Internet works on the lan side but not on the router itself.

Hi,

I have configured the internet on the mikrotik router. It works fine on the lan side, but there is no internet on the router itself (no ping to the internet ex. 8.8.8.8 ) . When I try to ping from terminal I get timeout. When I try to ping from winbox → tools → ping with specified src. address (10.1.7.1 - router’s local address) on advenced tab then it works. How can I fix it?

Configuration data from ISP:

Network: 172.16.1.10/30
Mask: 255.255.255.252
Gate ISP: 172.16.1.9
Addresses to use: 185.xxx.xxx.188-190

Not sure about network schema, bu try this:
Example:

/ip address
add address=172.16.1.10/30 comment=“ISP Private IP” interface=ether1 network=172.16.1.8

Solution 1 -

/ip firewall nat
add action=src-nat chain=srcnat comment=“NAT Private to Public” src-address=172.16.1.10 to-addresses=185.xxx.xxx.188

Solution 2 - Add the pubblic address to IP address on the ether1

/ip address
add address=185.xxx.xxx.188/30 comment=“ISP Public IP” interface=ether1 network=185.xxx.xxx.188

Thank you, first solution works!
