Who has broken the firewall? Without allowing outgoing ICMP Request ping leads to “General failure”.Īllow ICMPv4-Out in Outbound Rules. Which dude has deactivated the IPv4 Procotol and why? Nobody knows… Without activated IPv4 Protocol ping returns “General failure”.Īctivate the IPv4 Protocol in the settings of your network card (ncpa.cpl). Configure a default gateway, which is in the same subnet as your host. This is useful for diagnosing datadependent problems in a network. But that is not the case, the router is in the network 192.168.1.0/24 and thus in another subnet. ping can also send IPv6 Node Information Queries (RFC4620). That means that every IP address of the gateway in the range 192.168.0.1 – 192.168.0.254 is ok. In the sample screenshot, the IP address of the router or default gateway should be located in the network 192.168.0.0/24, because the client is on this network. If this is not the case, Windows reports “General failure”. The router must be in the same subnet as the “pinging” host. In the screenshot below, the computer knows what to do, because there is a routing entry for the default route and the IP Address of the default gateway is present. To keep it simple: The computer does not know what to do with the ICMP packet. This happens, when the computer tries to reach a host outside it´s own subnet. If the default gateway entry is missing, the message “General failure” could appear. In this arcticle, I describe the most common configuration errors, which cause the general failure. Ping tests the network connectivity between systems. What to do if ping returns general failure? One of the most common command line tools on all platforms is the command ping.
