    Internet Connection Sharing and firewall rules


    Hello,

    I've recently started using internet connection sharing between two network adapters on my desktop. However I noticed the adapter which the internet is being shared to is not respecting the firewall rules I have in place.. its bypassing all the set firewall rules.

    Is this intended behavior? Was a surprise to me..

    I would like to share my connection to a secondary adapter however I require it to respect the firewall rules I have in place.. I'm not entirely sure the simplest way to go about this.

    My end goal is to control the secondary adapters network access (specifically blocking certain IP addresses/ranges).. I really like the fact windows firewall allows me to punch in terminal commands to setup new rules with ease, which is why I have opted to go down this route (internet connection sharing).

    This is a home application, I own a router/modem combo supplied by the ISP which is very limited in its capability..

    Can anyone suggest a way I can force ICS to respect my firewall rules? or perhaps a alternative solution (preferably software route).

    Windows version number: 1903 (build 18362.1016)

    :)

    Is it possible to share internet connection via remote desktop?

    RDP is not capable of Internet sharing, so you can't share Internet using RDP with standard applications. There are many way to share Internet from a Windows box to another one. I suggest you to use VPN. You should do following steps:

    1. Run VPN Server on your server with unlimited internet access
    2. Connect to VPN server from your limited computer

    Windows Firewall Forgetting Rules

    I've recently installed the latest version of Windows 10 in my PC. I've blocked and allowed some softwares in Windows Firewall. But Firewall keeps forgetting the rules in 1/2 days. For example, I've allowed Pro Evolution Soccer 2016 in Firewall. But in a
    few days, when I open the game, firewall sends message asking if I want to allow that app or not. Then after checking the allowed apps, I do not see that game in the list, which means firewall didn't remember the settings.

    Also, I blocked KMPlayer in firewall to prevent it from connecting to internet (it shows too much ads otherwise). So, I created inbound and outbound rules for KMPlayer and blocked the connection. After that, it was all okay for two days, then again it started
    showing ads, and then checking the rules, I didn't notice the rules there which I created two days ago. And this thing keeps happening. I make the inbound and outbound rules for KMPlayer, it stays all okay for a few days, and then it forgets again.

    So, what is wrong with the firewall and what is the solution of it?
