The Dude LAN Illegal Address Lists

I am new to the software and The Dude is causing my MikroTik Router to send a log to me every 5 minutes telling me the following:

Illegal Internal Activity on LAN.
More than 3 occurances of this event in 60 seconds!

firewall,info LAN: in:LAN out:LAN, src-mac 00:07:e9:d9:66:b8, proto TCP (SYN), 192.168.1.55:1710->66.138.14.202:8291, len 48

When i go into winbox to view the router setup, under IP Firewall Address Lists, it tells me there is LAN Illegal and gives 192.168.1.55 as the computer. I remove this from the Address List, but it keeps coming back. Can someone help me resolve. I do not know if i need to add a firewall rule allowing the above traffice or what. Please help. Thanks.

you have a firewall rule that puts this IP in your address list, and it seems that the firewall rule is not correctly configured. remove it.
