Same Subnet Mask as computer = Must?
« on: December 07, 2009, 10:21:50 AM »

Hi, I bought 2 of DNS 323, and installed WD 1,5TB in one i got it as Raid 1 and the other one as single drives.
But the weird thing is that i could not connect them as a drive. In the beginning of the adventure (just bought them) it happened some times it worked and some times not. Didnt figured it out how it worked and tried all the things i was reading could help. But nothing helped. I could access it by setting up a a new network location and connect to the unit via FTP, and also via the web interface. But now i tried to connect the cable direct to the unit from my computer. and set the computer IP to be 192.168.0.12 It will work and I could connect Havent tried in the network if more then myself could connect to the unit at the same time but I guess it would work. It the computer and the 323 unit are set to DHCP receive IP this will not work because its not in the same sub net mask. So how did you all set this up? In my home I got fibre in to the house and then just a Router to share the internet connection. And because of this it will be different IP and subnet masks and then it doesnt work. Either with IP and the units name.

I tried with the easy serch tool, "net use x: \\192.168.0.32\Volume_1 /user:admin" But it doesnt matter in this case. So whats the problem or is the one of the fabulous features. It must be the same Subnet to be able to set it up?

All the devices on your network should have the same subnet mask.  Why would you want them not to?

I have a DNS-321 and a DNS-323 on my network, I've configured them with static IP addresses, and they've worked that way for a long time.  Once the NAS is configured for your network, you shouldn't have to fool with it. 

You can also use the DHCP client capability and allow it to obtain it's IP address from your DNS Server (typically your router).  I prefer a static address for any servers, so my network printers and NAS units all have static IP addresses.

What is the base address of your router?  If this is Verizon FiOS, it's probably 192.168.1.1 for an Actiontec MI424WR.

The case is that the router only share the internet connection and nothing else. Im not using it as DHCP, and its just because im lazy maybe, but have a couple of server running and then they got a public IP and I don't have to do anything. And because I get the IP from my ISP and they got a lot of IP, with different subnet.  Can i set anything in the .host file to point the IP and dns to this unit? Another reason why i dont want a static IP is because i use a couple of the laptops in the network in different nets. I bring them in to other settings and then my IP and my settings from home doesn't work any more.

Edit: My default gateway and the IP for the router would have been 192.168.0.1 (is a netgear) could set it to whatever. Maybe I should buy a router that could set one specific MAC/unit to get / not get IP from DHCP and then the rest get it from ISP. Anyone know a router with these kind of possibilities?

That brings the picture clearer.

There is NO WAY you want your NAS boxes sitting on a public IP address!  Most of the time, multiple public IP addresses don't have file sharing capability between them anyway, not that anyone in their right mind would enable it if they did!  That would be a security hole that you can drive a tractor trailer through!

I suspect you need to rethink the whole network topology, it sounds like somewhat of a kludge right now.  It also sounds like security is nonexistent.  I think a network diagram would probably be a good start to understanding exactly what you have now.

If you'd like to discuss this further, I'd suggest a more appropriate location.  I spend a lot of time at www.techguy.org, and we have some crackerjack networking folks in our Network forums.  I don't see the support forums for the DNS-323 as the ideal location. :)

Ok, I get it and sure, havent really had the security as the most important question. But as my last question here. Couldnt the 323 share anything to anyone just because of the differences of the subnet. I mean the computers doesnt have any problem doing it. I feel stupid at the moment, and need to read more about it. Was long time I was studying this in school. So im not really remember it.

I really do appreciate your time and will read the link you posted for me.

Cheers.

Like I said, to better understand what you have, a somewhat detailed network topology diagram would probably be very useful. :)
