– I have all the corresponding ports opened on the router – I have everything in the Windows firewall settings set to allow said ports; I even totally deactivated the windows firewall AND the router firewall – still every port I check is displayed as filtered.

Port state filtered

These actions are generally controlled by the IPtables firewall the system uses and is independent of any process or program that may be listening on a network port. Beyond the firewall, a program or process (a server or daemon) may be listening on a port or not Port is produced from grapes grown and processed in the demarcated Douro region. The wine produced is then fortified by the addition of a neutral grape spirit known as aguardente to stop the fermentation, leaving residual sugar in the wine, and to boost the alcohol content. Filtered ports are the result of a packet filter or firewall. When no response at all is received from the remote device, the port is considered to be “filtered.” Since a response isn’t received from the port, Nmap often retries communication to the port to ensure that the packet wasn’t simply dropped due to error or congestion. Re: port state Filtered service HTTP server ubuntu 16.04 You have not showed us enough information, nor formatted it properly.

Closed Port: If you send a SYN to a closed port, it will respond back with a RST. Filtered Port: Presumably, the host is behind some sort of firewall. Here, the packet is simply dropped and you receive no response (not even a RST). Open Port: If you send a SYN to an open port, you would expect to receive SYN/ACK.

Filtered is described in the NMAP Reference Guide, Chapter 15: Nmap cannot determine whether the port is open because packet filtering prevents its probes from reaching the port. The filtering could be from a dedicated firewall device, router rules, or host-based firewall software. Nmap places ports in this state when it is unable to determine whether a port is open or filtered. This occurs for scan types in which open ports give no response.

This occurs for scan types in which open ports give no response. The lack of response could also mean that a packet filter dropped the probe or any response it elicited.
