I tried connecting a Zyxel GM4100-B0 instead of my Internet Box 2 in order to have more control over my network (I use another router). The g.fast connection works right away, the IP is assigned but there is no Internet connection. I then managed to add the DHCP Option 60 on my router and was able to insert my Swisscom credentials in the captive portal. At that stage Internet works but after a short while a splash page from Swisscom asks me the activation code and I have no Internet access. Does anybody have any experience with such a setup? I understand that I should also define VLAN 10 but I did not try it yet. Thanks!

I can confirm that adding VLAN 11 it works perfectly fine.

Hello. I'm trying to operate a Zyxel GM4100 which is to be connected to a Fritzbox. Which settings helped you? I can't get any further in Zyxel than the activation screen.

Bear in mind that it does not create a NAT (it is a bridge) but If you connect directly and type its IP Address in a web browser you should access the GUI. The credentials are on the back of the unit and the IP likely 192.168.8.1 (google it as I do not remember).

Hear are the instructions: [https://www.swisscom.ch/en/residential/help/device/internet/external-router.html](https://www.swisscom.ch/en/residential/help/device/internet/external-router.html) For DSL you don't need to set VLAN 10.

I'm not sure how and why it works, but it's not because you set VLAN 11. Where did you find this information?

I can confirm that without VLAN 11, at the time I configured my device, it did not work. I found the information in a post on a Swisscom forum. I cannot tell if it is still required.

@"maotter"#p817828 I'm trying to connect my GM4100-B0, but unlike in your case, I don't get anywhere. I'm using traditional line (no fiber), hence as described by Swisscom support page [Fremdrouter an Swisscom Netzwerk anschliessen – Hilfe | Swisscom](https://www.swisscom.ch/de/privatkunden/hilfe/geraet/internet/fremdrouter.html?srsltid=AfmBOoqrqLPZol0LCirFFMgszpe_vd2fDO_SH2GI1zOlkpLUhuF1ID4W#acc-bOyTxQ%5Bselected%5D%5B%5D=0), I'm not required to configure VLAN 10, only DHCP Option 60 with vender ID details **100008,0001**. Unfortunately, nothing happens. I won't get any internet connection and no login page either. I configured encapsulation IPoE and use IPv4 IPv6 DualStack, MTU is set to 1500. Interestingly enough though, as per WAN Information provided by the router, I receive an extern IP, IP Subnet and DNS servers 195.186.1.162 / 195.186.4.162, but my system claims to not be able to reach the DNS servers. I'd really appreciate some support how to correctly configure the GM4100-B0. mySwisscom support unfortunately turned me down as there's no support if third party devices are used. Many thanks for your help. Much appreciated.

@"Mike-S"#p877940 Schon mal mit DHCP auf der WAN-Schnittstelle des Routers probiert? Ist nämlich die einzige Verbindungsart welche Swisscom bei Privatkundenabos anbietet

@"Mike-S"#p877940 Und Funktioniert denn ein Router der Swisscom an diesem Anschluss? Wenn ja erst dann kann man mit Fremdrouter probieren. Und wenn du zu viele Versuche machst, wird der Port gesperrt, und dann bleibt er eine gewisse Zeit gesperrt bis man erneut probieren kann. Du musst am Anfang die DNS der Swisscom benützen nur so kommst du auf die Anmelde-Seite. Evt deinem Laptop Manuell die DNS verpassen. Gruss Lorenz

@"Werner"#p877943 Danke, Werner. Ich hab DHCP auf der WAN konfiguriert, leider ohne Erfolg. Nachdem mich der Swisscom-Support abblitzen liess, hab ich bei Zyxel direkt einen Support-Fall eröffnen wollen und - ratet mal - Zyxel bietet keinen Support für den GM4100, weil dies gem. der Seriennummer des Gerätes von meinem ISP erworben wurde und ich sollte mich an meinen ISP für den Support wenden. Und so schliesst sich der Kreis.
