Title: Can't access OMV on network but can via Tailscale (SOLVED)
Post by: jphilebiz on July 06, 2025, 12:31:00 PM
Hi everybody,

Am stomped and baffled, I need a hand to fix what's happening here at the cottage. Am sensing an OPNsense issue/config item here.

Here is the summary of what led to this post:


How can I make it so my OMV is locally accessible? Any suggestions of where to look with OPNSense?

Thanks!!
***SOLVED*** My ADD brains inverted the 0 & 1 in the Tunables config. Sorry and thanks all.

  • Both networks (home (192.168.0.0 dhcp range) & cottage (192.168.1.0 dhcp range)) run OPNSense (latest)
  • The OMV was running on dhcp and changed it to static (192.168.0.51 - outisde of dhcp range) and well, no change
This IP seems to be in the wrong subnet.
?

Good catch, but that's a typo (fixed, thanks!)

Most probable reason for your issue is a wrong network configuration on either the server or the client. If all is set up correctly the OPNsense is not involved in the communication between them.

So configure both to pull the network settings from the DHCP to get sure.

Also ensure that the firewall on the OMV itself doesn't block access.

Do you see any related Firewall logs on OPNsense?

Are these two different locations? So how are they connected to each other, presumably over the internet? Is it a VPN ?

Using Tailscale on both ends, but should not matter? My laptop is also on Tailscale and can see local network.

Matters a lot actually, hence I asked. However I'm going to bow out, I'm not familiar with Tailscale.
I think it is based on wireguard, no ? Wireguard creates a separate network and there are firewall rules needed to get to local resources out of the endpoint network it is on.
