Can a firewall block ping?
Some firewalls will block ping signals by default.
For example, Windows devices have built-in firewalls which when enabled with default settings, will automatically block ping requests..
Is allowing ping a security risk?
The ICMP Echo protocol (usually known as “Ping”) is mostly harmless. Its main security-related issues are: In the presence of requests with a fake source address (“spoofing”), they can make a target machine send relatively large packets to another host.
Should I enable ICMP?
If you must filter ICMP, never filter ICMP destination unreachable or fragmentation needed packets; however, you may rate limit ICMP. Filtering ICMP will not lead to increased security, but it will make it more difficult to diagnose network issues and resolve configuration errors.
How does a ping work?
How Does a Ping Work? A ping is used to verify connectivity at an IP-level to a second TCP/IP device. It does this by transmitting Internet Control Message Protocol (ICMP) Echo Request messages and waits for a return message. Unless modified, the ping command will send 4 requests by default in Windows.
Should I disable Ping Wan?
You should not have any issue at all by disabling “ping”. The so called Ping is just another term for “IMCP Echo Request” or “ICMP Echo Reply” where ICMP is network protocol. … If you turn off “Ping from WAN” you simply tell your router that it should not care about any ICMP Echo Requests sent to you.
How do you troubleshoot ping failure?
If the pings fail to send, the command prompt will return basic information about the issue. You can use the tracert command to do the same thing, by typing “tracert 8.8. 8.8”; this will show you each step, or “hop,” between your router and the Google DNS servers.
What happens when ICMP is turned off?
With ICMP disabled, the host will not be aware of the most optimal route to the destination — causing the host to send data through excessive network devices, consuming unnecessary resources which leads to the reduction of network performance.
What port needs to be open for Ping?
Port 7 (both TCP and UDP) is used for the “echo” service. If this service is available on a computer, UDP port 7 could be used instead of ICMP to perform a “ping”. However, most modern computers don’t have the “echo” service running, so performing “ping” using UDP port 7 instead of ICMP would not work.

Why is ping not working?
It means that your ICMP packet (ping) was silently discarded with no response sent. That might happen for several reasons: Ping is disabled on router or (more likely) end point. Network is congested or misconfigured.
What port is ICMP ping?
ICMP has no ports and is neither TCP nor UDP. ICMP is IP protocol 1 (see RFC792), TCP is IP protocol 6 (described in RFC793) and UDP is IP protocol 17(see RFC768). UDP and TCP have ports, ICMP has no ports, but types and codes.
Should my router respond to ping?
Ping is a method to test network performance. Sending a Ping Packet to the WAN Port of a router, then the router is supposed to respond immediately. If there is no response or a delayed response, it means that the network is interrupted or the internet access is bad.
How do I know if my ping is blocked?
If it’s a local ping (you can’t ping your GW), take a look at the arp tables. After trying to ping, run “arp -na” to see if you got a MAC address for the IP you tried to ping. You can also try arping to to see if that works. But you’ll get the same information by pinging your gateway and then checking the arp tables.

The other option is that your ISP may drop ICMP traffic as a matter of course, or only when they are busy with other traffic.
