Hi, we are trying to configure the Flex 500H behind a Router with DMZ. The router has IP 192.168.2.1 configured and has a DMZ configured to 192.168.2.2.2 which is the Zywall. The problem is that we do not see anything in the log, opening port 21 for example to test. Is there anything else to configure?

    I take it your doing double NAT? does your ISP router do static routes? as there be a better way

    The FLEX in double NAT needs to have a Virtual Server NAT rule for port 21 and passive port range

    Hi @GIAGroupIT,

    The problem is that we do not see anything in the log, opening port 21 for example to test.

    May I know what you expect to see in the log? Where did you check the log?

    We are not sure what your true problem is. Could you share more details with us?
