This may be a very easy question, however I can’t for the life of me figure it out in my head…
We are about to have a VDSL line installed which is connected to a VDSL modem then presented on Ethernet. We will plug this in to our Mikrotik router and then authenticate with the ISP via PPPoE, they then assign a /29 to this VDSL interface.
How do I route these IP’s assigned to the VDSL interface to machines connected to the router, without NATing them? If we can somehow make these machines look like they are sitting on that external network and assign the IP addresses directly to the machines, that would be ideal.
I can’t be sure how they setup your specific VDSL circuit, but it would seem to me that in the Mikrotik when you configure the PPPOE client connection be sure click add default route and use peer dns and that will setup the routing automatically in the Mikrotik when the PPPOE client logs in to them.
From there I would think you could make a bridge and put however many ethernet ports you need in to it, assign one address in the /29 to the bridge, then plug your devices to those eth ports and manually assign them the addresses from your /29 using the IP address form the bridge as the gateway and turn on the DNS server in the Mikrotik to use the same bridge address for DNS on the machines as well.
