GS108Tv3 simple Vlan issues

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

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
