Windows 10: D-link DIR-635 intrusion

I have a D-link in my summer house and connect to a micro Arduino just to control the heat.
So I set a port forward to the local IP of my micro in D-link.
I have blocked in D-link config all subnet but the one I connect from at my flat in my city living.
Seems ok that a lot of connections from various IP to port 80 is blocked when I check the D-link Log.
It's like 5-10 blocked connections per minute. Guess that's what to be expected .....

Still I find when managing the D-link from WAN and checking current Internet sessions that most of the time I see one EST (established) connection from stocastic IP's not within my subnet from home. With TCP timeout 1sec - 2 hours.
My problem with this is my VERY crude webserver on the Arduino "webserver" get confused when there is multiple active connections to it's port 80. I can connect like for a starter from city home. But after like from 2 hours - 1-2 days I can not connect anymore. So I'm thinking maybe these intruder connections is the problem.

I don't understand how these connections get through my blocking.
I can only guess .... Security problem with the D-link ???
Any idea on this

D-link version (pretty old I think) :
Firmware Version: 2.20EU
Hardware Version: B1

dir Difficulties

DIR uses whatever time definition you tell it to use. Following command would list all files and folders in X:\Downloads in order they have been created:

dir X:\Downloads /t:c

DIR is fully capable to sort files and folders. Following command would list all files in X:\Downloads, oldest first:

dir X:\Downloads /o:d

The minus sign before a parameter reverses the results, so the following command would list the same folder in reversed order, newest first:

dir X:\Downloads /o:-d

You can also combine switches. Following command would list all files and folders in X:\Downloads and all its subfolders (the /s switch), listing them in newest first based on time of file / folder creation:

dir X:\Downloads /s /o:-d /t:c

 

D-Link DIR-615 or NETGEAR WNR2000

I currently have the NETGEAR and got $30 coupon from a company called Mwave because they sold me an incompatible laptop battery.

Thinking about grabbing the D-Link DIR-615 from their website and selling one of the routers.


Which should I keep?

 

dir Difficulties


I am getting the hang of this command set.

Maybe somebody know a work around that will list the three time stamps at one time.
Theoretically dir /TC /TA /TW.
dir will only show one of the three at one time.

To me it seems that the only way to get all three on a line is to run loop with output to file, then boiling down the three outputs to one line. Clumsy but maybe the only way to get the job done?

Thanks for any suggestions.
