[-- Attachment #1 --] I had the following in sysctl.conf: net.link.tap.up_on_open=1 net.link.bridge.pfil_member=0 net.link.bridge.pfil_bridge=0 net.link.bridge.pfil_local_phys=1 So I only did: sysctl -w net.link.bridge.pfil_onlyip=0 sysctl -w net.link.bridge.pfil_local_phys=0 Nothing has changed for the linux VM. Windows11 VM is getting download/upload speed of 40Mbps/37Mbps while a Debian12 VM is getting download/upload of 37Mbps/45Kbps. Maybe there is an issue with the Linux itself?
