The firewall allowed the TCP connection which needs to be established
for SSH to negotiate the authentication.

You know the IP address from the logs (85.92.138.150) which is likely
from some ISPs pool of addresses. You can always notify the ISP of the
attempted breakin and see if they have any information in their logs as
to who was using the address at the time of the breakin attempt. A
quick registry search via http://www.iana.org shows the 85/8 block was
assigned by RIPE. Doing a search at http://www.db.ripe.net on the
source IP adress shows the following:
