[Solved] Replacing Zyxel Router in Optical Orange Business Network: Possible or Not?

Hello
I have an optical fiber network with Orange installed in the Biznes with a fixed IP package.
Optical fiber to my router is connected via modem and Zyxel router that I have from Orange. Behind Zyxel is my router that distributes the Internet all over the company. Everything seems OK, but Zyxel likes to hang out. It happened to me in the last month twice. You have to turn it off and reconnect. Recently, it has hung in a strange way - DNSs have stopped working. The internet was supposed to be but it did not work DNS.
At home it's cool, I would reset myself, but in a company, however, I need stabilization and occasional resetting is not an option.
Can Zyxela be replaced with some kind of own equipment? At the Orange Business helpline from FTTH, I do not really know if I exchange Zyxela for other equipment or whether the service will work for me. Has anyone already done such a replacement?

No self-respecting supplier will allow an unauthorized device into its foreign network. You must report the problem to the supplier.

I do not really understand?
When I had vdsl from Orange, I did not use Funbox only from my own equipment.

These are two different VDSL and FTTH technologies. I did not hear anyone using Orange in this service from their device.

Just out of curiosity. What is this authorization based on ???

Unfortunately, I am not an employee of this operator so I do not know the details.

At the FTTH neostrada with funbox2, you can exchange it for your router that supports VLAN. I do not know the business option.

Such information should be available at the operator's BOK and here

You do not know the details, maybe an example of what you know. I am asking with spite, because somehow I can not imagine this "authorization".
What damage can the client router do to the operator's network?
IMHO more damage can be caused by the router to the user. Especially if it is misconfigured, has software errors or just hangs up, like in the subject.
Unky, can not you just connect the modem directly to your router?
Question what are the hardware (cable connection) and software configurations of both routers?
Maybe you have two DHCP servers on the network?

I have not tried but the whole configuration of the connection (eg access password) is set on Zyxel so it probably will not work.
My router has DHCP enabled. Zyxel from Orange operates in BRIDGE mode.

What is your "router" in your company?
This zyxel is VMG8324-B10A?
Do you have a login and password for the service?

Yes, this is the model.
My is the Fritzbox 3490.
I would have to look through the documents if there is a password.

You probably do not have login and password passwords and you will not get it from the operator because zyxel is set "top-down". Your fritz will not handle the WAN connection with VLANs.

You report the suspension of this Zyxel until someone fixes it. Maybe you only have a defective copy.

In business services, you will not exchange the device from the operator. However, you can connect your router to Zyxel and configure its WAN to a public IP address. Then you call Orange and ask for Zyxel to move into something like bridge mode. NAT, firewall will be turned off, only public address will be assigned to the LAN. Then Zyxel will be completely transparent for your router.

Yes, I have done it. Zyxel works in bridge mode. I have all IP addresses configured on my Fritzbox.

So, as I said, it remains reporting the operator's fault.

You can report the exchange of equipment to the operator, replace it with a new one / another free of charge.

The ZYXEL Router from Orange in the Fiber Optic Service in Biznes Pakiecie operates in Bridge mode due to the need to pass all ports. I have a connected 349 FritzBox from Zyxel, from which I distribute the internet inside the company.
Fritzbox has configured static IP assigned by Orange, assigned to Orange's DNS. Everything theoretically flutters as it should.
The problem arises in a situation in which I have to restart Zyxel. (Sometimes there are internet tags and the operator from Orange reboots Zyxel). After Zyxel restart, I can easily connect to the outside of servers in the company, but I have a problem to get out of the company. It looks like the DNS's did not work properly. After IP, I can easily connect to servers from outside, but when I connect to the address, for example "www.google.pl" I can not connect to the google website. I have two solutions for this: restarting my Fritzbox or disconnecting the LAN cable connecting the Fritzbox with Zyxel and reconnecting. From this moment, the network works fully as it should.

Summing up - Zyxel's restart works as Bridge, causing the Internet to not work properly without the need to restart the Fritzbox - DNS connections do not work
I replaced Fritzbox with another router, the situation is analogous. The problem is repeatedly reported to Orange, technicians claim that everything is OK on their side.
What else could you check to eliminate this problem?

The situation is uncomfortable for me. Sometimes the internet can hang on Zyxel. Then the phone to Orange - technicians reboot Zyxela and theoretically the internet works well from the point of view of the service provider, but from my side I have to restart Fritzbox. Of course, there is no problem as I am in the company but as I'm physically out of place and Zyxela need to be restarted until I appear in the company and physically do not restart my router, the internet does not work. Lime terrible.

Renewing an IP lease in FritzBox - I set 365 days for myself, but it can be 24 hours.
You can also think about the time switch in the company.

Thanks. However, these are half measures.
