Minimwatch subnet not found with VPN

[Fotospecht]

Hello,

sometimes I connect with my Mac via VPN to my NAS at home.

However I can't get Minimwatch to work on my Mac.
Even though I set the ohnet.subnet property to 192.168.1.0, Minimwatch reports that the subnet could not be found.
My local IP for the VPN adapter is 192.168.1.202 and I can also connect with the web browser to the Minimserver address http://192.168.1.100:9790.

I already disabled my Macs firewall but still no success.
Is there a way to further analyze this problem ?

Please open a Terminal window on the Mac, enter this command:

ifconfig

and post the full output here.

Thanks for the quick reply.

This tunnel:

utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
inet 192.168.1.202 --> 192.168.1.202 netmask 0xffffffff

seems to be pointing to itself. How did you set up the VPN at both ends?

What is the 192.168.2.1 address?

[Fotospecht]

The 192.168.2.1 is used by the Internet sharing service, where my Mac is configured as a local Wifi access point.

The VPN is a Cisco IPSec VPN. I've verified that the host is routing correctly over the VPN interface (which Mac OS/X calls "utun0"):

Code:

~$ scutil --nc list | grep Connected
* (Connected)      D7EB7C34-F481-436A-B259-7DB89602628B IPSec              "VPN (Cisco IPSec)"              [IPSec]

Please try using 192.168.1.202 for the ohnet.subnet property. Is this accepted as valid?

[Fotospecht]

It is accepted but the icon is still grey.

OK, this is progress.

The SSDP M-SEARCH request is probably arriving at the remote VPN server and being forwarded to MinimServer. If so, MinimServer will attempt to send a response to the sender's 192.168.1.202 address using a UDP packet. Are the routers at both the server end and client end set up to be able to handle this UDP packet and route it to your Mac? The UDP destination port number is allocated dynamically by MinimWatch when the M-SEARCH request is sent.
