GS108Tv3 simple Vlan issues

[Babapou]

I would like to set up two vlan on my switch.

VLAN 2 "WAN" on port g1-3 in 192.168.1.0/24 (router is behind on 192.168.1.1)

VLAN 10 "LAN" on port 4-8 in 10.0.0.0/24 (router is behind in 10.0.0.1)

I do not want to do routing here. Only basic switch features.

My current switch conf :

VLAN 2 "WAN" on port g1-3

VLAN 1 "default" on port 4-8

I have this setup:

web hidePopup lanOnly,
ip address 192.168.1.100 mask 255.255.255.0
ip default-gateway 192.168.1.1
ip name-server 8.8.8.8

vlan 10

interface g5
interface g6
interface g7
interface g8

When I'm plugging my WAN cable in g1, and my computer on g2 or g3, I have no connection to router in 192.168.1.1 and DHCP is not working and doesn't give me @IP.

When I'm plugging my WAN cable in g4 and my computer on g5,g7,g8, I do have connection to router 192.168.1.1 and DHCP is working and do give me @IP.

Can you please explain me why ? I'm no going further as my VLAN "WAN" already doesn't work as I can't reach my router or get @IP.

Thanks

The original plan was VLAN 2 untagged for port 1..3, and VLAN 10 for port 4...10 isn't it? So configure it accordingly, possibly from the Web UI, and ensure no other ports are added unintentionally tagged (or untagged) to these VLANs.
