This is a short howto explaining how to set up a full-NAT on a Mikrotik RouterOS.

This setup allows you to hide (masquerade) your private IP address from a public network. This means, for example, that in your private network you can have whatever private IP you want which is then in turn translated to the public network IP given to you by your network provider. This tutorial can thus be used by clients who want to connect to a network without requiring a change to the internal IP addressing of their LAN.

Example

In the following example we have a wireless interface which connects to a public wireless network and an Ethernet interface for the local private network.

Suppose we have 192.168.1.2/24 (Internal Private Network)
Your RouterBoard's Ethernet interface is 192.168.1.1/24 (fixed Private Network IP)
Your RouterBoard's Wireless card is 10.140.1.30/26 (Public Network)
The Access Point you connect to is 10.140.1.1/26 (Public Network gateway)

  • First set the two IP addresses of the ethernet and wireless interfaces

  • Second set the static route so that we can access the external Public network

most likely you will want to use 0.0.0.0/0 as the destination in your primary public route—-Image:Mikrotik nat howto03.jpg

  • We start building the NAT as follows

  • First the Destination Network Address Translation setting (DST-NAT)

Only do this if you want to expose this specifice internal pc to all ports, this is the same as a DMZ—–Image:Mikrotik nat howto07.jpg

  • Then the Source Network Address Translation setting (SRC-NAT)

—On the Action Screen you could instead choose masquerade— Image:Mikrotik nat howto09.jpg

  • Private to Public Network Address Translation (NAT) is Complete!

hahahhah…….. pusing kan… lebih2 juga aku tapi setidaknya ada panduan lewat gambar hhhemmmmmm saya rasa mudah kok…. kalau berhasil nanti baru ku ganti dengan bahasa indonesia…
hehehehehee
