Powerconnect 6224 can't access the internet

Hello there 

please i need your help . 

i configured my Vlan 2,3 and 199 on my single switch 6224 

Vlan2 for corporation 192.168.2.254

Vlan3 for guest  192.168.3.254

Vlan199 is where my internet and my gateway for it is 192.168.1.199

all what i want is very simple i need an assitant how i can get a computer connected to Vlan 2 and Vlan 3 to talk to the internet. 

NB: the machine for testing that i connect to vlan 2 port 3 has the ip address 192.168.2.10 gateway 192.168.2.254 and my DNS is Public.

from inside the CLI  i can ping 192.168.199.1 after i added on this device a static route to redirect back. 

still can't access the internet. 

please find bellow my configuration
