Network Security

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. Does the PIX do this?Thanks - K

Am in a spot of bother with getting my SNMP management station (running Solarwinds) to poll a PIX501 firewall at a remote location connected via VPN. The remote PIX501 had its peer changed from the PIX535 to a VPN Concentrator that sits side-by-side ...

Regarding Exchange7, it has been recommended for optimal Direct Push performance that we should increase the time-out value on our PIX525 firewall from the default to 15 to 30 minutes. Could you let me know how I determine the default value at presen...
