winxp limited guest networking on ubuntu 8.04 amd64

Description

When running VB 2.1.0 on my Ubuntu 8.04 LTS AMD64 host machine, networking is crippled for Windows XP SP3 32bit. Setting the MTU for the virtual network interface to 1450 in the windows registry seems to resolve the issue.

Symptoms are:

  • able to ping (packets up to 1468 bytes)
  • dns lookups go though fine.
  • telnet sessions work fine as well.
  • IE http traffic fails.
  • CIFS traffic can discover shares, but not browse them.

Installing or uninstalling Guest Additions doesn't affect the situation.

After some more testing, the highest MTU I can go to is 1496 (1468+28 for IP/ICMP headers). Maybe this is a magic number for someone that rings a bell?

The issue seems to arise with the PCnet-FAST III adapter in bridge mode. I've not tested this with any other adapter type or interface mode.

I assume you are talking about a host network interface setup, right?

Yes, this was happening on the host interface setup indeed. I'm not sure if this is still happening, I'm suspecting it was resolved in either 2.1.2 or 2.1.4.

Is there a way for me to close this ticket if it's resolved?
