Network Problem

<p><strong>1．</strong><strong>Can ECS change Internet IP address?</strong></p> <p>The Internet IP cannot be directly replaced, but you can first release the ECS bound IP and then apply for Internet IP again.</p> <p><strong>2．</strong><strong>Can the Internet IP address be restored after it is released?</strong></p> <p>No, the Internet IP address cannot be restored after being released and cannot be used anymore.</p> <p><strong>3．</strong><strong>What should I do if there is no network after ECS login?</strong></p> <p>It may be caused by the incorrect configuration of the server security group. You can check the inbound and outbound rules of the server security group to check whether the target, protocol ports, and policies are prohibited.</p> <p><strong>4．</strong><strong>Can the intranet of the ECS be interconnected under different accounts?</strong></p> <p>The intranets of ECS under different accounts are unavailable, and intranet interaction can be achieved through high-speed channels.</p> <p><strong>5．</strong><strong>Are there any restrictions on creating a NAT gateway?</strong></p> <p>Each NAT gateway applies for a maximum of 5 bandwidth packages, and each bandwidth package applies for a maximum of 5 Internet IPs.</p> <p><strong>6．</strong><strong>How to add a route to the expansion network card?</strong></p> <p>For more information, see Expand network card in the operation guide.</p> <p><strong>7．</strong><strong>Can I buy multiple ECSs on the same subnet?</strong></p> <p>Yes, when you buy ECS, you only need to select the same VPC and subnet for these ECSs.</p>
