We know that the network functions have been greatly improved in Microsoft's Vista system, especially when the settings are very different from those in previous versions, this makes it difficult for many new users who have just installed the Vista system. Next, I will teach you how to create and manage a VPN personal virtual network in the Vista system.

The IPSec VPN realizes the network expansion, the firewall realizes the control and the filtering to the network traffic, therefore has the influence to the IPSec VPN communication.
The default ASA maintains a state session only for UDP/TCP traffic, and therefore discards the ESP traffic that is returned. There are tw
What if the network becomes restricted after the WIN8 system is connected to the VPN?
Workaround:

upgrade from one wireless technology to another without replacing the hardware.
A hybrid approach may include using client software with existing Wireless AP and planning to transition to a new device-based product. Another method is to specify a server in DMZ (or in its own network segment) to handle wireless connection, VPN gateway requirements, and firewall information, and enable or disable the wireles

The N2N peer-to-peer VPN Network n2n is a two-layer virtual private network that allows users to develop typical P2P applications in the network rather than at the application layer. This means that the user can obtain the local address transparently, as long as the new IP address is in a sub-

Solution 2: wired
The cable solution can only deploy single-mode optical fiber cables at a distance of 12 kilometers, which is more time-consuming and costly. You can say you don't have to think about it.
Solution 3: Internet + VPN
The Internet can be said to be a public wide area network, and many telecom operators have established a four-way and eight-way long-distance

The RD and VRF tables have a one-to-one relationship. Generally, for sub-interfaces of the same VPN on different PE routers, allocate the same rd to the corresponding VRF table. In other words, is to assign a unique RD for each VPN. However, for overlapping VPNs, that is, when a site belongs to multiple VPNs, because a sub-interface on the PE router belongs to multiple VPNs, the VRF table corresponding to
