Hello Dexuan,
It seems, it is not completely correct, although the effect is as if it is not working.
Systat -ifstat 1 shows this:
[cid:image001.png at 01D1582C.39CF7E80]
So something is happening. But I can not reach anything. And the server can not be reached from the lan (hn0) or internet (hn1 and hn2).
I get a firewall message in /var/log/messages (first message from 11:18:55):
[cid:image002.png at 01D1582D.D4B9BD10]
But this is just caused by the problem?
If I can help with further information, please let me know.
Regarding Bug 187006, all interfaces have fixed addresses.
With kind regards,
Jac

Hi Jac,
BTW, what do you mean by saying "networking does not work anymore" -- can you please check if your issue is the same as
Bug 187006 - [hyper-v] dynamic address (dhcp) obtaining doesn't work on HYPER-V OS 2012 R2
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=187006 ?
Thanks,
