Why to choose a Firewall – VPN (Virtual PrivateNetwork) Solution ?
In today’s world, more and more businesses are seeking to gain efficiencies in their resources.Forced to do more work with fewer people, organizations are looking for ways to improve the manageability and scalability of their networks without increasing their costs.
With the growing concerns over networks security, Denial of Service attacks, virus damage, and privacy your networks demands a firewall – vpn solution that provides the assurance of a dedicated network security solution.
Ensuring that your data arrives safe and sound when it passes through a network is something
everyone wants to have. In an ideal world, your data’s integrity and confidentiality would be guaranteed.If you believe this all sounds like nothing more than a fantasy, you are wrong.These types of guarantees can be made when you use a firewall-vpn solution.
Virtual Private Network (VPN) – firewalls solutions are designed for small,medium businesses and big enterprise sites, carrier networks, data centers that demand superior security and performance.
Almost all firewall – vpn (virtual private network) solutions provides integrated NAT (Network Address Translation) , SPI Firewall, advanced content filtering features,bandwidth management, IDS (Intrusion Detection System) protection, Virtual Private Network (VPN) support, UTM (Unified Threat Management) – security features including stateful firewall, Intrusion Prevention System (IPS), Antivirus,Anti-Spyware, Anti-Phishing, Anti-Adware, Anti-Spam, and Web Filtering to protect the network from attacks;also includes a trusted LAN (local area network) port, a WAN (wide area network) port that supports virtually all WAN (wide area network) connection types, and an independent demilitarized zone (DMZ) port to support local servers such as e-mail, Web, and FTP (file transfer protocol).
A firewall – vpn solution provide comprehensive and easy to use protection against current and emerging threats at both the application and network layer.
Some firewall – vpn solution like Juniper Networks IDP not only helps protect networks against attacks, it also provides information on rogue servers and applications that may have been unknowingly added to the networks.Also can provides administrators with visibility into specific applications and assets that are present and/or being used on the networks and how, when, and by whom they are being used.
To design and deploying a firewall-vpn solution it is necessary five phases:
- Identify Needs — Identify the need to protect networks communications and determine how that needs can best be met.
- Design the Solution — Make design decisions in four areas: architectural considerations, authentication methods, cryptography policy and packet filters.
- Implement and Test a Prototype — Test a prototype of the designed solution in a lab or test environment to identify any potential issues.
- Deploy the Solution — Gradually deploy the solution throughout the enterprise. Existing network infrastructure, applications, and users should be moved incrementally over time to the new vpn-firewall solution.
- Manage the Solution — Maintain the firewall – vpn components and resolve operational issues; repeat the planning and implementation process when significant changes need to be incorporated into the solution.
Firewall – vpn solutions can be made highly available in different ways, depending on the vendor’s approach.Some firewall-vpn models are built upon software other upon a hardware platform.
Firewall-vpn solutions vendors
The leader on the firewall – vpn solutions market is Cisco, Check Point is second and Juniper third.
Jeff Wilson, principal analyst at Infonetics Research said that “SSL VPNs are starting to come in to their own now, and make a real impact on the market,”

I want to subscribe to the world-secure channel virtual private network software.Will virtual private network software affect my internet speed ?
In general , no but choosing a VPN service depends:
1) if the company you wish to subscribe uses PPTP for their VPN or SSL.
PPTP is less secure than SSL and drops out a lot.
2) Second if the company change their server ip addresses all the time which makes them hard to block.
3) The bandwidth (unlimited or limited)
I want connect to a computer with Remote Desktop via virtual private network connection.
When I am trying to connect to the IP I get a message advising that I cannot connect to the remote computer.
What is the problem ? How can be resolved ?
I think your virtual private network firewall is blocking RDC traffic. You would need to add an exception on the firewall to allow the RDC port through the firewall.
What is the difference between a VPN and a Remote Desktop Connection ?
Remote Desktop Connection refers to a connection to another computer where the connecting computer takes control of the connected computer, operating it as if it were its own desktop.
VPN or Virtual Private Network is an IP-based connection to another computer or network, which allows the connecting computer access to drives and files in the connected computer or network.
