When you listen on a specific interface, Wireshark will
display all traffic for that interface (except you apply
a filter). So you're observing _two_ things at the same
time which probably aren't related: First is the web site
you're testing inside the LAN, second is an incomming SSH
connection attempt from exterior.

For testing your web site, temporarily add a filter for
the traffic in your LAN. Then, as a "second project", check
the SSH thing. It probably is just an automated search for
unsecured SSH accounts, performed by botnets.

That is quite possible. It could be a member of a mobile
botnet (which seem to become more common, even though the
preferred kind of botnet is still a fleet of office PCs
running "Windows").

No. Should I? ;-)
