I encountered the following situation:
I have a PPPoE Internet connection.
When I try to use Web proxy in “Transparent mode” or “Transparent with SSL” in conjunction with “Block HTTP and HTTPS ports”, after I press “SUBMIT” button I receive an error message at the end of the task (please see the “Task error” attached picture).
After many tries, I observed that the error appear only if I have PPPoE connection (please see attached picture). If I configure NIC with fixed IP, I have no errors.
Thank you in advance for help!
