Hi,
I ran a ping from our mikrotik server to 66.175.96.7, and we’ve -200% packet loss, only 27 packets sent and 81 received…Any idea what could be causing this?
Or maybe not? Here is a Windows box ping to the same ip

You are simply receiving duplicate ICMP responces.
This can happen if the IP really is terminated on 3 devices, and all 3 respond to ping requests on that IP.
Since we dont know how the owner of the IP address distributes it internally, and has his equipment configured, this is completly normal.
Hi, I have the same problem. I have perfectly established a connection via sstp between two mikrotik of which one is virtualized. however when trying a ping to google dns, I get negative packet losses.
What could be causing this?
