When clients connected to IPV6 networks, Unified Agent LE (Local Enforcement) fails to filter, allowing clients to violate the configured AUP (Acceptable Usage Policy) created by the administrator.

Currently there is a Feature Request to provide support for Unified Agent (LE) versions. At this time, Unified Agent (LE) will only filter requests on an IPV4 network. If you are looking to utilize Unified Agent (LE) within an IPV6 network, note this behavior and look for methods to do a conversion from IPV4 to IPV6 and back, if required.
