80 порт снаружи доступен только для IIS, как открыть для других служб и приложений?

На 80 порту работает IIS, на 8080 Apache. Оба видны снаружи, страницы каждого открываются все ок.

Я ставлю certbot что бы сделать сертификат. По инструкции отключаю IIS, что бы certbot поднял на 80 порту свой вебсервер и получил сертификат. Но выдает ошибку Timeout during connect (likely firewall problem).

Я отключаю IIS, переключаю Apache на 80 порт, локально доступен, снаружи нет.

Windows Server 2008 R2 onwards Firewall Configuration for Parallels RAS

To use Parallels RAS on Windows Server 2008 R2 up to Windows Server 2019 with Windows Firewall enabled, several ports must be opened for the Parallels RAS components to communicate.

List of TCP and UDP Ports Used by Parallels RAS

The figure below shows the most common ports used by the Parallels RAS component to communicate when running on different machines:

Note: In Figure 1, the “>>” implies direction. If Server A is connecting to Server B, it will show “A >> B.” Therefore, you should open the following ports for the Parallels RAS components to work:

Gateway

TCP Ports 80 and 443

Publishing Agent

TCP Ports 20001, 20002 and 20003

TS Agent

VDS Agent

For a detailed and complete list of all the ports that the Parallels RAS components use to communicate, please refer to the Port Reference section in the Parallels Remote Application Server Administrator’s Guide.

Default Windows Server Firewall Configuration

The Windows Firewall is enabled by default on all profiles on a Windows Server operating system. The default configuration has the following rules:

• Inbound connections that do not match a rule are blocked.
• Outbound connections that do not match a rule are allowed.

The Windows Firewall configuration is already set to allow all outgoing connections; therefore, only ports for incoming connections should be opened. These must be configured in the “Inbound Rules,” as explained below.

Windows Firewall Configuration

There are three different ways to open ports in Windows Server 2008/2012 R2/2016 and Windows Server 2019. You can do so by using either:

• MMC
• The command line (netsh)
• PowerShell commands (only for 2012R2 and 2016)

Opening Ports on the Windows Server Firewall Using GUI

To open a port in the firewall using the GUI in Windows Server 2008/2012 R2/2016 and Windows Server 2019, follow the steps below:

1. Log in using an administrator account.
2. Click Start > Administrative Tools > Windows Firewall with Advanced Security

1. Click on Inbound Rules on the left of the MMC (Figure 3), and then on New Rule on the Right of the MMC (Figure 4).

Figure 3 Figure 4

There are five steps to open a port and accept incoming connections with the wizard:

• Rule Type
• Protocol and Ports
• Action
• Profile
• Name

For this example, we will open TCP port 20002 on servers that are running the Parallels RAS Publishing Agents role:

1. Rule Type section – select “Port” and click “Next”.
2. Protocol and Ports section – select “TCP” as the type of protocol and type “20002″ in the “Specific local ports” input field:
3. Action section – select “Allow the Connection” and click “Next”.
4. Profile section – select all three options and click “Next”. If you wish to limit the connection to a particular profile, select only the profiles that are appropriate to your setup. For this example, we will open the port on all profiles.

1. Name section – enter a “Name” for this rule. It is recommended to list the port number in the name, so the rule is easily recognizable. For example, the new rule could be named ”Pub_Agent_20002_IN”. Click ”Finish” when ready.

R epeat the above procedure for each additional port and/or protocol you’d like to open in each server.

Opening Ports on the Windows Server Firewall Using Command Line (netsh)

To open a port on the Windows Firewall using the netsh command line, follow the procedure below:

1. Login to the server using an administrator account.
2. Run the Command Prompt as Administrator.
3. Execute the following command to open the TCP port 20002 on the servers running the Publishing Agents role:

Below is an explanation of the format of the netsh command: Note: By default, netsh opens the specified port on all profiles. If you want to specify a specific profile, use the profile parameter: profile=public|private|domain

To open additional ports, repeat the above procedure for each additional port and/or protocol you’d like to open in each server.

Opening Ports on the Windows Firewall Using PowerShell

To open a port in the Windows Firewall using PowerShell commands, follow the procedure below (only applies to 2012 R2 and 2016 Windows Server OS):

1. Log in using an administrator account.
2. Run the Windows PowerShell as Administrator.
3. Execute the following command to open the TCP port 20002 on the servers running the Publishing Agents role:

Below is an explanation of the format of the New-NetFirewallRule PowerShell command:

Note: Default New-NetFirewallRule opens the specified port in all profiles. To specify a specific profile, add the –Profile parameter to the command with one of the following options:

Repeat the above procedure for each additional port and/or protocol you’d like to open in each server.

How to check if the Port is Open

To check if a port is open or not, you need to activate Telnet, which by default is not installed in Windows Server 2008, Windows Server 2012, Windows Server 2016, and Windows Server 2019. The easiest way to install the Telnet client is via the command line as follows:

1. Launch the command prompt as an Administrator

2. Execute the command below:

dism /Online /Enable-feature /FeatureName:TelnetClient

You can also activate Telnet via GUI if you follow the steps outlined in this link.

3. Next, check if a port is open by typing the command using the format below:

telnet [IP address] [port]

In the above command specification, the IP address is the IP address of the server hosting Parallels RAS. At the same time, the port is the port number, which in this case can be 20002. You can check the IP address of the local server by issuing the command below:

ipconfig

For example, if you execute the above command and find that your IP address is 173.20.39.40, you can check if a port 20002 is open or not by issuing the command below:

telnet 173.20.39.40 20002

When you see a blank screen, it indicates port 20002 is open on the server—meaning the test is successful. However, when you see receive a “connecting …” or an error message, it indicates port 20002 is not open on the server.

How to open a firewall port in Windows Server 2019/2016

Hello! One of the protection mechanisms of the server is the implementation of the Firewall. Although there are third party options, Microsoft offers a Firewall integrated into the operating system. It is very efficient and highly configurable. Additionally, it can allow or block connections or redirect connection requests. Also, by customizing the rules it is possible to allow only authorized communications. On the other hand, port management is vital within the Firewall. Since they allow communication between the server and the external network. In fact, the vast majority of attacks are carried out through these ports. For this reason, the Firewall blocks most of the ports. However, it is occasionally necessary for an app to have access to one. In this case, the administrator must authorize the program’s access to the required port. So let’s see how to open a firewall port in Windows Server 2019/2016.

How to open the firewall port using the advanced settings.

In the first place it is necessary to enter the Control Panel and follow the next path:

• System and security
• Windows Defender Firewall
• Advanced Settings

The advanced settings of the Windows Firewall are immediately displayed. There are the entry and exit rules plus the security rules for connections. Finally, there are the firewall supervision options.

Advanced Windows Server Firewall Settings

Clicking on the input rules will display the pre-configured Windows Server rules. As the name implies, they are related to incoming network connections and packets. Also, some rules are not activated by default. Therefore, you just need to double-click on them and then enable them.

Enabling a rule within the inbound rules.

Creating a new rule in the Windows Server Firewall.

By right-clicking on inboud rules, you can create a new rule.

Creating a new inbound rule.

There are several options for the creation of the rule. However, you should only select Port. Press Next to continue

Please select Port

Now it’s time to set your connection preferences:

• TCP: It is a connection-oriented protocol. In other words, its function is to create connections with the aim of sending data flow.
• UDP: It is a non connection-oriented protocol. Consequently, its development is based on the exchange of data grams.

On the other hand, it is possible to enable all ports for connection. This is obviously an unsecured option. Or you can configure specific ports.

Setting port connection values.

Now it is time to determine what action the new rule will take:

• Allow connection through the port.
• Allow connection if secure. That is, allow data to be transmitted only if the connection is authenticated through Ipsec.
• Block connection through the port.

Please select the option corresponding to Allow connection and press Next. Now it is time to determine which profiles the new rule will be applied to.

Please select the connection profiles for the new rule.

Finally, you can assign a name and description to the new rule. This way it is easier to locate it later.

Optionally you can assign a name and description for the new rule.

Back to the previous screen, you can see the new rule created.

Newly created inbound connection rule.

Ultimately we have seen how to open a firewall port in Windows Server 2019/2016. In addition, the tutorial also serves to block a specific port. This way, the administrator can increase the functionality of the Firewall. All right, that’s it for now. Greetings!
