  • When you get 'Invalid License' error.

    It's not actually a license error, but rather an issue related to a connection problem. NxFilter needs to access the internet using TCP/80, TCP/443, and UDP/123. If any of these ports are blocked, you may encounter this problem. You need to ensure that these ports are open for outbound traffic.

    If you use v4.6.7.9 or later, you can use the following command to check the ports.

    Code:
    /nxfilter/bin/runcmd.sh chkports
