Windows 2003 unicast NLB - unicast packets don't get in

Reported by: ma3x Owned by:

Version: VirtualBox 2.2.4 Keywords:

Host type: other

Description

Windows 2003 R2 EE as a host and a guest via bridged adapter. VBox 2.1.4 and 2.2.4.
The guest is setted up with NLB(Network Load Balancing) in unicast mode. Pings(and all other unicast packets) from and to guest aren't finished successfully. I try to sniff this situation with Wireshark on the host and on the guest:
1) On the host I see:

  • when pinging the guest - echo requests to the guest without reply
  • when pinging someone from the guest - echo request from the guest and echo reply from the destination

2) On the guest I see different incoming broadcast packets and outgoing unicasts, but not incoming.
When NLB is switched off, network is working good. I tried to change MAC address in the VirtualBox guest settings to the cluster virtual IP - no success.
I've found the same problem on the  forum topic about 2.1.4 release but there is no answer. Do I need to downgrade to 2.0.2?
