Enabling Internet Border Traffic Protection
CFW protects Internet border traffic by protecting EIPs. After EIP protection is enabled, your service traffic will pass through CFW. By default, all traffic is allowed.
To use CFW to protect traffic, you also need to configure access control policies or enable IPS. For details about how to configure access control policies, see Adding a Protection Rule. For details about IPS, see Configuring Intrusion Prevention Policies.
Constraints
- Currently, IPv6 addresses cannot be protected.
- An EIP can only be protected by one firewall.
Impacts on Services
Enabling or disabling EIP protection does not interrupt services, ensuring smooth traffic switchover.
- For details about how to edit a protection rule, see Managing Protection Rules.
- For details about how to edit a blacklist, see Managing the Blacklist and the Whitelist.
Enabling Internet Border Traffic Protection
- Log in to the management console.
- Click
in the upper left corner of the management console and select a region or project.
- In the navigation pane on the left, click
and choose Security & Compliance > Cloud Firewall. The Dashboard page will be displayed.
- (Optional) Switch to another firewall instance: Select a firewall from the drop-down list in the upper left corner of the page.
- In the navigation pane, choose Assets > EIPs. The EIPs page is displayed. The EIP information is automatically updated to the list.
- Enable EIP protection.
- Enable protection for a single EIP: In the row of the EIP, click Enable Protection in the Operation column.
- Enable protection for multiple EIPs: Select the EIPs that you want to enable protection and click Enable Protection above the list.
NOTICE:
- Currently, IPv6 addresses cannot be protected.
- An EIP can only be protected by one firewall.
- On the page that is displayed, check the information and click Bind and Enable. Then the Protection Status changes to Protected.
NOTE:
After EIP protection is enabled, the default action of the access control policy is Allow.
Related Operations
- Disabling EIP protection
- To disable an EIP, click Disable Protection in the Operation column of the EIP.
- To disable multiple EIPs, select them and click Disable Protection above the table.
- Enabling automatic protection for new EIPs: Enable Auto Protect New EIP above the list. Protection will be automatically enabled for new EIPs, and EIP traffic will pass through and be protected by the firewall.
- Exporting the EIP list: Click Export above the list and select an export scope.
- To protect the EIPs of other accounts, see Multi-account Protection.
Follow-up Operations
- To implement traffic control, configure a protection policy. For details, see Adding an Internet Boundary Protection Rule or Adding Blacklist or Whitelist Items to Block or Allow Traffic.
- Allow or block traffic based on protection rules.
- Traffic allowing rule: The allowed traffic will be checked by functions such as intrusion prevention system (IPS) and antivirus.
- Traffic blocking rule: Traffic will be directly blocked.
- Allow or block traffic based on the blacklist and whitelist:
- Whitelist: Traffic will be directly allowed without being checked by other functions.
- Blacklist: Traffic will be directly blocked.
- Allow or block traffic based on protection rules.
