Hello everyone.

I have a D-Link DNS-323 in my company, and people which are "outside" internal network cannot ping or access services provided by this NAS or any other Linux machine.

In our case, imagine that a client has an IP of 10.150.12.1 and has a permanent route set on routing table which tells Windows to access our internal network (192.168.0.0), throughout a certain gateway. This client will not be able to access NAS, but it can access another Windows-based machine.

If I setup a VPN connection everything works fine, but not with this "direct link (route)" set.

Have someone experienced this before?

Thanks for your collaboration.

Best regards,

Bruno Martins

You appear to have a routing or firewall issue - as evidenced by the fact that you can do what you want over a VPN.

Strictly speaking - many of the issues involved are outside of the scope of this forum since they are not related to the DNS-323 - but let's see if we can at least touch on them.

First - does the DNS-323 have the correct default gateway set?  If that "certain" gateway through which the 10.150.12.1 client reaches the 192.168.0.0 network is not the default gateway for the 192.168.0.0 network, when the DNS-323 replies, that reply may be sent to the networks default gateway and may not be returned to the requesting client.

Second - and just as a matter of security - whilst you haven't actually stated that you are trying to access the DNS-323 across the internet, you are trying to access it from outside the internal network, so there is a possibility that you are trying to allow access from an external network - the SMB protocols that are used to access the DNS-323 are not particularly secure and were never intended for use across the internet - are you sure you wouldn't be safer using a VPN?

Thanks mate!

Problem was precisely on the gateway.
