Lo único que se me ocurre decirte es teoria , cada red es un mundo :
Como ya sabrás para comunicar vlan tienes que hacerlo a traves de un dispositivo de capa 3 o router, lo que se conoce como enrutamiento entre VLANs .A pesar de que las vlan se conecten al mismo switch , virtualmente son medios conmutados distintos. . Solo puedes comunicar tus vlan a traves de un router .Como tu switch parece ser que también trabaja en capa 3 o capa de red ( direcciones ip) , es decir lleva integrado un router , pues puedes aprovecharlo , no hace falta que el router resida fisicamente en el switch , podria ser otro..
¿ Como hacerlo ?. Desconozco el os de tu switch, si fuera Cisco te podria ayudar . Pero por lógica debes definir el mismo GateWay o puerta de enlace en cada estacion de cada vlan , el del router integrado en el switch , por ejemplo 196.0.0.15 .
¿ Y para salir a internet o enrutar a otro router ?
Defines una ruta por defecto en el router del switch que apunte al router fronterizo ( el que da salida a inet ) por ejemplo 196.0.0.1 . Con un router Cisco se haria :
Código:
router_del_Switch(config)# ip route 0.0.0.0 0.0.0.0 196.0.0.1
Espero te ayude .

If the devices placed in a VLAN need to communicate with devices in a
different VLAN, a router or Layer 3 switching device with connections to
both VLANs needs to be present. Your Switch will act as a Layer 3
switching device provided that it has an IP interface on each VLAN. See
Chapter 11 for information about IP routing.

Routing
To route network traffic using IP, you must perform these tasks in the
following order:
1 Configure VLANs.
2 Establish IP nterfaces on those VLANS.
Configuring IP VLANs If you want to use IP routing, you must first configure the VLAN to use IP.
You can create network-based VLANs that are grouped according to the
IP network address and mask.
See Chapter 8 for more information on VLANs.
Establishing IP
Interfaces
To establish an IP interface:
1 Determine your interface parameters.
2 Define the IP interfaces.
Interface Parameters
Each IP routing interface has these standard characteristics:
■ IP address — An address from the range of addresses that the
Internet Engineering Task Force (IETF) assigns to your organization.
This address is specific to your network and Switch. Refer to
Appendix C for details on IP Addressing.
■ Subnet mask — The 32-bit number that uses the same format and
representation as an IP address. The subnet mask determines which
bits in the IP address are interpreted as the network
number/subnetwork number and the host number. Each IP address bit
that corresponds to a 1 in the subnet mask is in the
network/subnetwork part of the address. Each IP address bit that
corresponds to a 0 is in the host part of the IP address.
■ State — The status of the IP interface. It indicates whether the
interface is available for communications (Up) or unavailable (Down).
This is not a user configurable parameter.
■ VLAN interface index — The number of the VLAN that is associated
with the IP interface. When the Switch prompts you for this option,
the menu identifies the available VLAN indexes.
Implementing IP Routing 89
Defining an IP Interface
After you decide the VLAN index, IP address, and subnet mask for each IP
interface you want to create, you can define each interface using the
Command Line Interface or the Web interface.
Before you assign IP addresses, map out the entire network and
subnetwork IP addressing scheme. Plan for future expansion of address
numbers as well.
Remember that you must define a VLAN before you define the IP
(routing) interface. See Chapter 8 for more information on VLANs.
