(windows system) Today, on a machine (server) in the local area network, FileZilla is used to configure the FTP server. Everything is normal when accessing the server locally, but other machines (clients) cannot connect, and the client can ping the server address. , the firewall is completely closed, or the firewall is turned on, and the corresponding inbound and outbound rules are set, and the server also sets outbound rules or closes the firewall, but still cannot connect to the FTP server;
Finally, I checked the "Network Sharing Center-Change Adapter Settings" interface in the client control panel and found that there is a redundant network adapter, and the gateway of this adapter is the same as the gateway of the network adapter used by this machine, and then disabled the redundant adapter. ,everything is normal.
The image below shows a disabled network adapter (virtual machine virtual network adapter).
