Introduction to Firewall

The Internet Firewall (UFirewall) is a software firewall provided specifically for products such as cloud hosts on the SurferCloud cloud platform.
Users can configure the Internet Firewall on the console, without the need to log in to the resource instance for adjustment, to achieve control over the Internet access of resources.
The Internet Firewall supports quick operations such as batch resource switching and copying.
The rules of the Internet Firewall are directly applied to various Internet gateway entrances, without occupying host computing resources.

Product Limitations

The total number of rules for a single firewall is limited by the storage limit of the backend encoding text (notes will also occupy storage). In addition, for performance considerations, the number of rules for a single firewall is also limited to no more than 1000.
