One more management feature, inter VLAN routing office network in the components, which generally are not available between one another still they are routed to connect.

Firewalls, Switches, Routers and VPN

November 25th, 2011 4 comments

Are you learning about how the business uses the networking systems? Well, you may be surprising why there is much essentiality on the difference between a switch, routers, firewall, and VPN networking systems. These four networking systems are basically designed to use for the Internet protocol. Keep in mind that these genres of networking systems are having different functionalities.

So, you need to understand the functionality and utilization process of these networking systems. Now, these networking systems are becoming essential for numbers of business. So, it is the perfect option for you to download the trail version of these networking systems online. You can also collect some information about these switch, routers, firewall, and VPN networking systems from previous users.

I am not saying this is not done and you may buy the big as well as expensive, chassis based, the Cisco 6500 series switch & have all the functions on various blades of switch. This is good for the larger business with the group of administrators however to the medium size business as well as single network administrator, lots of times, it is the scary thought. Remember that for the medium or else large size business, the integrated home devices will not work as they will not give all these features needed. Standalone routers, firewalls and switches, have a lot of more features than the integrated devices do. However, what is difference between the devices anyway? Let us now cover three most famous devices.

Router

The router is the hardware device as well as has function of the routing packets between the networks. The router works at the Layer 3 of OSI model –Network Layer. It is a layer that IP protocol works. Most of the routers now are the IP routers, which examine source as well as destination IP addresses of every packet, look up destination of packet in router’s IP routing table, as well as route, which packet on the way.

Firewalls, Switches, Routers and VPN – It’s All About Selecting the Best Networking Device!

September 21st, 2011 No comments

This time almost everyone wants to bring more customers’ attraction for their business. It can be possible through a secure networking device. However, selecting one of the best networking business is a risky job. So, you need to look for these networking systems like firewalls, switches, routers and VPN through which you can easily start your business.

There are so many users using these genres of networking systems for their business. It is the right option for you to get one of the best networking systems from online media. Let’s look for these networking systems like switches and routers and their function which are briefly discussed at the online media.

Cisco RV042 features six fast Ethernet ports and it supports around 50 separate simultaneous VPN, the Virtual Private Network for the telecommuters & branch offices connections. Cisco VPN software also includes the built in firewall & optional viruses, spam, as well as malware protection, which can help to keep the business safe.

That received actually solid customer reviews in Amazon where you may order at the discount. EtherFast Cable or DSL Firewall Router with the 4 Port Switch or VPN Endpoint is a perfect solution to connect the group of the PCs, like Small Office or Home Office, to the high speed broadband connection or 10/100 Ethernet backbone.

So, everything is upgraded to the Gigabit, probably the couple eight ports and three or so five port switches unless I would like to add more of drops to the rooms. Any suggestions on 5 & 8 port Gigabit switches? As for server, they are using that mostry as the file server, however will need RAID 0+1 on that.

I am planning on running the Server 2008 Foundation and maybe Win7 Pro 64 on it as they may not have to use that as the domain server – they are staying in the workgroup. What are pros and cons of the Server 2008 Foundation and Win 7 Pro? They will need a server to stay the ftp server for the clients for sending them the large files.

VPNC for Ubuntu!

October 20th, 2009 1 comment

People coming from the Windows world are used to using Cisco VPN client to login to their corporate network.  So when they make the transition over to Ubuntu, they’re somewhat puzzled at the complexity of getting Cisco VPN client working.

It’s obviously not as straightforward as it is on Windows platform but there also has been cases of kernel panics using the Cisco VPN client on Linux.

For those who are looking for an alternative, I’ve got good news.  I came across VPNC recently and it only took me a few minutes to get it installed, configured and get connected to my job’s corporate network.

Supported Platforms:

  • Linux (i386/ppc/zaurus tested)
  • NetBSD (i386 tested)
  • FreeBSD (CURRENT of 23.11.2003 tested)
  • OpenBSD (CURRENT of 18.04.2004 tested)
  • DragonFly BSD
  • Darwin / Mac OS X
  • Solaris (7 works, 9 only with –natt-mode forced)
  • Windows / Cygwin

As you can see it supports more than just Linux but I haven’t yet tested on any other in the above list to make sure.

Quick Setup:

$ sudo apt-get install vpnc
Convert your existing PCF file (if you have any) to vpnc recognized format using this perl script: http://svn.unix-ag.uni-kl.de/vpnc/trunk/pcf2vpnc
$ wget http://svn.unix-ag.uni-kl.de/vpnc/trunk/pcf2vpnc
$ chmod +x pfc2vpnc
$ ./pcf2vpnc orig.pcf vpnc.conf
$ sudo vpnc vpnc.conf

That’s it!  Five easy steps to install, configure and connect to your network.  If you have Kubuntu, you can install kvpnc which by default allows you to use the original PCF file for configuration, so no need to convert here.  I haven’t tested this myself so I can’t say for sure it works.

Go ahead, give it a try.  Read the doc that comes with the source pkg to setup a configuration from scratch.
