Mapping a device between subnets

Post by kevinashaw »

I have a pair of subnets (both connected to a TS-453DU-RP QNAP server):
- Primary subnet: 10.0.0.0/24 (1GbE)
- Private subnet: 10.0.1.0/24 (10GbE)
That is the QNAP has two NICs, with one connected to the Primary subnet and the other connected to the Private subnet.
On the Private subnet is a Linux box (10.0.1.2) that needs to be accessible on the Primary subnet. For example, at 10.0.0.5.
Is there a way to map the Linux box out to the Primary subnet? The primary purpose is to `ssh` in to the Linux box from the Primary network.
I've been researching VLANs and Virtual Switches, but they don't seem to be right answer to this problem.
Thank you.

It's set on your switch.
If it is unmanageable switch then you are out of luck.

The networks does not share a switch, they share a QNAP. The QNAP has two NICs, one connected to each network. Since the QNAP is connected to each, it would make sense for it to handle mapping/connection between the networks. Am I looking at it incorrectly?
