I have one Question upto how may private host we can assign NAT OVERLOAD to map the internal private ip address to the ports.
I understand normally we do not require that much of ports to map to access the private home/office computer from remote.
However for my knowledge i would like to clear this doubt.
let consider being patient one admin/network guy configure 50 PORTS MAPPED TO 50 INTERNAL IP ADDRESS to access 50 computers remotely. what if 200, 300, number of ports need to map the ip addresses WITH ONE PUBLIC IP ADDRESS, is there any other solution or any advanced NAT methods.
Guys i may need to clear some more doubts after your replies.
I appreciate your suggestion and replies and thanks in advance.
