Is the service name FTP or another one? I tried FTP but ARC still won’t work.
Can you explain how I’d manually open the port in my router’s port forwarding configuration?
External and internal ports are both listed as 20-21
Listening port in Roon is 55002 (port)
Roon core ip is 192.169.1.12 the same as the internal IP address for the FTP service
Modem / router Netgear Nighthawk RAX120 - TP-Link 8 PORT ethernet switch TL-SG1008D
I’m in Australia & my provider is Exetel - Ethernet to Nucleus+ - not in Bridge mode, I’m unsure of the correct port forwarding settings
Well-known standard protocols like FTP or HTTPS have fixed port numbers below 1000 and most routers provide predefined rules for that, so if you choose FTP it will autoconfigure the rule with the standard port for FTP, which is 20/21, like this:
However, apart from that the FTP label is just a name for the rule that doesn’t really matter. It’s the port number that is important. So if you create a rule from the predefined list that is called FTP, and then change the port number to Roon’s 55002, then it will use that.
ARC will send its traffic to port 55002 and your router needs to know what to do with traffic coming in on that port, i.e. forward it to the Roon Core.
That said, most routers provide a “custom” rule option where you can choose a port number and apply any name label you want, like “Roon ARC” or whatever, so in this case it’s better to do it like this just for clarity.
Your router’s manual normally has a section devoted to this. Or try this:
