The firewall (Sonicwall TZ170) is logging the following
Possible port scan dropped 220.127.116.11, 12200, WAN xx.xx.xx.xx, 8081, WAN TCP scanned port list, 8080, 80, 1080, 8800, 8118

Note: I replaced our wan ip with XX.xx.xx.xx and attached the scrren shots for your review.
In addition I am using non standard login name and strong password and add my IP to be able to connect from remote location to the firewall only. anything else I should be concerned?
