You may be wondering what do I put in global port range? First, you need to know that there are three main types of ports, Default single port range, Dynamic ports, and Registered ports. These are all necessary for your server. However, if you are not sure which type of port to choose, here are some general tips to help you get started. Here is a quick overview of all three types of ports.

Default single port range

The default single port range in the global port range can be adjusted with the netsh command. In the example shown, the port range is set to 65535. The range can have a minimum value of 0 and a maximum value of 255. However, if you need more than that, you must create a custom range. This will make the ports in your global port range bigger than the default one.

The default single port range in global port range can be configured for source NAT pools that support port translation. This default port range is the default port range, which is 1024 through 63,487. Similarly, the global port range can be configured by specifying pool-default-twin-port-range. Using these commands, you can configure the default port range of your NAT pool. These instructions apply to source NAT pools.

Dynamic ports

There are two types of port numbers available to the Internet. One type is known as static and the other is known as dynamic. Dynamic port numbers are never reserved or assigned and are used for temporary or private purposes. There are many systems that do not use dynamic ports, but software vendors can register application port numbers with ICANN to ensure that other applications respect the values registered. Listed below are the two main types of dynamic port numbers.

You can specify a port range by using the Multi-String Editor dialog box. The range must be entered in xxxx-yyyy format. You can also specify a single port with the same value for x and y, for example, 4000-4000. Windows Server 2008 and Vista introduced the new dynamic port range for outgoing connections. The new default start and end ports are 49152 and 65535, respectively.

Registered ports

Registered ports in the global port range are known to be available for any application. The port range is based on the TCP/IP protocol. There are two main types of port numbers: dynamic and privileged. Dynamic ports are known as private ports and are not commonly used. Registered ports are used by software vendors who register their application ports with the IANA. They must abide by the registered value. The range of privileged and nonprivileged ports is standardized.

The default range for ephemeral ports is 49152 through 65535. These ports are primarily used for FTP served to the outside world. Other uses include passive “PASV” data connections and non-passive FTP client access. Higher-numbered ports are less likely to be used for system services. The lower-numbered ports are generally assigned to well-known services. Changing the global port range can benefit automatic network address translation and firewalling.

Privileged ports

The Privileged ports in global port range property is an important security property that allows you to control which processes can access these ports. It prevents regular users from using these ports for running servers. This means that only root users can run servers on privileged ports. However, any user can use privileged ports to run a SOCKS server or Web proxy. To enable privileged ports in global port range, you can use the dacinet setpriv command. You must specify the privileged ports to the property /etc/security/priv.

The range of privileged ports includes the well-known and dynamic port numbers. Well-known ports cover the 0 through 1023 port numbers, while dynamic and registered ports are the ones between 49151 and 65535. Dynamic and registered port numbers are used by privileged users and systems. The table below shows registered UDP and TCP protocol numbers. You can find out more about the ranges by using the following table.

NAT pools with port translation

The Network Address Translation (NAT) destination pool window displays summary information. You can specify the NAT pools for a specified logical system, all logical systems, or all of them. The output fields are listed in approximate order of appearance. They include the total number of destination NAT pools and NAT rules in the logical system. Each destination NAT pool defines a subnet. The subnet contains all the logical systems in the domain.

To verify that NAT is being applied to traffic, enter the show security flow session command. This command displays the IP addresses of all active sessions. It also displays the policy name and ID. NAT is enabled by default when both the global and local address pooling are enabled. You must also configure a security statement before enabling port translation. This step is necessary before configuring NAT pools. Depending on your network environment, you may want to configure the NAT pool configuration to allow only specific traffic.
