I am trying to use QEMU to emulate a x86_64 machine to run OpenBSD 6.9 inside FreeBSD 12.2-RELEASE with two tap interfaces. Hardware is an Intel Xeon E5450, 8GB DDR2, SATA SSD. This CPU doesn't have EPT support so I can't use bhyve and I don't want to use VirtualBox. I would like, if...
I have an issue with tap interface participating the bridge. The ]tap interface doesn't seems to receive anything, but it does send staff.
I have recently update the BSD
# uname -mrs -> FreeBSD 12.1-RELEASE-p7 amd64
Here is what I done:
# bge0 - lan interface
It is possibe to run lagg0 interface with lacp protocol from two tap0-tap1 interfaces?
tap interfaces used by OpenVpn.
I trying, but laggport flag not changed to active.
In failover proto work fine!
All offload options i removed from physical bge0 and bge1 interfaces by ifconfig -tso -tso4...
Is it possible to first test a bridge and tap, and maybe even a virtual network interface, before applying it to a VM? I imagine the virtual interface would not be the same one that the VM would create, but, this would be a nice troubleshooting step for getting bridged networking to work on...
I've set MTU to 3000 using the following commands.
ifconfig bridge0 mtu 3000
ifconfig tap0 mtu 3000
ifconfig tap1 mtu 3000
ifconfig vtnet0 mtu 3000
I've trapped data and get the MSS is 1358. So the above value is not close the 3000.
I created bridge0 (172.16.0.1) device with few tapX network devices (172.16.0.2-X) (bridged together by bridge0) for bhyve vms.
Then I created NAT (pf.conf), that solves networking via wlan0 (wifi card). Why? Because simple bridging doesn't work with wlan0/wifi interfaces (NAT works)...
