Some sort of Passthrough available ?

RouterOS Beginner Basics
1

I am looking to buy myself a new router and RouterOS has gotten my attention.
But before I am going to buy one I want to know if RouterOS can do the thing I want it to do.

First the setup:
I have an internal network with 5 devices and 3 Digital TV boxes from my ISP. There is a combination of wired and wireless connectivity via an AP of DLink.
The modem that I currently have provides 5 internal IP’s in the 192.168.0.x range to my personal devices and it provides 3 external IP’s in the 10.0.0.x range to the settop boxes (that is needed for the interactive possibilities of the STB’s).
In the modem/router combination that my ISP has given me, there is some sort of passthrough available for the STB mac ID’s.

My problem:
Is there a way to configer RouterOS to give interal IP’s to all the devices except for the 3 MAC ID’s of the STB’s ?
They should still get an external IP from my ISP.
Can this be done with VLAN’s or some sort of bridge ?

I’m not really a network expert so I don’t know the exact term that is used to achieve this.

If anyone can help me with this, that would be great :slight_smile:

Its possible.

I think what you want is a bridge with 2 gateway IP.

A dhcp server at the interface (bridge) and the possibility to set permanent ip to some devices.

Its possible to do with vlan, but why stuggle with vlan’s? :stuck_out_tongue:

And… routeros. is capable of almost whatever you want. :slight_smile:

Thanks for the answer.

So it is possible to do this. Now I only need a crash course in networking and I’ll be able to program the OS to do it for me.

But you suggest to do this with a bridge ?

In short the thing I need is the following:

3 devices need an external IP from my ISP (based on a list of MAC addresses) and all the rest needs to get an IP from my router. The router itself also needs to get an IP from my ISP.
All the devices need to be connected to the router to avoid having to create a double cabled network in my house.

then bridge your wan and lan. set IP from provider to bridge.

Its possible to have a local IP to the bridge, and have a dhcp server here to provide to more units. But, I don’t know how this will impact your isp. Its better to use 2 port for “lan”. 1 port for dhcp clients and one port for static ip. If this is not possible, then use vlan.
