In the "Edit IPSec Site-to-Site Connection Profile" on my cisco PIX I have the Basic Settings in the area "Protected Networks". Here I have to put the inside-network Adresses of Local- and Remote Network. Where can I find those settings in the configurations of my MikroTik?

My MikroTik Version RB450G

In mikrotik you add policy with source and destination networks under
"/ip ipsec policy" menu
