I can’t read meaning to the information i got from the packet sniffer print. What can i gain from studying the result of the packet sniffer and how do i get to understand it?
Maybe torch will give you better info
/tool torch
set interface=LAN
start
(wait a few seconds)
stop
/tool torch packet
print
This will show only the source and destination ips and ports. See if that is easier to understand.
Oh, Thanks
Touch was better. I stop browsing activity on my computer, I discovered from torch that some dst-address was pulling traffic, I wonder what application is using that. I want to stop all the activities on this particular ip address. I don’t care what it is (anti-virus update or microsoft product update) I just want to block it. How can I do that? Also there is this 255.255.255.255 address pulling traffic while internet activity is idle, what do i do about it?
Thanks
I would try this:
/ip firewall filter
add chain=forward action=drop src-address=xx.xx.xx.xx
Change src-address to the ip you want to block. This is based on the premise that the foreign ip is not trying to get into your router, which would be an input chain. If so, add this also:
add chain=input action=drop src-address=xx.xx.xx.xx
If you have any other rules in the filter, insure you insert these in the correct order. Order is important here. If they are not in the correct order, you can use “move”. Like this:
move 5 1
will move the item in line 5 to line 1, and the previous line 1 will become line 2 and move all below that down one line.
Thank you very much. You’ve been so wonderful and helpful. You’ve thought me so many things, but I’m use to winbox to manipulate the router, do you have any link to a tutorial on winbox usage?
To be honest, I use ssh exclusively. It is a habit from the ‘old days’. It should be under the tabs in the order of the directory in ssh. You should find the firewall filter rules under the “ip” section, then “firewall”, then “filter”.
Does anyone here remember Microsoft DOS 3.1? Holy Cow! Suddenly I feel old!
ADD: I remember discussing this with Moses while spending idle time around the burning bush. 
Lol…Thanks
That means, using command prompt is a habit you inherited from windows 3.1? I thought command prompt is more powerful, that is why many mature tech us it.
Thanks for everything.
Windows? Don’t need no stinkin’ Windows! 
There was no Windows when I got into this. There was no DOS. There was an Apple a couple years after I started this. Some of you must remember Steve Jobs, right?
My first experience with computers was July 1973 with three IBM 9020’s as parallel servers for the Federal Aviation Administration.
BTW, you are welcome!

I came into existence 12 yrs later.. came in contact with computer in 2004. That shows the difference.
