Redirect does happen, but no packets appear on guest interface: checked
by iptables rule for `NEW` on `tcpport 22` inside guest.
On host:
$ sudo lsof -itcp | grep 2851
packer24233 kit6u IPv4 1532725 0t0 TCP
localhost:52822->localhost:2851 (ESTABLISHED)

Doesn't work even with proper hostfwd
Doesn't work even with `-redir`
