ICMP

I am being plagued by WAN ping attacks every 10 minutes filling the error log constantly. These are from my SIP service provider's data centres. They say I need to disable ICMP in my firewall, but I can't see any option to disable it, only set a timeout state.
Hi @AlanCBC
Thanks for posting in our business forum.
IP scans are very common. Sometimes it is not an actual attack but a scan.
The ISP, your local government, or the national department may scan the network in your region. They may use the results for a security improvement.
There are also private scans from hackers and average people. This does not mean you are in danger. The block has been effective as long as you see the logs.
Disabling the ICMP would make your router stop responding to the ICMP tests. You cannot ping your public IP address as well. Note that.
