USG 50 Block a range of external IPs

Hi @pmkdatabase

You can create IP range in Configuration > Object > Address first.

And then apply this object to your Firewall rule. (Configuration > Firewall)


Note: If you select "ZyWALL" zone in the rule. It means firewall will block the traffic those to USG local service.(e.g. HTTPS/SSH/TELNET/FTP....etc)
