Is there any way to Ping to a PC in the other Network that using PAT ?

[pvanvu]

Example :

In IPV6 , there is no need for NAT , so a PC in other Network can Ping to another PC in another Network through Internet by using IPV6 address .

In IPV4 , we can Ping from a PC to a Server in other Network through Internet , because it was configured by Static NAT with a specific static inside Global Address .

-> But how can we ping from a PC in other Network to many other PCs in another Network though Internet since the Network was configured by PAT (1 to many) without a specific Network addresses like static NAT ?

I have one solution but I'm not sure like I use that PC , and just do a GG search " what is my IP " ? and use that IP address to let the Other PC to ping to my PC ?

-------------------
This my the Topo I"m working on it , everything was completely done , except I'm finding a way to Ping to PC1-4 which was configured by PAT

Thanks

This looks like homework.

Example :

Doesn't mean people don't have NAT and firewalls set up anyway. Theoretical capabilities of IPV6 are one thing, network security is another.

In IPV4 , we can Ping from a PC to a Server in other Network through Internet , because it was configured by Static NAT with a specific static inside Global Address .

It depends on the configuration of the routers and switches in between point A and B, and whether or not they forward ICMP packets. I can block pings within my subnet if I want.

Out of the box, most home routers, cable modems, and appliances don't respond to ping. Windows Server firewalls also ignore them. An increasing number of websites seem to be blocking that too.

Can't.

Won't work. Or rather, you're not pinging the thing you think you're pinging. (Look up how NAT works, and how port forwarding works, and how ICMP packets work and/or don't work w/r/t the previous two things.)
