Hi all,
want to know what is a 128 bit firewall I know one person who is writing it. But i dont understand, a firewall is either host based or network based but all it do is read the packets and filter them so where the question of 128 bit encryption or security comes in?

any one could say something on it?

This would be the level of encryption for the VPN that the firewall supports. Site to Site of client to site.

I not sure of best way to answer this, but here goes. 128 is highest encryption there is right now. You have basically a door and a key. You have to give the key to who is dialing in or however they do it on there network. Say you send a document into work and somebody intercepts it. They can't open it unless they have the key, also when something is sent to the network it (firewall) won't let it in unless it has the key. I read an article than stated that even if you could intercept actual 128-bit key it would take like 100 or 200 years to decrypt it. I'm not sure if this helped you. I know the concept and how to use, but not to good at describing it.
