2015年4月14日 · You should use TCP ports 389 and/or 636. Port 636 is for LDAPS, which is LDAP over SSL. Encryption on port 389 is also possible using the STARTTLS mechanism, but in that case you should explicitly verify that encryption is being done. Microsoft's KB article says: Start TLS extended request. LDAPS communication occurs over port TCP 636.

2015年12月4日 · @BrianZ This is Windows 7/8/10 and to get there, just open Start Menu search for "Firewall" and click on "Advanced Settings" on the left-side panel, click on Inbound Rules on left-side panel and on the main panel find Remote Desktop - User Mode (TCP-In) and Remote Desktop - User Mode (UDP-In) and Allow edge traversal for both of them.

2016年2月2日 · The new default start port is 49152, and the new default end port is 65535. Therefore, you must increase the remote procedure call (RPC) port range in your firewalls. If you have a mixed domain environment that includes a Windows Server 2008 R2 and Windows Server 2008 server and Windows Server 2003, allow traffic through ports 1025 through 5000 ...

If the firewall were blocking any of those ports, the STATE returned would be filtered instead of open or closed. That only verifies the firewall rules, though. It doesn't verify that the service is necessarily running on the port, or that it is operating correctly. For that, you'd have to run a check that understood the service you were checking.

2012年4月5日 · Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server. There are also ports for Cluster and client status (Port 1110 TCP for the former, and 1110 UDP for the latter) as well as a port for the NFS lock manager (Port 4045 TCP and UDP). Only you can determine which ports you need to allow depending on which services are needed cross ...

2020年7月29日 · Well when it comes to firewall it's mostly about enabling the related ports. I suggest something like this: For workgroup-joined machines, your best option is to locate the firewall rules in the Windows Firewall with Advanced Security tool that match the remote management tool(s) you wish to use and selectively open them to …

2015年2月19日 · The best way to check if a port is blocked is to do a port scan from the client machine. There are many ways to do a port scan but since you mentioned being on Windows then I will suggest the Microsoft command line utility PortQry and the Graphical version PortQryUI. To test all open ports: portqry.exe -n #.#.#.# To test a specific port:

Protocol: UDP, port 4500 (for IPSEC NAT-Traversal mode) Protocol: ESP, value 50 (for IPSEC) Protocol: AH, value 51 (for IPSEC) Also, Port 1701 is used by the L2TP Server, but connections should not be allowed inbound to it from outside. There is a special firewall rule to allow only IPSEC secured traffic inbound on this port.

The 'connection timed out' message is there because the connection SYN packet didn't receive either an ACK or a RST. That could be because the firewall is still blocking the port, the service isn't actually listening there (the FW still ate the RST packet), or the service refused to talk for some reason (the FW still ate the RST packet).

2017年9月14日 · This is the matter: since the firewall is stateful, if the server is the responsible of initiating the communication through the dynamic ports, then the rule should be unidirectional with source=server and destination=client. If the answer is sent through 135, then the responsible of initiating the communications to the dynamic ports is the client.
