Internet filtering is a popular way to protect computers and networks from unauthorized access, but it can be difficult to configure a firewall to allow Internet access. There are several ways to allow Internet access through a firewall:

1. Use a proxy server. A proxy server is a computer that acts as an intermediary between your computer and the Internet.

When you use a proxy server, your computer sends all of its requests to the proxy server, which then sends the requests on to the Internet.Proxy servers are useful when you want to bypass a firewall because they allow you to access the Internet without giving away your true IP address.

2. Use a virtual private network (VPN). A VPN is a technology that creates a private network connection between your computer and a remote server.

When you use a VPN, your computer sends all of its requests through the VPN server, which then sends the requests on to the Internet. The VPN server can then encrypt the traffic so that it is not readable by anyone other than the VPN server and the computer it is connected to.

3. Use a proxy server and a VPN.

If you want to allow access to certain websites while still protecting your computer and network from unauthorized access, you can use a proxy server and a VPN. To do this, you would create a VPN connection to the proxy server, then use the proxy server to access the desired websites.

4. Use a firewall.

A firewall is a device that protects your computer and network from unauthorized access. You can use a firewall to allow access to specific websites or networks, or you can use a firewall to allow access to the entire Internet.

5. Use a rule-based firewall.

A rule-based firewall is a more advanced type of firewall that allows you to specify which websites or networks should be allowed access to your computer. You can create rules for network traffic, email traffic, or Internet traffic.
