Q: Internet sharing - internet doesn't work

Hello,

I have created an Internet sharing from USB Ethernet to Wifi on my MacBook Pro (2015). I am able to connect to the network with my iPhone, but i am unable to connect to the internet.


My network topology is Router (192.168.1.0/24) -> MacBook -> (192.168.2.0/24) iPhone.


Strange thing is, that i can connect to the router (which has IP 192.168.1.1). Therefore routing on MacBook works (i assume). But if i try to ping some external IP address, it stops on the router too.

 

More details:

Whole network is behind ISP's NAT.

The problem isn't wrong DNS for I have tried to ping IP address not a hostname.

If I open a webpage in Safari it says "Server is not responding".

I tried delete and readd all network interfaces.

This problem occured on El Capitan and now on Sierra.

 

I appreciate any advice. Thank you.

MacBook Pro with Retina display, macOS Sierra (10.12)
