Can't ping to public except own public IP

RouterOS Beginner Basics
1

Hi from newbie,

I have configured two interfaces. ether1 for public ip, ether2 for internal network and for dhcp.
The problem is that when I connect my notebook to ether2, I get IP from DHCPd, but I can ping just local network and ether1 public IP, but I cannot ping anything else. If I ping from mikrotik router while connected to ssh, everything works just fine, I can ping all addresses.

IP addresses:

 #   ADDRESS            NETWORK         BROADCAST       INTERFACE                                                                                                  
 0   PUBLIC_IP/24   PUBLIC_IP.0         PUBLIC_IP.255  ether1                                                                                                     
 1   192.168.60.1/24    192.168.60.0    192.168.60.255  ether2

Route list:

#      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0 A S  0.0.0.0/0                         PUBLIC_IP_GATEWAY_IP re... 1       
 1 ADC  PUBLIC_IP.0/24    PUBLIC_IP      ether1             0       
 2   S     PUBLIC_IP.0/24    PUBLIC_IP      PUBLIC_IP_GATEWAY re... 1       
 3 ADC  192.168.60.0/24    192.168.60.1    ether2             0       
 4   S  192.168.60.0/24    192.168.60.1    ether1 reachable   1

I think there’s missing some nat rule? In BSD like systems with pf it would look like:
nat on $ether1 from $ether2:network to any → $ether1_IP

How it would look like in routeros?
I have tried something like this:

/ip firewall nat> add chain=dstnat dst-address=PUBLIC_IP action=dst-nat to-addresses=192.168.60.1
/ip firewall nat> add chain=srcnat src-address=192.168.60.1 action=src-nat to-addresses=PUBLIC_IP

But it didn’t help to me. How can I solve this problem?

/ip firewall nat
add action=masquerade chain=srcnat comment="" disabled=no out-interface=ether1 src-address=192.168.60.0/24
/ip route remove 4

Thanks for your help, it solved the problem.
