Cisco IOS Firewall Configuration Steps

CBAC configuration steps:

• Choose an interface (inside or outside).
• Configure an ip access list that denies all traffic to be inspected.
• Configure global timeouts & thresholds using the ip inspect commands.
• Define an inspection rule & an optional rule-specific timeout value using the ip inspect name protocol commands.
• Apply the inspection rule to an interface.
• Apply the access list to the same interface as the inspection rule, but in the opposite direction(inbound or outbound)
