9371	NAT Interface fails -> fixed in svn	david		"I have searched bug tracker and found a few with similar symptoms, but resolved bug id's. For my situation, something must have changed after 3.16(the latest functioning version). Before I submit a new Bug I figured I would post here

Environment:
 * !VirtualBox 4.1.0 !r73009 win.x86
 * Host OS Windows 7 Release: 6.1.7600
 * Guest OS Linux 2.6.24

Problem:
 * All traffic from the guest OS(10.0.3.101) to the !VirtualBox NAT interface (10.0.3.2) fails after a duration of time.
 * Initially all traffic functions correctly, after approximately 15-20 min the guest OS is unable to contact the !VirtualBox NAT interface. No ping to !VirtualBox or anything else on the NAT interface of the guest. The guest is configured for two adapters. adapter 1 is a Host only network that continues to function normally when adapter 2 fails.

Attempted Resolutions:
 * I am able to restore traffic while the guest is running by changing the interface type to something other than NAT, and then reverting back to a NAT interface. This only leads to recreating the NAT failure again.
 * Restarting the guest also recreates the failure.
 * I tried changing the adapter driver types with no success.
 * Down grading to !VirtualBox 3.1.6 !r59338 is the only solution that provides continuous NAT connectivity."	defect	closed	network/NAT	VirtualBox 4.1.0	fixed			Linux	Windows
