Investigating the Cyber Breach: About Affiliates Cisco Systems, Inc. These scripts unload the Cisco AnyConnect tun kext before a Tunnelblick connection is started, and reload the Cisco tun kext after a Tunnelblick connection is stopped. The Cisco kext interferes with Tunnelblick's operation of tun connections. These scripts mount a volume after a configuration is connected and unmount it when the configuration is disconnected.

Scripts must be edited before use in any plain-text editor to specify details of the volume to be connected. For a note about connecting to a CIFS account, see this discussion. These scripts provide a mechanism for the user to be alerted when the VPN has been up for more than 20 minutes or when bandwidth has exceeded MB. See this discussion for details. Includes compiled binaries; use at your own risk. Scripts to Launch and Kill a Program: It can be used with a torrent program, for example, so that the program is only active when the VPN is connected.

Note that there may be a short time after the VPN has been disconnected before the program is killed.

SoftEther VPN has strong resistance against firewalls than ever. Built-in NAT-traversal penetrates your network admin's troublesome firewall for overprotection. You can setup your own VPN server behind the firewall or NAT in your company, and you can reach to that VPN server in the corporate private network from your home or mobile place, without any modification of firewall settings.

It virtualizes Ethernet by software-enumeration. A VPN session is the virtualized network cable. Therefore, you can safely establish a VPN session beyond the Internet. The behavior is same to traditional Ethernet switches. You can define a local bridge between the Virtual Hub and the existing physical Ethernet segment by using the Local Bridge function. You can realize a remote-access VPN from home or mobile to the company network by using the Local Bridge function.

You can define a cascading connection between two or more remote Virtual Hubs. With cascading, you can integrate two or more remote Ethernet segments to a single Ethernet segment. For example, after you establish cascading connections between the site A, B and C, then any computers in the site A will be able to communicate with the computers in the site B and the site C.

This is a site-to-site VPN. You need no network administrator's special permission before setting up a VPN server on the company network behind firewalls or NATs. Despite long-distance, it is easy to communicate mutually with any kinds of LAN-oriented protocols. Geologically distributed branches are isolated as networks by default. Then all computers of all branches are connected to the single LAN.
