NetDebug

This module has multiple cmdlets and functions oriented towards debugging network reachability and ISP issues. The *NetListener family of cmdlets allow you to create network listeners for UDP and TCP ports. These listeners can be configured to run PowerShell scripts and process incoming traffic, serving as simple PowerShell servers. Test-NetFlow is a modified version of Test-NetConnection which adds the ability to verify UDP connectivity. Resolve-ASN provides information about the Internet Service Provider of a specified host. CheckPoint-NetIPsecMainModeSA allows you to identify ISP information on who you are connected with. Many Xbox Live enabled experiences will generate IPsec SAs which can be tracked with this tool. Get-NatType simulates Teredo interactions to provide you information on the local NAT and firewall configuration.
