TunnelVision
TunnelVision, you have a similar situation: the server side (accepting a connection) needs a
static IP address, while the client side can have either a static or a dynamic IP address.
Only one Black Box® IT Pro™ (usually the computer with the fastest Internet connection at
your head office) needs to act as the server and have a static IP address. All the others can
simply act as clients.
Please Note: A static IP address is guaranteed never to change, so people on the Internet can always
find you. To obtain a static IP address, talk to your ISP. DDNS can be used in place of a static IP
address. Refer to
Dynamic DNS in Chapter 22: Domain Name Services for more information.
Configuring a TunnelVision Master Server
Ensure that the Black Box® IT Pro™ you are configuring as the master server has a static IP
address.
1.
Select VPN from the Network Setup menu on the left side of any WebConfig screen. The
VPN Setup screen displays:
2.
Leave the default Enable PPTP Server setting, Yes .
3.
Select Yes in the Enable Tunnel Vision section of the screen.
4.
In the Tunnel Vision: Use Fully Meshed Mode? box, select Yes to run Tunnel Vision in a
Fully Meshed mode, and No to run it in a Non-Meshed mode.
Please Note: If you enable TunnelVision to work in "fully meshed" mode, then your server can learn
about other servers on the VPN by exchanging information through the Master Server. Then each
server will make connections directly to each of the other VPN-connected servers directly, as needed,
without needing to go through the master.
If you disable "fully meshed" mode, then your server will only communicate directly with the master
server and the master's local network. Your server will not be able to see any of the other VPN-con-
nected servers or networks.
