Problem with first RB450G

RouterOS Beginner Basics
1

Hi,

i’ve tried to configure my first RB450G as firewall.
I’ve set
LAN 192.168.88.1
WAN 91.81.145.142

My ISP router/gateway have IP address 91.81.145.141

It doesn’t work!!!

I followed the wiki step by step but there’s no way.
If i try to ping ISP gateway i have no answer;
I’ve configured my laptop with the same wan ip and gateway address: it works properly

Can anybody help?

What netmask did you set ?

On the MikroTik you need to specify 91.81.145.142/XX in the wan address.

You will also need to add a default route via the 91.81.145.141
