Information About Extended Access Rules
This section describes information about extended access rules and includes the following topics:
• Access Rules for Returning Traffic, page 34-4
• Allowing Broadcast and Multicast Traffic through the Transparent Firewall Using Access Rules,
page 34-5
• Management Access Rules, page 34-5
Access Rules for Returning Traffic
For TCP and UDP connections for both routed and transparent mode, you do not need an access rule to
allow returning traffic because the ASA allows all returning traffic for established, bidirectional
connections.
