Weird LAN access in my Router Logs

Hi there.  Any network gurus out there that can help me with a query?
My NETGEAR WNR1000v3 is configured to mail me it's router logs every so often.  Today I found stacks of entries like this:
[LAN access from remote] from 82.165.202.169:20 to 192.168.1.10:51368 Thursday, Feb 05,2015 09:29:37
[LAN access from remote] from 82.165.202.169:20 to 192.168.1.10:51364 Thursday, Feb 05,2015 09:29:34
[LAN access from remote] from 82.165.202.169:20 to 192.168.1.10:51363 Thursday, Feb 05,2015 09:29:32
[LAN access from remote] from 82.165.202.169:20 to 192.168.1.10:51362 Thursday, Feb 05,2015 09:29:29
Now I get stuff like this quite often, as I have some ports forwarded to my 4 PCs.  I don't worry about it, because all of them are firewalled, and I'm guessing these entries are usually the result of port scans.
However they are only ever on the the ports that I have forwarded, and I only have 1 forwarded to 192.168.1.10.  How can my router be forwarding traffic through to an internal address when there's no port forward for it?
Can anyone enlighten me?

Re: Weird LAN access in my Router Logs

Were you trying to download something using 'ftp' or from an 'ftp' server belonging to "1&1", at that time ?
If you are using Windows, then it could be that you need to change your browser 'ftp' settings in order for it to work properly ?

Ha! Of course!  Yes, it's the IP address of my 1&1 web page!  I was uploading some files on and off through that period now I remember.  However I wasn't using IE, I was using WINSCP.
That's the first time I've seen such traffic logged through the router though.
