[-- Attachment #1 --] You should isolate the problem. You could make some tests to understand where the problem is. So you could create a matrix that can help you to create all the possible cases to analyze if the problem is : 1) within your specific vm only 2) in any vm you create with virtualbox and linux (which distro ? changing distro may solve the problem) 3) on the network config of the host os (freebsd) (what version ? changing version may solve the problem) 4) any other combination that can exclude variables On Mon, Aug 14, 2023 at 11:35 AM Odhiambo Washington <odhiambo@gmail.com> wrote: > > > On Mon, Aug 14, 2023 at 12:30 PM Miroslav Lachman <000.fbsd@quip.cz> > wrote: > >> On 14/08/2023 10:49, Odhiambo Washington wrote: >> > 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? >> >> I never had this solved.
