Universal Media Server | Forum

Hello,
I would like to access my UMS server from wifi, which runs on a different network via my router. The goal is to make my music available to my iPhone

UMS server 10.0.0.0/8.
Wi-Fi is 10.1.0.0/8
Router is running Alpine Linux 3.17.1 with Shorewall
Router has 3 NICs, for 3 distinct, physical networks: LAN, WAN and Wi-Fi.

Is it at all possible for uPNP to work through my firewall?

If all fails, I could look into getting a second NIC for the server and multihoming it.

In theory as long as UMS is on the same subnet used by your iPhone.

I know little about networking though so can't be much help with this. All I know is if you have multiple routers you need to have DHCP turned off on all but one.
I suspect you have vastly greater knowledge about networking than me with this setup.

As for firewall you should have ports 9001, 9002, and 5001 accessible (with default settings), UPnP should work as it is all inside the network.

Unless I'm mistaken, UPnP also does some broadcast shenanigans for service discovery.
