Hi, Folks, I knew there are some big changes about SMB server and clients, the SMB sharing on IPv4 can work fine for me too. But the SMB sharing on IPv6 cannot work fine. After checking the TCP ports with IPv4, the port 139 is closed, and I only can telnet with port 445. For IPv6, both port 139 and 445 are all closed. Could you give more detail information about it? Or any solution to fix it? Thanks & Best Regards! Hao
