The problem is the users from the LAN cannot get access to internet. Anyone have the same problem can help me with this senario.

Your adressing is wrong, but we need more info about the netmask.
All interfaces on a router must be on different networks, as I read it you have 172.30.112.# on all interfaces. Even if you subnetted it the adressing is still wrong as you have on RED and on GREEN.

ORANGE (if exists)
