My server has multiple interfaces, 1 is disconnected/not used (this is the one that comes with the motherboard), 1 is connected directly to another machine and 1 is connected to a router/Internet.
Currently I can access the TrueNAS dashboard using any of the two IPs (the server is directly connected to my desktop machine), what I can not do is using the two IPs to access the installed apps, they only work with the IP of the interface connected to the router/Internet, how can I make it so the apps listen on both IPs?
