Traffic to ReadyNAS being blocked
Hello - I am running Symantec Endpoint Protection on my workstation, and it is periodically (regularly) blocking traffic from my ReadyNAS 312. The error message I get is: Somebody is scanning your ...
Thanks, Chetan,
Oddly enough this only happens on one workstation, which is physically connected to the same switch - another workstation further up the network chain with the same anti-virus client has no problems. I would gladly add an exception to my SEP client, but it doesn't allow me to add folder exceptions unless it can connect to the folder (which it can't once the IP has been blocked [which is done as soon as I connect to the computer]).
Honestly, I think it's a question that could be answered by Netgear - are the ports listed in the original post used by any applications or services on the ReadyNAS, and if so, what are they?

I agree that Netgear should be able to provide some info on port use. All the ports on your list are reserved for private use, so its not clear to me why the NAS would be probing them. If you have uPNP enabled as a service, perhaps disable that.
But I'd also accept Chetan's offer to help you analyze. SEP can be quite aggressive on blocking traffic. My client has blocked SVChost outbound, and also blocked my network printer. Unfortunately I don't have the authorization needed to customize its rules/policies. Eventually I found that off network discovery features in the printer solved that particular problem.
Thought I had something there with uPNP, but nope - I only have NFS, SMB and HTTP/S enabled.
This workstation also has PeerBlock installed on it, as it is my RDP landing computer (the only thing that really differentiates it from my other workstations), but the errors and blockage are definitely coming from SEP.
I'd definitely take the help offeredby Chetan, I'm just not sure how I would go about checking it.
Just checked the workstation and it looks like PeerBlock isn't even installed, so that's a non-starter as well.
Just found this... Did Chetan come back to you regarding this?
