9
• Tunnel Mode
Tampering with this option can alter the usability of applications, i.e. from weird effects to crashes with data loss.
The available modes are UDP, TCP and Hybrid. The mode Hybrid combines the best of both connection
types: reliability of TCP and response of UDP.
• Tunnel Rekey Time
Time in minutes after which client and server exchange new keys.
• Tunnel Encryption
Several different encryption schemes, such as AES, CAST, Blowfish, etc.
• Tap device
Defines the tap device used for the VPN tunnel. Linux now uses the universal TUN/TAP
driver. Therefore use /dev/net/tun as tap device.
• Keepalive
This parameter defines the timeout for re-connecting the tunnel. When having a GPRS connection
this value should be increased to avoid permanently reconnects due to dropouts.
• Configure DNS
With Yes selected the system’s DNS configuration is replaced with the VPN provided one,
and the VPN domain configured on the VPN server is added to the search path in
/etc/resolv.conf. With No selected, the VPN provided DNS configuration is ignored.
Merge effects that the VPN provided DNS configuration is merged to the system’s DNS configuration.
On Linux and OpenBSD the configuration is saved to the plain text ASCII-file
/etc/barracudavpn/barracudavpn2.conf.
On Mac OS X The configuration is saved to the plain text
ASCII-file /System/Library/barracudavpn/barracudavpn2.conf.
