Do I just need to forward this port?

[Cander]

yeah you can forward it to whatever computer on your network is to be pinged

When you ping someone you send them ICMP (Internet Control Message Protocol) echo request packet

In repsonse the host you have sent the echo request packet to should reply with none other than an echo reply ICMP packet.

The ping utility generates output simillar to this:

PING 192.168.0.3 (192.168.0.3): 56 data bytes
64 bytes from 192.168.0.3: icmp_seq=0 ttl=128 time=0.3 ms
64 bytes from 192.168.0.3: icmp_seq=1 ttl=128 time=0.3 ms
64 bytes from 192.168.0.3: icmp_seq=2 ttl=128 time=0.3 ms
64 bytes from 192.168.0.3: icmp_seq=3 ttl=128 time=0.3 ms

--- 192.168.0.3 ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 0.3/0.3/0.3 ms

The purpose of the pinging is to determine network connectivity with another host. If the echo request doesn't get a reply, it means the host cannot be reached.

ICMP doesn't use ports. You just need to accept/forward ICMP packets.

I've never been connected to a Newtwork either :lol: But if you are connected to the internet you can ping other computers.

Whether or not they send you a reply is another story. Many hosts block ICMP packets from the internet becuase malicous users flood them with pings from spoofed addresses.
