    Troubleshooting Access Problems Using Packet-Tracer

    Troubleshooting access problems through a firewall is often very difficult, especially when speed to resolution is critical. Errors in long complex ACLs can be easily overlooked, and access failures caused by NAT, IDS, and routing make the problem even more difficult. Cisco has released an incredible new feature in ASA software version 7.2(1) that virtually eliminates the guesswork. Packet-tracer allows a firewall administrator to inject a virtual packet into the security appliance and track the flow from ingress to egress. Along the way, the packet is evaluated against flow and route lookups, ACLs, protocol inspection, NAT, and IDS. The power of the utility comes from the ability to simulate real-world traffic by specifying source and destination addresses with protocol and port information.
