Batch Configuring Forwarding Rules

Use Cases

Tencent Cloud EdgeOne allows you to configure multiple forwarding rules for an L4 proxy instance. This document describes how to import and export multiple forwarding rules at a time.
Note:
1. You can import up to 2,000 forwarding rules at a time. Each L4 proxy instance supports up to 2,000 forwarding rules.
2. The fields in batch imported forwarding rules are not case-sensitive.
3. The imported forwarding rules cannot use the forwarding ports of existing forwarding rules.
