How To – Allow Secured Internet Access to Guest Users

Applicable Version: 10.02.0 Build 224 onwards Applicable Models: Wi-Fi Models Only Overview Places like public hotspots and hotels have numerous Internet users that require temporary Internet access just for a few days or hours. Maintaining such users becomes quite a hassle for administrators. Furthermore, applying access restrictions upon these users is difficult. Cyberoam allows the administrator to provide temporary access to Guest Users. This is mostly done via Wireless Guest Access Points by deploying a Wireless LAN (WLAN). A good guest access system ensures reliable and high-performance access to the Internet without the guest having to go through the hassle of reconfiguring his/her PC to connect to the WLAN. A Guest Access Point must segregate internal and guest traffic to provide ironclad security for the organization’s LAN and servers. Since guest access is provisioned on the same network infrastructure carrying internal traffic, this is a significant challenge.

Scenario Create a Wireless Access Point and allow controlled Internet access to Guest Users.

Configuration Configuration is to be done from Cyberoam Web Admin Console using profile having read-write administrative rights over relevant features. This configuration consists of Two (2) parts: 1. Configure Access Point for Guest User 2. Configure Guest User Authentication

Configure Access Point for Guest User Step 1: Create Guest Zone Go to Network > Interface > Zone and click Add to create a new zone using parameters given below.

Step 5: Update Firewall Rule to Secure WLAN Traffic On creation of the GUEST Zone (as shown in step 1), Cyberoam automatically creates default rules allowing traffic from GUEST to WAN as shown below.

How To – Allow Secured Internet Access to Guest Users

Update Default Rule #Guest_WAN_AnyTraffic, to Drop all traffic that hits it. This is required if you want to drop all unauthenticated traffic. Any Guest User trying to access Internet is forced to authenticate enabling controlled Internet Access.

The above steps configure Internet Access Point for Guest Users.

Configure Guest User Authentication Once the Internet Access Point is configured and all unauthenticated traffic is dropped to enforce user authentication, administrator needs to configure the Guest User Authentication settings.

Step 1: Create and Assign Policies to Guest Group Create a Guest Group to implement various policies upon the guest users included in that group. This ensures controlled Internet access by guest users. To create a group, go to Identity > Groups > Groups and click Add to create a new group with parameters given below.

Step 3: Create Guest Users Guest Users can be created in Two (2) ways: 1. Manually (by the Administrator) 2. Automatically Create Guest Users Manually This is the more commonly used method to create Guest Users. To create users manually, go to Identity > Guest Users > Guest Users and click Add Single to create a single user OR Add Multiple to create multiple users simultaneously. Here, as an example, we have created a single user.
