3 or more VLANs that connect to 2 servers using L2 switch

Wed Sep 14, 2011 10:40 am

Hi all,
I just learned the networking and mikrotik.
I need your suggestion and maybe some example.
I want to build 3 or more VLANs in my office and all the VLANs can access to Application Server and Internet GW server using 5 ports RB450G and layer 2 switches.
Could you please give me sugesstion about what step should I do ?
Thanks in advance.. :)

Why do you need or want to use VLANs? What kind of switches do you have? If they are unmanaged layer2 switches, they can't do anything with VLANs other than pass them on. Does your application server understand VLANs? If it doesn't then you will need multiple physical interfaces on it with managed switches to be able to really do anything with them.

Please give your specific goals of the setup and network layout in order to get specific answers and suggestions.

Maybe it will be clear if I attach this picture.
So I want to make 3 VLAN's. VLAN 10, 20, 30. And all of them only can connect to Application and proxy server and can't communicate with each VLAN.

:?

Sorry a little bit confusing about my explanation. .
I attached the picture.
What I am trying to do is to make 4 VLANs.
VLAN 10, VLAN 20 and VLAN 30 can't communicate with each other.
VLAN 40 can communicate with all of those three VLANs.
I have 2 Procurve 1810g-24 switched and 1 Mikrotik RB1100AHx2.

What should I do with the Switches ?
I can connect with same VLAN id with different switches with tagging for each VLAN.
I tried to connect them to Mikrotik with 1 trunking port for 3 VLANs but they can't communicate with the RB.

Should I connect each VLAN to each port of the Mikrotik and bridging them ?

Regards,

Djemmy

Hi did you solve your problem?

I had also trouble comunication with Trunk port on Linksys POE SRW208 switch.
But if I changed trunk port so it accepts multiple vlans (General Mode with Tagging enabled for VLANs 10,20,30,40.. all of your vlans defined on RB1100) then it would work.

Then all you need to do is make firewall rules on RB to drop packets/traffic to specific VLANS...

The switches should have a Trunk Port on each side (lets say 24) and I would enable STP to prevent Loops.
Other ports you can assign to whatever VLAN you wish

On RB1100 you create VLAN interface and disable Service-tag.. I spent quite some time because of this and my VLAN did not work..
