iptables icmp error replay messages

hello all ,

if there is a way to reject the ICMP requests with a specific "string" or a specific type of errors ?

for example if we have a rule like that

Code:

iptables -A INPUT -s 192.168.10.12 -p ICMP --icmp-type echo-request -j REJECT

i have tried many types like host-prohibited and network prohibited instead of echo-request but it didnot succeeded so if there is a way to return a specific string or any error instead of port unreachable i will be thankful .

Code:

 --reject-with type

              The type given can be

              icmp-net-unreachable

              icmp-host-unreachable

              icmp-port-unreachable

              icmp-proto-unreachable

              icmp-net-prohibited

              icmp-host-prohibited or

              icmp-admin-prohibited (*)
