In a non-IPSec VPN environment, the packet would now be on its way to CPE B.
This is the most practical configuration for an IPSec VPN network.
Cisco also announced recently extensions to the VPN capabilities in select models of its high-performance PIX 525 and 535 Firewalls.
The growing demand for VPN connectivity reveals significant business benefits.
However, if you're using POTS (plain old telephone service or a regular phone line) at one end of the VPN, response time may be unsatisfactory as a VPN can be slow.
Using both remote-control software such as pcAnywhere, and a VPN, you now have many advantages--functionality and performance using pcAnywhere, and security and cost savings using the VPN.
Adding hardware to a general-purpose computer can boost VPN performance somewhat, but bus speed and other architectural limits make this an intermediate solution.
High performance VPN systems and appliances boast a design that incorporates board layout, processor speed, driver optimization, and custom security ASICs for public key operations as well as encryption.
SafeNet's SoftRemote product family is the de-facto standard for VPN
client software with millions of users worldwide.
Automatic Data Delivery: Advanced networking features enable any IP application to communicate directly to the mobile device through the VPN
tunnel, such as Microsoft's Direct Push Technology to send e-mail, calendar, contact, and task updates to Windows Mobile powered devices as items arrive or change on the server.
