PAT does not work after a period of time

Core Issue

Both Network Address Translation (NAT) and Port Address Translation (PAT) are configured on the C1750 router and both work normally.

However, after 6 to 12 hours of operation, the PAT fails. No new PAT session can be established.

Power cycling the router makes PAT work again, but the problem occurs again after several hours.
