Changing internet VLAN after everything is set up
Hello,
I am in France and use a Deco M5 network in router mode so a double-NAT for now which has never caused any trouble until now but replacing my actual ISP router cannot be envisaged with this ISP.
I plan to switch to another ISP (Bouygues Telecom) where replacing the ISP router is easyer because requirements are using DHCP for IPv4, prefix delegation for IPv6 and, more importent for this topic, VLAN 100 for Internet.
I plan to firstly use again my Deco network behind the Bouygues Telecom box then atempt to replace the router if I can have an ONT from them as it has to be registered on their network to work.
The question is, how will I be able to change the VLAN without having to reset all my network? Because the Deco network won't be connected to Internet when changing settings and even if I change this setting withing being connected to my ISP router, it will have to reboot all the network and will I have to switch from the ISP router to the ONT durring network restart?
What process do you suggest me to follow? The cloud side of Deco makes me a little esitating.
