This topic describes the frequently asked questions (FAQ) about networking for WUYING Workspace Enterprise Edition.
Index
Can I use an IPsec-VPN connection to connect my on-premises data center to a cloud computer?
Yes, you can. You can connect to cloud computers only through IPsec-VPN, SSL-VPN, Smart Access Gateway (SAG), or Express Connect (leased lines).For more information, see Connect to an enterprise network.
What do I do if my cloud computer cannot access the Internet?
Symptom: The cloud desktop cannot access the Internet.
Cause 1
The cloud computer does not have Internet bandwidth enabled.
The premium bandwidth plan that is attached to the WUYING office network (previously known as a workspace) is not in the In Use status.
Solution
Enable Internet bandwidth and attach it to the office network of the cloud computer.For more information, see Manage Internet bandwidth. If Internet bandwidth is already enabled, check its status.
Log on to the WUYING Workspace Enterprise Edition console.
In the navigation pane on the left, choose .
On the Premium Bandwidth page, find the premium bandwidth plan and check its Status column:
In Use: This is the normal status.
Expired/Overdue: In the Actions column, click Renew and follow the instructions to complete the renewal.
Released: On the Premium Bandwidth page, click Enable Premium Bandwidth to enable a new premium bandwidth plan.
Creating: Wait a moment. After the plan is created, the status changes to In Use.
Cause 2
If the office network has Internet bandwidth enabled, the cloud computer may not have permission to access the Internet.
Solution
Enable Internet access control for the office network.
Log on to the EDS Enterprise console.
In the left-side navigation pane, choose .
On the Office Network page, find the office network of the cloud computer and go to the office network details page in one of the following ways:
In the Actions column, click Modify Internet Access Control.
In the Office Network Name/ID column, click the office network ID.
On the office network details page, in the Internet Bandwidth section, set Internet Access Control to All Cloud Computers In The Office Network Can Access The Internet. You Can Configure A Denylist..
Cause 3
A policy may be restricting access if the cloud computer still cannot connect to the Internet after you confirm that the office network has Internet bandwidth and the cloud computer has the required permission.
Solution
Check whether a policy is restricting access.
Log on to the WUYING Workspace Enterprise Edition console.
In the navigation pane on the left, choose .
On the Policies page, find the policy that is attached to the cloud computer and click the policy ID to go to the policy details page.
On the policy details page, in the Policy Settings section, perform the following checks.
Choose .
In the Security Group Control section, click Outbound. Check for any security group rules that restrict outbound network traffic.
In the Domain Name Access Control section, check for any access policies that restrict domain name resolution.
Choose Cloud-side Network Redirection. Check whether cloud-side network redirection is enabled.
If restrictive rules exist, remove them, save the changes, and then disconnect from and reconnect to the cloud computer. Then, check whether you can access the Internet.
Cause 4
If the issue persists after you confirm that the office network has Internet bandwidth, the cloud computer has the required permission, and no policies are restricting access, check the following scenarios.
Proxy server is enabled
Detection method
Read the registry key value in the system to determine whether a proxy is enabled.
Log on to the WUYING Workspace Enterprise Edition console.
In the navigation pane on the left, choose .
In the top navigation bar, select the destination region.
On the WUYING Workspace Enterprise Edition page, find the cloud computer to which you want to send a remote command, and send the command in one of the following ways:
In the Actions column, click More, and choose Send Remote Command.
Click the cloud computer ID, choose the Command Execution Details tab, and then click Send Remote Command.
In the Send Remote Command dialog box, enter the following command and click Execute.
$ProfileLists=Get-ChildItem -Path "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" -Name; $SidLists=$ProfileLists | Where-Object { $_ -like "S-1-5-21-*" -and $_ -notlike "*-500" }; Foreach ($Sid IN $SidLists) { $a=(Get-ItemProperty -ErrorAction SilentlyContinue -Path "Registry::HKEY_USERS\$Sid\Software\Microsoft\Windows\CurrentVersion\Internet Settings" -Name ProxyEnable).ProxyEnable; if ($a -ne 1) { Write-output "proxy is off" } else { Write-output "proxy is on" } }
Fix
If a proxy is enabled and you cannot access some websites, consider disabling the proxy.
Abnormal network interface card status
Detection method
Check the network interface card (NIC) in the cloud computer:
Check whether the IPv4 protocol is enabled for the NIC.
Check whether the NIC is disabled.
Check whether the hop count of the management NIC is greater than the hop count of the user NIC.
Fix
Use WUYING Steward to fix the issue. For more information, see Use WUYING Steward.
Network interface card status abnormal
Detection method
Check the route table in the cloud computer:
Read the route table.
Check whether the default route 0.0.0.0 exists.
Check whether the management service routes 100.64.0.0 and 100.100.100.200 exist.
Fix
Use WUYING Steward to fix the issue. For more information, see Use WUYING Steward.
Security software or VPN software is installed
Detection method
Check whether security software or VPN software is installed on the cloud computer. WUYING Workspace detects only common security software and VPN software.
Fix
If the software affects access to some websites, consider disabling the software and retry.
Firewall is enabled
Detection method
Check whether the firewall is enabled on the cloud computer.
Fix
Disable the firewall. The following steps use a Windows OS as an example.
Go to .
In the navigation pane on the left, click Turn Windows Defender Firewall On Or Off.

Log on to the EDS Enterprise console.
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Premium Bandwidth page, find the target premium bandwidth plan and click Upgrade/Downgrade in the Actions column.
In the Upgrade/Downgrade Premium Bandwidth panel, in the Bandwidth section, adjust the bandwidth as needed and click Confirm.
Why can't I ping a cloud computer from a public IP address?
By default, cloud computers deny all inbound access and allow all outbound access. Therefore, you cannot ping a cloud computer from a public IP address.For more information, see Differences between WUYING Workspace and Elastic Compute Service (ECS).
Why can't I access a cloud computer after I enable the firewall?
Enabling the firewall may close some ports, preventing you from logging on to or connecting to the cloud computer. In this case, you must manually open the required ports to ensure that your services run as expected.For more information, see Service port requirements for cloud computers.
