Hi Amin,

Leave the switch in Layer 2 mode

Cable VLAN2 to the to the outside router gateway 192.168.2.254 interface

cable VLAN3 to the to the outside router gateway 192.168.3.254 interface

Excuse the rough diagram

Make the port going to the outside router gateway, untagged in the vlans they will be transporting. (I am assuming that the router gateway is not vlan aware.)

IP hosts will most likely get DHCP from the router gateway. The IP hosts will then automatically send IP traffic to the router gateway.

VLAN 1 in my switch, could then be the only interface within the switch that has a IP address associated with it, for management purposes.

I can see from you post, that English is not your first language, if you want to speak to someone, you can ask a question by going to;
