Simple Routing help

Lab:

Using a 4g/3g modem/router.

A 8 port L3 switch.

A wireless controller capable of NAT.

A wireless Access point.

... .

I always face this dead end when i create a lab and i need someone to explain what i am missing, its straight forward but I'm a routing noob ..

Clients on my second vlan can't reach or ping my internet gateway.

I configure everything on a flat vlan1, then add another vlan 10.

All devices on vlan 1 can reach the internet, but not vlan 10.

-------------.

Switch:

-------------.

Vlan 1 Ip 192.168.8.10 DHCP scope Default router 192.168.8.1

Vlan 10 Ip 10.10.10.10 Scope is on the wireless controller (it wont provide IPs if the scope is on the switch.. not sure why)

ENABLED IP ROUTING.

‐--------------------.

Wireless controller.

‐--------------------.

Default gateway 192.168.8.1

Vlan 1 .

Ip 192.168.8.102 .

Vlan 10 . Ip 10.10.10.102 . DHCP scope. Default router (not sure i tried 10.10.10.10 to point to the switch interface and 192.168.8.1) non worked

-----------------.

3g router .

-----------------.

IP 192.168.8.1

I tried to NAT vlan 10 on the controller to make it talk to vlan1 but didnt work.
