I cannot download the ZyWALL's firmware package.
The ZyWALL's firmware package cannot go through the ZyWALL when you enable the anti-

You can upload the firmware package to the ZyWALL with the option enabled, so you only
need to clear the Destroy compressed files that could not be decompressed option while
you download the firmware package. See

I changed the LAN IP address and can no longer access the Internet.
