Why cannot the VCN3010 be accessed from the intranet when it is deployed on the extranet and is configured with network address translation traversal (NAT traversal)?

Check whether NAT is configured for all the VCN3010s that are deployed on the extranet. Log in to the OMU portal of each VCN3010, choose Local Configuration > Server Configuration, and ensure that the value of each NAT IP is correct. Check whether the fault is rectified. If the fault persists, contact Huawei technical support engineers for assistance.
