Multiple network interfaces: telling OH2 the one to use

as disussed here:

I think, this parameter is just to set the subnet (not a IP-address). What I’d like to do, is to tell openHAB to use a NIC (instead of a subnet) - I know, the IP-address and subnet of the OH-Server should be either static or “static DHCP lease”. But this parameter doesn’t seem to address this.

besides, my assumptions are:

  • the “primary NIC” will that one, which traffice openHAB uses
  • if there are multiple NICs, all others will be “ignored”

This behaviour seems to be the case, as I recently tested my remote Pi in my home network with both eth0 and wlan0 activated - wlan0 got all the traffic and eth0 traffic was ignored.

My second bet would be, this is ESH-related - not OH-core?
