When upgrading from a version to v15.1.0 or later, the system might report 'Illegal entry point' and 'Illegal flow to URL' messages.
1. Upgrading from a version prior to v15.1.0 to a v15.1.0 or higher. 2. The policy contains flows, and illegal flow and illegal entry point are configured.
You can use either of the following workarounds: -- Turn off blocking from the illegal flows violations before upgrading. Then wait for some time until the violation alarms no longer appear. -- Use an iRule that unblocks these violations and deletes the ASM cookies when that happens.
