Well, what do you actually mean? There are plenty of ways to alter packets. Any routing device does, and a firewall generally does even more. A firewall may also: Terminate and initiate VPN connections, extracting packet from encapsulation envelopes Change header, sripping or altering some data, doing, say, tcp resequencing Change data portion Terminate and initiate whole connection on clients behalf (like proxy firewalls do) Something else that did not come to my mind yet On Wed, Nov 14, 2007 at 02:58:37PM +1100, Kelly Robinson wrote:
Some firewalls, after receiving a packet, generate a new packet and populate it with data from the original, rather than forwarding the same packet that was received. What are the advantages and disadvantages of this approach? And does anyone have any examples of any firewalls that do this on the market?
