Need Help Accessing TrueNAS Share Across Different Subnets via Windows 10 Bridge

TrueNAS General
1

Hi all,

I’m trying to configure access to a TrueNAS share from a computer on a different subnet and could use some guidance.

My Setup:

  • Computer A: Windows 10 (IP range: 192.168.1.*)
  • Computer B: Windows 10 (Dual NICs - one connected to 192.168.1.*, one to 192.168.2.*)
  • Computer C: TrueNAS (IP range: 192.168.2.*)

Connectivity:

  • Computer A <---> 192.168.1.* Network <---> Computer B
  • Computer B <---> 192.168.2.* Network <---> Computer C
  • Computer B and C have direct internet access.
  • Computer A gets internet access via a simple proxy running on Computer B.

Goal:

I need Computer A to be able to access SMB/CIFS shares hosted on Computer C (TrueNAS). Access is only required within these internal networks; no external access is needed.

My Thoughts:

I was thinking a VPN server on TrueNAS (Computer C) might be the way to achieve this, allowing Computer A to connect via Computer B. However, I’m looking for the simplest reliable solution.

Question:

Is setting up a VPN on the TrueNAS box the best approach? Could someone provide setup instructions or suggest a potentially simpler alternative (perhaps involving routing configuration on Computer B)? I’m open to suggestions!

Thanks for any help!

What are the netmasks? What’s the gateway?
More generally, what’s the design goal for the network?

/24 subnet mask.
Computer B acts as proxy server for Computer A to get internet access but that is all.
I need access to TrueNAS(Computer C) on Computer A via Computer B.

I’m starting to think that routing on Computer B will be easier to setup.
