If the Internet boundary switch is not enabled for an asset, will the login protocol port of the asset be blocked?

If the Internet boundary switch is not enabled for an asset, it typically means that the asset is not directly exposed to the public Internet. In this case, the login protocol port of the asset may not be accessible from external networks, but whether it is "blocked" depends on the network architecture and security policies in place.

For example:

• If the asset is located in a private network (e.g., a VPC) and there is no NAT gateway, VPN, or other connectivity method configured, external users cannot reach the login port (e.g., SSH on port 22 or RDP on port 3389).
• If the asset is behind a firewall or security group that restricts inbound traffic, the port may be effectively blocked even if the boundary switch is enabled.

In cloud environments, services like Tencent Cloud's Virtual Private Cloud (VPC) can help manage network boundaries. If you need secure remote access to assets without exposing them directly to the Internet, you can use Tencent Cloud's Bastion Host or VPN Gateway to establish secure connections while keeping the login ports inaccessible from the public Internet.

If the boundary switch is disabled, it usually implies that the asset is not allowed to communicate with external networks, which would block the login protocol port unless alternative access methods (like internal networks or VPNs) are configured.
