Peer static routing

RouterOS Beginner Basics
1

Hello,

I have the following situation.

My ISP is giving me a block 2.2.2.112/28 static IP addresses.

In order to use those IPs the gave me one IP that acts as a peer 1.1.1.70/30.

My question would be how can I configure MT so that through this one IP I use the other IPs.

They gave me the following script that applies on Cisco routers if it can help:

interface fast 0/8
description LINK to ISP
ip address 1.1.1.70 255.255.255.252
!
!
interface fast 0/1
description LINK to PC's
ip address 2.2.2.113 255.255.255.240
!
!
!
ip route 0.0.0.0 0.0.0.0 1.1.1.69 name default_gw

All help is appreciated

1.1.1.70 is your address on the link /30 network. To use your /28 you simply send traffic with a source IP from the /28 range to the gateway on the link network (.69 in your example). The ISP will route reply traffic for the /28 addresses via your address on the link network (.70 in your example).

If you want to test before you have clients using the /28 numbers then once you have the link net working and can ping the ISP gateway try the following:

Create a bridge on Mikrotik.
Assign on of your /28 IPs (not the lowest or highest number) to the bridge.
In Tools ping the ISP gateway and set the source address to the /28 number that you assigned to the bridge.
Check that you see ping replies.
