    I need to be able to delete ARP cache just for VPN connections (virtual TUN network adapater), but not for local ones. How can I do that? I can only find commands to delete/flush all of ARP cache or ARP cache per-IP. I need commands per-interface...

    Nevermind... (netsh interface ipv4 delete neighbors "Interface")

    Hmmm... Sometimes that command works, but other times it says "The parameter is Incorrect".

    Same goes for "arp -d" command. Sometimes it works, but other times it says "The parameter is Incorrect". Any ideas? Isn't NetSh depreciated by now?
