Connect from one LAN to another LAN

NutritioN · 12 Feb 2015 at 14:33

Hi, this should be simple...

I've never worked out if it's possible to connect to a device on a different LAN that has a wired link somewhere.

There's a switch connecting a NAS(192.168.3.xxx), LAN1(192.168.3.xxx) and LAN2 (192.168.0.xxx)

I want a machine on 192.168.0.xxx to connect to the NAS, is there a simple shortcut route I can configure? The LANs are segregated for a reason so I'd rather not change the current setup.

Is this possible?

Cheers.

We need a bit more info. Are they in the same building or separate sites?

If they're in the same building they should, in theory be configured to see each other, unless a) the person setting it up doesn't know what they're doing or b) they're not supposed to see each other.

Small building, over two floors. Consumer grade hardware, consumer grade IT manager (me). I control it all, LAN2 and LAN1 are on different floors.

You could achieve this with VLANs

Edit, or get a NAS with 2x network cards. (far less work for you to do), DS414

Well, given that you want to route from 1 subnet to another, this is the sort of thing a router handles.

Setup a firewall rule to deny traffic across subnets except to the NAS and you're good to go.

The device I want to see the NAS from is connected to a DLink DIR-655. The DLINK itself has an IP of 192.168.3.xxx given to it by LAN1, but hands out an IP via DHCP (LAN2) to the device on 192.168.0.xxx .

I tried to set up the DLINK in bridge mode to use the DHCP server of LAN1 but apparently this is not possible in the latest firmware. Without looking right now, I don't think a VLAN is possible with this hardware.
