    Hi @Nicola_Santalucia

    Regarding our remote session, while attempting to access https://pti.regione.sicilia.it/ we observed that only a TCP SYN packet was sent to the website server. However, the website server did not respond with any TCP SYN-ACK to the PC. Therefore, please bypass the USG Flex 100 and connect directly to the ISP router to see if you can access those websites or not. Thank you.

    Hi @Nicola_Santalucia

    Per our discussion on the private message. It seems the root cause is related to the website blocking your public IP. Thanks.

    Hi @Nicola_Santalucia

    Whenever you cannot access https://admin.aruba.it/ , what kind of blocked log can be observed on Monitor > Log > View Log? Thanks.

    Hi, thank you for your response. I don't have anything in the Logs about Aruba.
