Chapter 23 Adding a WebtypeACL
Using Webtype ACLs
Adding a Webtype ACL and ACE
You must first create the webtype ACL and then add an ACE to the ACL.
Note Smart tunnel ACEs filter on a per-server basis only, so you cannot create smart tunnel ACEs to permit
or deny access to directories or to permit or deny access to specific smart tunnel-enabled applications.
To configure a webtype ACL, perform the following steps:
Step 1 Choose Configuration > Remote Access VPN > Clientless SSL VPN Access > Advanced > Web
ACLs.
Step 2 Click Add, and choose one of the following ACL types to add:
• Add ACL
• Add IPv6 ACL
The Add ACL dialog box appears.
Step 3 Enter a name for the ACL (with no spaces), and click OK.
Step 4 To add an entry to the list that you just created, click Add, and choose Add ACE from the drop-down list.
Step 5 In the Action field, click the radio button next to the desired action:
• Permit—Permits access if the conditions are matched.
• Deny—Denies access if the conditions are matched.
Note The end of every ACL has an implicit deny rule.
