PF Question about firewall rule of ping?

[sdf]

Hello everyone,

When pinging a host, it is displayed in the firewall status table as follows

all icmp xxx.xxx.xxx.xxxx:8 <- 10.0.0.2:55555

Is 8 and 55555 here the port number? Ping does not use the port, is it?
The 8 here refers to the icmp type? 55555 is not a fixed value and will change at each ping.
Thanks.

There are no port numbers with ICMP.

Yes. But what is shown here?

What firewall, what fire status table, what programs are you using?

Obviously it shows an ICMP ping fragment. See also icmp(4) for an overview of the several ICMP package types.
