Adding an Access Rule

To apply an access rule, perform the following steps.

Detailed Steps

Step 1 Choose Configuration > Firewall > Access Rules.

Step 2 Click Add, and choose one of the following options:

The Add Access Rule dialog box appears.

Step 3 From the Interface drop-down list, choose the interface on which to apply the rule. Choose Any to apply a global rule.

Step 4 In the Action field, click one of the following radio buttons next to the desired action:

•Permit—Permits access if the conditions are matched.

•Deny—Denies access if the conditions are matched.

Step 5 In the Source field, enter an IP address that specifies the network, interface IP, or any address from which traffic is permitted or denied to the specified destination. You may use either an IPv4 or IPv6 address.

For more information about enabling IPv6 on an interface, see the “Configuring IPv6 Addressing” section on page 13-15in the general operations configuration guide.

Step 6 In the User field, enter a user name or group to the ACL. Enter the user name in the format domain_NetBIOS_name\user_name. Enter the group name in the format domain_NetBIOS_name\group_name.

You can configure access rules based on user names and user group names rather than through source IP addresses. The ASA applies the security policies based on an association of IP addresses to Windows Active Directory login information and reports events based on the mapped user names instead of network IP addresses.

See the “Configuring Identity-Based Security Policy” section on page 38-16in the general operations configuration guide for more information.

Step 7 To browse for a user name or user group, click the ellipsis (...) button. The Browse User dialog box appears.

Step 8 In the Destination field, enter an IP address that specifies the network, interface IP, any address to which traffic is permitted or denied from the source specified in the Source field. You may use either an IPv4 or IPv6 address.
