That’s correct. Ray-dude also initially didn’t see the help label as his Roon server was found (he told me in a PM to not clutter this thread). With routing (or layer 3 switching) the router forwards the traffic to the destiny VLAN so yes the router needs to know where it can find it. The router needs to become the default gateway for all hosts in your network and it itself needs a default gateway to the Internet/your Internet router. My Internet modem/router also needed a static route for the ‘music’ VLAN (pointing to the interface IP of the router in the music VLAN) as it itself is not a part of it.

@ray-dude, There’s a “help” text you can press on the Choose your Core screen and then the option for manually inputting the Core IP address becomes available. For isolation I’d go for the routed/VLAN approach. Port forwarding may perhaps work but is usually there for hosts you ‘hide’ behind NAT addresses so e.g. for forwarding traffic initially directed to a public Internet IP address+port to a private IP+port on your LAN. This is typically done by firewalls. Unfortunately I’m not familiar with the EdgeRouter and it’s really really hard to help remotely in these type of cases as I don’t know what your network looks like and there’s just too many dependencies plus stuff to configure. (I did not mention in my earlier post that you’d also need a DHCP server on each VLAN, a multihomed DHCP server/DHCP helpers in your router or work with static IP’s on each host.)

Roon works as long as endpoint(s) and server are in the same VLAN (or subnet in a non VLAN’ed network). Control devices can be in a different VLAN but one has to manually enter the server’s IP address once in the Roon app. I have it set up this way (using a modded Buffalo BS-GS2016 switch in L3 mode) and this works just fine as long as one creates the right routes everywhere they’re needed (all routers) so inter VLAN traffic is still possible and the Internet can be reached. This network segregation dramatically lowers the amount of multi- and broadcast traffic received by the devices on the separate VLAN. The bigger your network, the greater the reduction. Only after I set it up this way I remembered Apple Airplay relies on multicast protocols (mDNS etc.) as well so I now no longer can stream to my iPad (it’s in a different VLAN as are all other Wifi devices) from my Roon server. No biggie in my case but perhaps good to note here. But even if it wasn’t because of the protocols used by Apple Airplay, Roon still doesn’t allow it. Many have requested this limitation (=endpoints and server need to be in the same subnet/VLAN) be dealt with by Roon but AFAIK they have not yet indicated they will address this some day.

I think that’s because he linked to his post directly from the WBF forum.

Oops, I see I missed @austinpop’s post right above Nenon’s about the Buffalo switch. Thank you as well! I did not notice an increase in harshness deploying the Buffalo where I deployed it..but it replaced a cheap and internal SMPS powered D-Link switch in my case! 😉

I bought the Buffalo BS-GS2016 as well, in the third week of March. I’ve deployed it two weeks later as my upstream switch connecting to the downstream ER using fiber (25 meters since this equipment is in a different room). Apart from removing the SMPS and directly soldering a Ghent Gotham based DC lead to the board (a Keces P3 is now powering both the Buffalo and my Fritzbox DSL modem) I have not yet experimented further or made comparisons with the ER. Did want to say thank you to @seeteeyou , @Nenon , @RickyV and @romaz (over at WBF) for sharing what they shared about this switch. for those who have not seen it, Romaz shared his findings/comparisons here: https://www.whatsbestforum.com/threads/network-improvements-and-their-impact-on-sound-quality.30455/post-647211

The very long waiting times apply to Paul Hynes’ custom build service. This does not apply to products from here: https://www.paulhynesdesign.com The good people there can tell you the current waiting times.

You’re using single mode SFP’s so should use single mode fiber.

Just as an FYI, the 2018 LG OLED’s are 100Mbps max. for wired ethernet. Not sure if this is relevant though as the ER does auto negotiation. Also not sure if newer model years are 1Gbps yet.

Just as an FYI, there’s no longer an Elite or non-Elite version for the 2020 cable. Just an ‘unpowered’ (no 5Vbus wire internally) or the regular USB spec version (with 5Vbus connected). Also see: https://www.whatsbestforum.com/threads/sablon-usb-cable-2020-model.29912/

Hi Nenon, do you mean you got the Buffalo BS-GS2016/A (or the non /A version perhaps)?

12V has indeed been recommended before by John since a PSU then has to supply lower currents. All other things being equal this usually is more efficient (less cable losses, possible conversion to heat in a PSU when it can supply both higher and lower voltages). For the LPS 1.2 using 12V even is (near) mandatory when using multiple ports and/or the SFP slot since it can’t supply the required current at lower voltages (lower voltage=higher current to supply the same amount of power P=V*I).

Perhaps I’ve missed it; how do off topic “objectivist” posts get moved to this subforum? Do users have to report these posts?

Yes, that would the right place to insert the ER.

Ordered! 😁 Thanks for pointing it out, I had been on the lookout for a USB cable to replace the too short (20cm) Curious Regen link in my system and had started a list with several options to research including a second Phasure Lush^2, Shunyata Alpha USB, Intona (but not the $2000 or so Ultimate) and the Final Touch Audio Callisto but this one seems to fit the bill perfectly so I decided to take the gamble, end the search and order it. It’s shipping from London tomorrow. 👍
