Cisco Packet tracer I did dynamic nat configuration, configures ips did ip route, configured frame relay and other necessary stuff and all devices are pinging to and from and responding well. So immediately I configures NAT those on outside can ping me but I can't ping them even packet but the nat translation is working as I saw result. And I later figure out that when I remove only ip nat inside it pings to and from and after I re-input the command can't ping to but others can ping to me so I want to ask if that how it should be or there is other problem. Have rechecked to see if there is any problem will provide the picture also
