A VPN allow companies to take advantage of the cost benefits and ubiquity of the Internet by providing employees and business partners access to confidential corporate data, resources and protected applications.
Whether it is connecting remote offices, offering remote access to traveling employees, or connecting with business partners, MatrixIT offers a VPN solution that will securely extend the network and reduce the costs associated with leased data lines.
Three options for VPN connectivity that we mainly setup are: IPsec, OpenVPN, and PPTP.
IPsec allows connectivity with any device supporting standard IPsec. This is most commonly used for site to site connectivity to other installations, other open source firewalls (m0n0wall, etc.), and most all commercial firewall solutions (Cisco, Juniper, etc.). It can also be used for mobile client connectivity.
OpenVPN is a flexible, powerful SSL VPN solution supporting a wide range of client operating systems. See theOpenVPN websitefor details on its abilities.
- Not all of the capabilities of OpenVPN are supported yet. Support for virtually all of OpenVPN’s capabilities will be included in the next release.
- Filtering of OpenVPN traffic is not yet possible. Support for this is in 2.0.
PPTP is a popular VPN option because nearly every OS has a built in PPTP client, including every Windows release since Windows 95 OSR2. See this Wikipedia article for more information on the PPTP protocol.
The PPTP Server can use a local user database, or a RADIUS server for authentication. RADIUS accounting is also supported. Firewall rules on the PPTP interface control traffic initiated by PPTP clients.
