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.
  
• Using NAT'ed Network Interface in Virtualbox
  
• MRXMP.dll - Fix (​http://www.virtualbox.org/ticket/1728) installed
  

The 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).

But now my issue is a extremely slow outgoing connection with the NAT'ed network interface.

• 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.
  
• This goes so far, that my network printer seems to have to take breaks because it does not get enough data to print continously
  

As far as i can tell, this problem must have sth. to do with NAT and the outgoing direction:

• Downloads work at satisfying speed
  
• Tried HostNetworkInterface (Bridged): No more lags/drops to 0kb/s
