In the following scenario, it may not work to copy a file from the private network to a server on the public side of the Network Address Translation (NAT). The file name is created on the outside server, but the length of the file may be 0 bytes, or the content of the file may be blank.
When the MTU of the public network adapter is less than the setting on the package from a client on the private side of the NAT, the NAT sends an Internet Control Message Protocol (ICMP) "Destination unreachable" packet back to the client to indicate that the defragmentation is needed. NAT does not send the ICMP package to the client, but instead sends the packet to the public network adapter of the NAT.
