N66U - How to block all outgoing traffic from spec. IP?

[dimman]

Hi,

I'm wondering how I configure my N66U to block all outgoing traffic from my NAS (specific IP) on my network?

I've googled, but haven't come up with anything conclusive.

Would appreciate some help

Either use Firewall > Network Services Filter or Parental control

I went with Parental Control (as I don't know the target IP or the port range for Network Services Filter).

Will the use of the Parental Control-feature allow my NAS to accept incoming traffic (as per my question in the opening post)? The way it looks, at least, it blocks all traffic - in and out?

Yes it will block all traffic, I thought that was what you wanted. Any meaningful communication across the internet requires traffic to flow in both directions. If you block traffic in one direction it will have the same effect as blocking it in both.

To put it another way, if you're blocking all outgoing traffic:-
a) If someone on the internet sends a request to your NAS they won't get a response back.
b) If your NAS tries to talk to the internet (to get updates for example) it will be blocked.

Of course for case a) you don't need to block anything at all if you haven't setup the router to port forward to your NAS.

What are you trying to achieve exactly?

Hi,

I noticed traffic out of my NAS that I believe shouldn't be there. It was traffic between 20 and 60kb/s. I'm not able to see which process was sending the data so I wanted to stop all outgoing traffic. I,however, want to be able to download stuff, so maybe I'm just screwed?

Unless you give us specific details about your setup it would be impossible to determine whether there is a problem.

Some NAS's can run lots of different services, like torrent clients, media servers, backup clients, ftp servers, samba servers, cloud services. If I were you I would turn all of them off and then turn them back on one at a time. That way you might be able to determine (or at least exclude) for source of the traffic.
