Need help with IP subnet RB433AH

RouterOS Beginner Basics

Now i have 5 ip adreses, Ether1 uses one of them, how to translate another 4 IP adreses into interface Ether2 and Ether3

Network 10.10.10.176/29

Ether1 is 10.10.10.178/29

I need to translate other IP adreses into Ether2 and Ether3

Ether2 will be 10.10.10.179-180

Ether3 will be 10.10.10.181-182

:frowning:

:smiley: duhh.. Use subnet calculator i u don’t know how to calculate them. subnet calculator

Maybe you have some examples, what for I need a subnet calculator ? I only need to use another IP’s on another interfaces thrue Ether1.

Can you tell more clearly what u are up to? U wanna set Ether1 ip range 10.10.10.178/29 (10.10.10.177 - 10.10.10.182)? and split it between ether2 and ether3? :smiley:

I am guessing that the router that is upstream from your router has 10.10.10.177 with a /29 netmask assigned (you were given a “gateway” of 10.10.10.177). If that is the case, you cannot assign the other IPs on different interfaces. You can’t have the same subnet on multiple interfaces and the upstream router will need to know how to route to you. NOW, if you want to destination nat the 179 IP to some device that exists on your ether2 interface (with a different IP range), you can do that. Is that what you mean?

I understand this:

Thanks for the answer, NAT is not just right thing I need :frowning: I’ll try obtain this gateway to my interface from ISP.

Ether 1 is for connecting with upstream, and take those adreses.

Ether 2 and Ether 3 is for the other addresses 10.10.10.177 - 10.10.10.182, The best way I thing is to put Ether 1 as the 10.10.10.177 for this subnet, and then I can take other IP’s to Ether 2 and Ether 3 with calculator :smiley:

May-be I can split them, but will have only 1 working address in new range :slight_smile:
