VLAN Mikrotik Basado en Puertos

VLANs Mikrotik - Basada en Puertos. Tenemos dos routers Mikrotik (RouterOS).

Internet

El router Mikrotik esta conectado desde el puerto ehter1 (WAN_ether1) a uno de los puertos ethernet del router ISP, usando DHCP Client. 

[admin@R1] /ip dhcp-client> print
Flags: X - disabled, I - invalid, D - dynamic 
 #   INTERFACE    USE-PEER-DNS ADD-DEFAULT-ROUTE STATUS      ADDRESS           
 0   ether1        yes          yes               bound       192.168.88.12/24

Todos los puertos de un switch por defecto pertenecen a la la vlan 1. El switch necesita de un router para mover (forwarding) el tráfico entre las vlan. Eso permite la comunicacion entre diferentes VLAN.

Las VLAN ID solo aparecen en Switch administrables y funcionan en capa 2. La segmentación se produce en el Switch.

El Switch tiene una base de datos llamada tabla CAM donde realiza un seguimiento de cada computadora conectada: 

- MAC Address
- Numero de Puerto
- VLAN ID - Solo en Switches Administrables

Las VLANs se utilizan se utilizan para segmentar una red, lo que permite mejorar la seguridad, el rendimiento y la gestion de la red. Los dispositivos de una VLAN pueden ser configurados y administrados de forma separada.

Los dispositivos CRS (tienen capacidad de capa 3) se pueden utilizar como enrutador y conmutador al mismo tiempo, útil para redes que se centran en el rendimiento de la red interna.

VLAN - Laboratorio de pruebas

Ambos routers estan en blanco - System - Reset Configuration - No Default Configuration - Reset Configuration.

Tenemos un router 1 (R1) donde se crean las VLAN, vlan10 con vlan-id=10 y vlan20 con vlan-id=20 en la interfaz Ether3, cada una con su direccionamineto IP y un DHCP Server. Esas VLAN se envían Tagged (Trunk en Cisco) a través de Ether3 y se reciben Tagged en el router 2 (R2) en el puerto Ether1. Luego se entregan como Untagged (Access Port) en los puertos Ether3 y Ether4.

Configuración vía comandos del Router 1.

Nota: La dirección IP del dns-server correspnde al servidor DNS de mi red interna. Puede utilizar DNS públicos si no tiene un servidor DNS local, por ejemplo, 1.1.1.1 o los del propio router Mikrotik, por defecto 192.168.88.1. 

/interface
add interface=ether2 name=vlan10 vlan-id=10
add interface=ether2 name=vlan20 vlan-id=20
/ip pool
add name=dhcp_pool0 ranges=10.10.10.200-10.10.10.254
add name=dhcp_pool1 ranges=172.24.1.200-172.24.1.254
/ip dhcp-server
add address-pool=dhcp_pool0 disable=no interface=vlan10 name=dhcp1
add address-pool=dhcp_pool1 disable=no interface=vlan20 name=dhcp2
/ip address
add address=10.10.10.1/24 interface=vlan10 network=10.10.10.0
add address=172.24.1.1/24 interface=vlan20 network=172.24.1.0
/ip dhcp-server network
add address=10.10.10.0/24 dns-server=192.168.88.200 gateway=10.10.10.1
add address=172.24.1.0/24 dns-server=192.168.88.200 gateway=172.24.1.1

En el Router R2 se crean las VLAN en el puerto Ether1 que es donde recibimos las VLAN con el nombre y vlan-id correspondiente, vlan10 vlan-id=10 y vlan20 vlan-id=20. Teniendo en cuenta que para que las VLAN se comuniquen entre dispositivos el id debe ser el mismo. Tambien hay que crear un bridge por cada VLAN Bridge_VLAN10 y Bridge_VLAN20. En la pestaña Bridge - Bridge - Ports, agregar dos interfaces: la propia VLAN y el puerto físico donde quiero entregarla como acceso (Access Port). En el caso de la VLAN vlan10 los puertos son: la propia VLAN vlan10 y el puerto Ether3. En la VLAN vlan20 los puertos son: la propia VLAN vlan20 y el puerto Ether4. Evidentemente, si quiero entregar la misma VLAN en más puertos este último paso se repite para todos los puertos involucrados.

Configuracion vía comandos Router 2 (R2) 

/interface vlan
add interface=ether1 name=vlan10 vlan-id=10
add interface=ether1 name=vlan20 vlan-id=20
/interface bridge
add name=Bridge_VLAN10
add name=Bridge_VLAN20
/interface Bridge port
add bridge=Bridge_VLAN10 interface=vlan10
add bridge=Bridge_VLAN10 interface=ether3
add bridge=Bridge_VLAN20 interface=vlan20
add bridge=Bridge_VLAN20 interface=ether4

Conecto un PC a Ether3 del router R2 y recibe una IP del DHCP-Server configurado en R1

(Opcional) -¿Cómo Permitir tráfico de VLANs? 

/ip firewall filter
add chain=forward src-address=10.10.10.0/24 dst-address=172.24.1.0/24 \
connection-state=new,established action=accept comment="Permitir VLAN10 \
a VLAN20"

/ip firewall filter
add chain=forward src-address=172.24.1.0/24 dst-address=10.10.10.0/24 \
connection-state=new,established action=accept comment="Permitir VLAN20 \
a VLAN10"

Ubicación de las reglas: 

Antes de cualquier regla que bloquee tráfico (ej. action=drop).
Usa el menú Drag & Drop en Winbox para ordenarlas.

Explicacion: 

Las opciones connection-state=new,established permiten:
new: Conexiones iniciadas desde el origen.
established: Respuestas al tráfico iniciado.

Permitir acceso administrativo sólo desde la red 10.10.10.1/24 

add chain=input src-address=10.10.10.1/24 protocol=tcp dst-port=22,8291,8728,8729 \
action=accept comment="Acceso administrativo (Winbox/SSH/API)"

FreeBSD vm-bhyve X11 Forwarding usando SSH

Ejecutar aplicaciones X11 desde invitado vm-bhyve en host.

La(s) aplicacion(es) se ejecutan en la máquina virtual invitada, sin embargo, se muestra en el host. La importancia de esto radica en que puede ejecutar una aplicación en una lugar y mostrar la ventana en el host.

Si una aplicación no es soportada en la máquina host pero bien soportada en la vm podrá ejecutarse en una ventana del host.

Ejecutar Firefox en una vm y mostrarlo en el host FreeBSD 13.0
basado en el reenvío X11 usando ssh.

Configurar y permitir el enrutamiento inter-VLAN Cisco EVE-NG

En computación, un Router on A Stick (ROAS), es un router que tiene una sola conexión física o lógica a una red. Es un método de ruteo inter-VLAN (redes de área local virtual) donde un router está conectado a un Switch vía un solo cable. El router tiene conexiones físicas a los dominios de broadcast donde uno o más VLAN requieren de enrutamiento entre ellos.



Configurar Sw1 y Sw2 como switches VTP transparentes:

Sw1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Sw1(config)#vtp mode Transparent
Setting device to VTP TRANSPARENT mode.
Sw1(config)#vtp domain CISCO
Changing VTP domain name from NULL to CISCO
Sw1(config)#vtp password cisco-vtp
Setting device VLAN database password to cisco-vtp
Sw1(config)#do sh vtp status
VTP Version                     : 2
Configuration Revision          : 0
Maximum VLANs supported locally : 36
Number of existing VLANs        : 5
VTP Operating Mode              : Transparent
