ssh attempts on non-ssh port

I am seeing Fail2Ban blocks for ssh connection attempts on a ports that I don't have configured to allow ssh connections from.

Is this just seeing the attempts even though there is no way to actually use those ports?

Example:

Mar 28 23:18:30 ulterius sshd[18292]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=23.228.245.151  user=root
Mar 28 23:18:31 ulterius sshd[18292]: Failed password for root from 23.228.245.151 port 3355 ssh2
Mar 28 23:18:33 ulterius sshd[18292]: Failed password for root from 23.228.245.151 port 3355 ssh2
Mar 28 23:18:35 ulterius sshd[18292]: Failed password for root from 23.228.245.151 port 3355 ssh2
Mar 28 23:18:37 ulterius sshd[18292]: Failed password for root from 23.228.245.151 port 3355 ssh2
Mar 28 23:18:39 ulterius sshd[18292]: Failed password for root from 23.228.245.151 port 3355 ssh2

IPtables are not setup to allow a connection to SSH on port 3355. So any attempt would be denied. but the first line seems to have me wondering if it is still getting though?

#  Allow SSH connections
#  The -dport number should be the same port number you set in sshd_config
-A INPUT -p tcp -m state --state NEW --dport 2222 -j ACCEPT

is the section in my IPtables related to ssh.
