DigiTunnel Frequently Asked Questions
What is DigiTunnel? - A Virtual Private Network (VPN) client for Mac OS X, compatible with Windows 2000, Watchguard, Nortel, OS X Server 1.2 and other VPN servers. DigiTunnel supports PPTP (Point-to-Point Tunneling Protocol), an Internet standard for VPN.
What Internet connections can it work over? Any common method may be used: dial-up, cable modem, DSL, T-1, etc. PPTP runs on top of your existing connection.
What's the difference between VPN support included in Mac OS X and DigiTunnel? On OS X 10.5 (Leopard), DigiTunnel provides compatibility with a variety of VPN Servers, the most flexible split-routing to connect directly to Internet sites while on the VPN, and allows customization of PPP options. On OS X 10.4 (Tiger) and earlier versions, DigiTunnel also adds advanced VPN features without needing to upgrade the OS. DigiTunnel Setup Assistant and the system-wide control/status menu make setup and use a snap. Prompt email and phone support is provided.
If you are installing 10.2, please run Uninstall DigiTunnel in /Library/Application Support/DigiTunnel first. If you've already installed 10.2, go ahead and run Uninstall DigiTunnel, then install the new version.
Does it work with DAVE? Yes, DAVE supports DigiTunnel! DAVE users, upgrade to DAVE 4.0.2 to use DigiTunnel 1.1. Earlier versions of DAVE were not compatible..
OS X's Finder can open Windows (SMB) shared folders over DigiTunnel VPN.
Does it work over a NAT router, including Airport's NAT? That depends on whether the router supports PPTP. Airport "Snow" (dual ethernet) works with Airport software 2.0.4 or alter. Airport "Graphite" only supports PPTP if its NAT is turned off. See our report and workarounds.
Does it work with my non-Microsoft PPTP server? Perhaps. Some other PPTP servers, including Watchguard Firebox, are compatible. See our Compatibility List
What about IPSec? We have no plans to support IPSec, an alternative protocol to PPTP. PPTP is a mature, well-defined protocol supported by many VPN servers and NAT routers.
What kind of authentication and encryption does it support? MS-CHAP, MS-CHAPv2 and MPPE (40-, 56-, or 128-bit key), respectively.
Do Classic applications work over the VPN? Older versions of DigiTunnel through 1.4 support Classic. To obtain an older version, contact Gracion Software. (Note that Classic applications cannot take advantage of split-routing--that is, they can't see machines on the local network).
What version of Mac OS is required? DigiTunnel 1.1 requires Mac OS X 10.2. DigiTunnel 1.0 is still available for Mac OS X 10.1 through 10.1.5.
Can all my Internet traffic go through the VPN, or can some traffic (like browsing Yahoo) go direct, unencrypted? Yes, via "split-routing." When all traffic goes through the VPN, a proxy service at the office is used to handle your connections to the Internet beyond. Classic applications always go through the VPN. Only native applications can use the direct mode when DigiTunnel is connected.
I need unencrypted PPTP to connect to my DSL provider (probably in Europe). In some cases you can use DigiTunnel for that. There is also an unsupported freeware product, PPTP-GUI, from one of the developers of DigiTunnel, Andreas Monitzer. Get PPTP-GUI here.
