Over the Christmas break, I had a few hours to spare and tackled a few issues in some of my PowerShell modules. I’ve released Posh-SYSLOG 3.2 as a resolve of this.
This version removes the need to call Get-NetAdapter that's contained in the NetTCPIP module. The reason why I wanted to remove this dependency is to allow Posh-SYSLOG to run on PowerShell 6 (at least on Windows to start with).
