2438	bad NAT performance (outgoing/uploading/writing speed drops to 0kb/s)	zyro		- Using WinXP Guest on Ubuntu 8.04 lts Host with Virtualbox 2.0.2.[[BR]]\r\n- Using NAT'ed Network Interface in Virtualbox[[BR]]\r\n- MRXMP.dll - Fix (http://www.virtualbox.org/ticket/1728) installed[[BR]]\r\n[[BR]]\r\nThe first Problem i encountered was MS Office terribly slow opening Documents stored on my Host shared folder. This issue was fixed by the MRXMP.dll (see above).[[BR]]\r\n[[BR]]\r\nBut now my issue is a extremely slow outgoing connection with the NAT'ed network interface.[[BR]]\r\n- Connection speed while uploading or transfer files from the guest to the network drops to 0 kb/s for about 1-2 seconds every 5-10 seconds.[[BR]]\r\n- This goes so far, that my network printer seems to have to take breaks because it does not get enough data to print continously[[BR]]\r\n[[BR]]\r\nAs far as i can tell, this problem must have sth. to do with NAT and the outgoing direction:[[BR]]\r\n- Downloads work at satisfying speed[[BR]]\r\n- Tried HostNetworkInterface (Bridged): No more lags/drops to 0kb/s [[BR]]	defect	closed	critical	network	VirtualBox 2.0.2	fixed	nat network write upload slow		Windows	Linux
