Hi MikroTik Support,

I tried to use CHR RouterOS v.7.10.1 Stable as shown in the attached picture and use the ether3 as Virtual Switch (Internal) in Hyper-v but by testing, it does not response ICMP echo requests (no ICMP reply packets back to DC1, PC1, PC2). However, I downloaded the CHR RouterOS v.6 (6.48.7 Long-term) and configured it as it is like before. I found it works well, i.e., it response ICMP echo requests and other traffic from other virtual machines. I would like to report this bug to the MikroTik support team.


Kind Regards
EkarinS.

I just tested 7.10.2 in HyperV and it does not find any connected virtual network adapter, with 6.49.7 it works fine.

Interestingly, I can even reproduce the problem when I upgrade from 6.49.7 to 7.10.2. After the upgrade all network interfaces are gone.

OK

thanks for reporting spam eliminated
