My ADSL service provider assigned me a static public address and a block of 4 ip addresses. My MikroTik uses PPPoE client with an ADSL modem as bridge. So MikroTik get a public ip directly from my ISP.
Default public ip: 203.10.132.253
Additional ips:
203.10.17.24
203.10.17.25
203.10.17.26
203.10.17.27
Internal gateway: 10.1.1.1
Can anyone help me to configure my RouterOS so I can use the 4 ip addresses? I think I use only one IP address as a WAN IP.
What I want to do is assign 203.10.17.x addresses to servers behind the router. So each server will have a public ip address. I have two servers. I am happy if even I can just use one of 203.10.17.x addresses.
Just give your servers 203.10.17.x IP and make their gateways and DNS the same one you obtained from your ISP. Bridge your ether1 interface to your PPPOE dynamic interface and connect your servers to the ether1 interface. And See if that works..
I’m afraid this won’t work.
From zhex900’s statement I rather see his provider has assigned a block of IP addresses and a transport network (with 203.10.132.253 as "default IP - this could be his IP or the peer IP in a/30 network).
Additionally, the fewest DSL providers would enable BCP for clients being able to bridge PPP-clients.
I’d set up a bridge with one of the IP addresses and let the router do the job.
Either each server gets a real public address (which brings some demands in decent firewalling) with the bridge interface as a gateway or I’d assign all addresses to the bridge and use port forwards into his 10.1.1.0/24 LAN. For outgoing communication from the servers to WAN there’s the need for some src- and dst-nat rules as well for marking connections and routing-marks.

Are you sure you typed the addresses correctly?
A /29 network with these addresses should have six usable addresses instead of four - and 203.10.17.24 would be a network address - the first usable should be 203.10.17.25…
