TencentDB for Redis does not support direct access over a public network, but you can use a CVM instance with a public IP to access a Redis instance over a public network through port forwarding.
Port forwarding with iptables is not stable, so we do not recommend this public network access solution in a production environment.
The CVM and TencentDB instances must be under the same account and in the same VPC in the same region, or both in the classic network.
