Hi, we observed problems with Windows Update Services and Uploading Files from a Windows System to other systems. We tracked this down to IPv6 connections only. IPv4 and IPv6 in Receive direction seems to be not a problem. It turned out that setting TCP/UDP Checksum Offloading for IPv6 from "RX/TX enabled" to RX "enabled" in the Network Driver settings solved the issue. I remember similar problems existed with Linux some time ago. Linux guests on the same host are also not an issue.
Is this a known issue? I tried latest and stable drivers from the Fedora Website. Thanks, Peter
