Change NAT

RouterOS Beginner Basics
1

Hello,
my network topology looks like this: ISP-RouterA-routerB-Sector Antennas. On both routers I use NAT. The ISP has given me 1 global IP address. But as the number of my custommers on sectors have grown, I asked the ISP to give me more IP adddresses and they agreed.
I plan to remove NAT on router B to allow each sector custommers use one global IP. But I am not sure how to do this. Can you please suggest me something?

You have 3 methods to choose from… I suggest you use which ever you are most comfortable with.

  1. PPPoE

  2. DHCP
    This is what you do now except with public addresses NO NAT, NO Masquerade.
  3. 1 to 1 NAT
    http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/NAT (1 to 1 Nat at the bottom of the page)

If you would like to choose a method then ask for an explanation it would be easier than explaining them all.

Thanks,
I think I will use 1 to 1 NAT as I am more familiar with it.
