Microsoft Windows95 Microsoft Windows98 or Me Microsoft WindowsNT 4.0 Microsoft Windows2000Microsoft WindowsXP * Items in black mean that although access is available, the procedure is still being written. PPTP Securely Tunneling to Linux server.
NOTE: Running personal firewall software like ZoneAlarm or Sygate's Fire may cause issues. Either reconfigure these programs or disable them. Some ISPs (Internet Service Providers) may block services that would prevent you from getting into our system. Configuring Windows XP to establish a VPN tunnel (Point to Point Tunneling Protocol) connection to your office network is a straight forward process. The following procedure for configuring Windows XP assumes that a dial up connection to an ISP has already been configured on the client computer.
(or other type of Internet connection) Follow the steps below to configure a PPTP connection: Go to Start -> Settings ->Network and Dial-up Connections then select the New Connection Wizard icon. After selecting Finish, a logon box will appear. Initially, the settings for your connection to the Internet need to be checked to ensure the PPTP VPN connection to your network behaves as expected. Click on the WINS tab. Cisco VPN ports. L2TP protocol is assigned 115 as its port number. IPSec VPN ports assignments for uses of Encapsulation Security payload (protocol 50) and Authentication Header (protocol 51). Port 88 for Kerberos authentication in TCP/UDP and port 500 for Internet Security Association and Key Management Protocol in TCP/UDP. SSL VPN for secure HTTP application uses port 443. MPLS-in IP uses port 137 For the systems that use VPN hardware normally port 500,4500,10000 & 10001 are used. Hardware ports Hardware ports are an entirely different concept compared to software based network ports.
All processors use assembly instructions to access the ports on the mother board or any add on boards. In the many hardware devices in the VPN market if we hear of number of ports being many these are referring to the number of simultaneous hardware connections that can be made. VPN ports for network setting is a bit complex when you have no knowledge of the protocols, the encryption and authentication techniques they use. Hamachi : Stay Connected.
