Hi Digent Verma , what if i use a computer with 2-3 Lan cards , install Win2k3 Server , install Routing and Remote Access and use it as a Router ?
Sorry but I seem to have lost you there.And oh you cant install "routing".Basically a router is a hardware device which acts as a gateway also may have features such as Packet filtering,SPI...
Do you want to use a single machine as entirely for routing purposes?
Then why install win2k server dude.If you have a old machine lying around ,even a 486 will do
then may I suggest you freeware solutions based on linux.These distros are built-in with features such as firewall,port blocking....Exactly what you need if you dont want to invest in a hardware router.
1.Clarkconnect-This one is very good considering the features it offers.Highly recommended by MVP's.
2.IPcop-Another good distro which is feature rich.
3.Smoothwall-Cool with lotsa options.
Configuring them is not hard if you go through the forums & documents posted at their respective sites.Get a few lan cards & a hub/switch whichever suits your pocket & you are on your way.
Also the new routers also have options to scan for virus a and email stuff. Which makes it basically a pc anyway.
Are you kidding me?Can you atleast give me the company url which sells routers which scan for virus to backup whatever you posted?
