Blocking ads via the Windows Firewall

Ad Blocker is a type of software whose purpose is to block advertisements that appear on websites. Chief among them is a browser add-on called AdBlock. The AdBlock mechanism includes many ways to identify advertisements and block them, among them by common words (ad for example), by behavior on the page and also by blacklists of IP addresses. In the next exercise, you must go to Magashim's B&B reservation website (http://34.218.16.79:1234) and with the help of the Windows firewall, reach a state where no advertisements appear at all. * Please note, if your browser already has an ad blocker running, you must suspend it before solving the exercise by clicking on Don't run on pages on this site. If you succeeded, attach a screenshot of the "clean" website. In addition, describe the rules you added and how you discovered that a letter should be added

I'm working on solving it myself, I should be able to give better feedback. Allow me a few minutes

Well, I was able to accomplish the task. It however wasn't in a very satisfactory manner. I used an ADBlock extension like mentioned. The one I used though just had me select elements on the site to hide, I didn't manually configure it at all. I assume this is a method of making it easier for most people to handle. I don't think that will be satisfactory for the description requirements

How to Block any IP Address on Windows and Mac
You can block an IP address from your computer on Windows or Mac. It's also possible to block IP addresses on your network via your router.

you don't want to block the port no, that would prevent all https traffic you want to add those ips to a blacklist

_null7mo ago

ok thanks ill try it do i need to incluse the ip:1234 or only ip
_null
_null7mo ago
not that ip, that is for the website. If you block that you wont get any of the content you need you want to selectively target just the ads
mayranch
mayranch7mo ago
but this ip addres are the image one
No description
_null
_null7mo ago
oh, yeah. just the ip that should cover all ports

mayranch7mo ago

_null7mo ago

mayranch7mo ago
there is no hhtp or https i can do maybe tcp and add port 80
_null
_null7mo ago
I believe its https so that wouldnt work just leave it on any, IPv4 would have been the optimal choice but its not on there oh I checked, it isn't https but its also not port 80 they are requesting on port 1234 if I remember from your image
mayranch
mayranch7mo ago
yea so just keep it on any?
_null
_null7mo ago
I think that's the best option, we might have to revisit that though
mayranch
mayranch7mo ago
ok

like this right now click next?
_null
_null7mo ago
no, switch the top one you want to select any ip address thats the local ip address it will apply to, ie the one that you are connecting to the internet with and the remote ips are the ips that you are sending a request out to.
mayranch
mayranch7mo ago
so i put the ip in the box down?
_null
_null7mo ago
yes I think you can add your whole list there
mayranch
mayranch7mo ago
and the avuka.net i just do nslookup and take the ip?
_null
_null7mo ago
or whois if that is one of the ads, then yes
