I am configuring a firewall hardware, which is connected between my laptop and lab LAN (lab LAN is also connected to other computers as well as Internet). My objective is to allow the ping between my computer & another computer in the lab. Then test deny the ping function.
To ping successfully, I must allow all necessary protocols that related to "ping" by setting firewall configuration GUI. I have tried to allow several protocols together that related to ping, such as ARP, ICMP. However, "ping" is unsuccessful. I think the problem is that some protocols that support "ping" are not listed and allowed in the configuration. Is it correct? Then what protocols I need to add as well?
