I have a mikrotik 2.8 with two interfaces.

Interface1: 195.56.x.x/25
Interface2: 193.23.x.x/24

I have addresses behind the interface from 193.23.x.x/24 range

What routing should I set, to get it work. Now i use masquerading, but want to turn off, so the clients ip would be visible to the public net.

Thank you

Nothing special. Just be sure that your upstream provider is routing 193.23.x.x/24 block to your router.
