Centro Business 2.0, DMZ and LAN

Hello community

I have a Centro Business 2.0 (fw: 8.00.10) with several static IP addresses.

I now wanted to put a server in the DMZ (Settings -> Router -> Public DMZ) and mount additional storage from the LAN (via SSHFS).

So actually connect from the DMZ to the public router IP & forwarded port of the SSH server (Settings -> Network -> Port Forwarding).

But it seems that no connection to the LAN is possible from the DMZ (also makes sense because DMZ). But this should be possible via the public IP and the port forwards? It’s just that the port forwards don’t seem to work when you come out of the DMZ. I tried turning the firewall off and turning it on with the appropriate rule - without success.

Does anyone have an idea how this could be done/solved or is this strictly not possible?

Thanks in advance for your ideas.

Could it be that it is a Centro Business 2.0?

Because I know of a 2.0 version of the Centro Grande and an 8 FW…

The firmware of the Centro Business 2.0 is at an “older” level than that of the CB 1.0

The firewall there was extensively changed. As I understand it, it should also be possible with the Centro Business 2.0 with the new firmware.

Currently I don’t see any possibility. But I’ve never had this use case before.

What does the hotline say about this?
