NAT'ing internal segment to Public IP

RouterOS General
1

Hi All,

How would i go about NATing traffic from one internal segment to a public IP, Below might help what im on about.

Internal
10.0.10.0
10.0.20.0
10.0.30.0

External
1.1.1.1
2.2.2.2
3.3.3.3

Now lets say 1.1.1.1 is my “Main” public IP but i have 2 and 3 to use. And at present all internal ranges NAT to 1.1.1.1 BUT i have now decied to make the subent 10.0.30.0 come from 3.3.3.3. I’m a little thrown on how to do this! ( probley something so simple )

Thanks,

Jack

Hello, you are right, it’s quite simple :slight_smile:

/ip firewall nat
add action=src-nat chain=srcnat comment=“NAT to 3.3.3.3” src-address=10.0.30.0/24 to-addresses=3.3.3.3

King Regards,
