If this is a problem with the IB2, then another downstream router is unlikely to make a difference - especially if the IGMP proxy in your Netgear has worked so far (e.g. with the Internet Box Standard). IGMP proxy functionality is nothing new at all (although a few platforms have been late to properly implement the topic). Why should a new router bring a change?

If I saw it correctly, SWISSCOM still offers the Internet Box Standard today, e.g. if the shape of the IB2 doesn’t fit. I run an old router behind an IB standard. The DMZ in the IB makes no difference. Works perfectly.

I would first make sure that the IB2 is not the problem. You can also turn off the WiFi in the Netgear and put a modern access point behind it; it also supplies the missing LAN port on its switch.

I’ll avoid ASUS in the future. For me, their focus is too strong on WiFi optimizations. Even AsusWRT-Merlin can’t change that; At most, bugs are fixed there and additional features are offered.

And there’s too much movement in WiFI for me to combine it with a professionally configurable router today. It is better to divide both functions between different devices.

That’s why my approach is very clear for the time being: There is a router on or behind the uplink and behind it one or more access points that are tailored to the needs (transmission power, LAN ports) and can serve VLANs for the SSIDs and also on the LAN switch . Here too, AsusWRT (-Merlin) is too special for me and I rely on OpenWRT-capable devices.

If my IB or my router behind it no longer works properly, the two will be replaced by an ER-X SFP or similar.

Even if I hoped that the IB2 wasn’t the problem, I would take an ER-X and an OpenWRT-AP behind it. You can certainly enjoy a router for longer than these constantly changing WiFi standards. (Many of which don’t automatically bring much in practice anyway.)

“Connect directly” sounds to me like a LAN without an intermediate device.

But how do you get more than four devices (PS4, Xbox, USG, >= 1 TV boxes) connected to the four LAN ports of the IB2?

Is this really the setup?

My PS4 and Xbox are connected directly to the IB2 with the TV boxes, the USG from UBNT is also on the IB2 to which I do port forwarding. Behind the USG there are 2 PCs and my small ESXi LAB with 2 Trendmicro Serv

Thanks for the correction! Please excuse my mistake…

I have a setup here: FTTH <-> Internet box standard <-> third-party router (NAT, firewall, IGMP proxy) <-> VLAN <-> HD TV box.

When configuring the third-party router, I followed the following two articles:

SWISSCOM: Settings for third-party routers

TuxOne: pfSense 2.1 with Swisscom Access

TechIsland: Swisscom FTTH without internet box

Thanks to the third-party router’s IGMP proxy, Live IP TV ran, even without the IB’s DMZ.

Then I changed something and I can’t get it back to work. Neither with nor without DMZ. Unfortunately, I don’t see any signs in the third-party router’s log that any needed traffic is being blocked; neither from NAT nor from the Stateful Inspection of the FW.

Now there is the possibility that I did not reverse the configuration cleanly and simply cannot find the configuration error.

Or something has changed on SC’s part.

That’s why I’m first interested in whether everything still works as it should for other customers with third-party routers?

A third possibility: Because my firewall has to be set differently than in the linked articles, there may be a change somewhere that is only noticeable to me. Unfortunately, there is extremely little information about what data traffic really needs to be enabled. This can only be seen to a limited extent from the FW rules.

Turning off the FW doesn’t work because permission for the multicast addresses can only be granted there.

_The HD-TV-Box also has a Netflix app. I can’t say anything about their quality because I don’t use them. But I can’t imagine that it doesn’t work properly. Otherwise Netflix would quickly be in Swisscom’s doorstep.~

Mirroring from the Netflix-enabled device to the TV could also be an option.
