Create Firewall
Create Firewall
- In All Products -> Basic Network UNet -> Internet Firewall page, click Create Firewall to create one.
- On the creation page, configure firewall rules according to your business scenario, then click Next to confirm the entered information.
- Click Confirm to complete the creation of the firewall.
Edit Firewall Rules
Currently, the firewall protocol supports "TCP", "UDP", "ICMP" and "GRE" protocols.
- By default, the firewall rejects other accesses except for entered entries.
- The firewall does not support duplicate rules. If the protocol, port, source address, and action are repeated, they are judged as duplicate rules. Duplicate rules will cause errors in operation.
- On the firewall details page, select the firewall rules that need to be edited, configure according to the following information, and then click Confirm.
| Configuration | Description |
|---|---|
| Basic Protocol | Specify TCP: User-defined TCP protocol port Specify UDP: User-defined UDP protocol port Full-Port TCP: All TCP ports Full-Port UDP: All UDP ports GRE: GRE Protocol ICMP: ICMP Protocol |
| Quick Rule | FTP: TCP Port 21 HTTP: TCP Port 80 HTTPS: TCP Port 443 PING: ICMP Protocol OpenVPN: UDP Port 1194 PPTP: TCP Port 1723 RDP: TCP Port 3389 SSH: TCP Port 22 |
| Port | The local port accessed by the source address, with the port range of [1-65535]. |
| Source Address | The source address of the network data packet accessing the cloud platform host resources, supporting both IP address and network segment. IP address and network segment are separated by commas (supporting IP and network segment number ≤10), such as "10.0.0.1,192.168.0.2/32". |
| Action | When the firewall takes effect, it includes two actions for data packet processing, namely "Accept" and "Reject". |
| Priority | When adding rules within the firewall, the rules are executed in order of priority, with each rule includes "High", "Medium", "Low" three levels. |
| Remarks (Optional) | Remarks can be added to each rule for easy rule management and search. |
Delete Firewall Rules
The firewall rule supports deletion of a single rule or batch deletion.
The firewall needs to keep at least one rule, so the "Delete" button is not available when all are selected.
- On the firewall details page, select the firewall rules that need to be edited and click Delete in the operation field. You can also select multiple firewall rules that need to be deleted and click Delete.
- In the pop-up Delete Firewall Rule prompt box, click Confirm to complete the deletion of the firewall rule.
