Netflix has stopped working when devices are connected through switch
Hi, last week, after working fine for many months, Netflix stopped working on any devices that are connected to my cable modem via my Netgear GS108 unmanaged switch.
Netflix still works absolu...
Well, I fixed it.
The firewall settings had been changed on my Hyperoptic 'home gateway' (cable modem/router).

It's a ZTE ZXHN H298A V1.0 V1.0.25_HOP.1T3 supplied by https://www.hyperoptic.com
> "when these devices are connected" _to_ _what_ "through the Netgear GS108 switch"?
When my television, two disc players and a home cinema amp are all connected to the GS108 switch, which is in turn connected to a LAN port on the ZTE modem.
> then you can expect trouble if you connect multiple devices to it through a network switch....
Yeah, but everything worked fine for months until last week. :) (Which suggests either my ISP pushed out some firmware or config change, I guess, or Netflix changed something at their end...) On the admin dashboard page for the modem, I can see all four devices have been assigned a unique IPv4 address by DHCP.
> Swell. What _is_ "everything"?
42, of course.
But also: the ZTE modem, the Netgear GS108 switch, a NAS, my desktop PC, two mobile phones, a Kindle, a television, two BluRay players and a home cinema amp. All of which, when powered back up in a sensible order, appeared to obtain connectivity fine, except that Netflix wouldn't work on the ones going through the GS108 switch.
