SYMPTOMS
Internet Connection Sharing (ICS) Network Address Translation (NAT) functionality stops working after 50 percent of the public network DHCP lease has expired. When this occurs, each network adapter on the NAT host can ping hosts on its corresponding network, but the private network cannot ping public networks by using the NAT host. The NAT host public interface does not forward replies from public hosts to the private network.

Releasing and renewing the address resolves the problem, but only until the next DHCP lease time-out event occurs.



CAUSE
This situation occurs because the DHCP Net Table Entry (NTE) in the routing table is set incorrectly after 50 percent of the lease time has expired. This causes all packets to be delivered locally instead of being forwarded to the private interface.
