Hello,
I*m relativley new to Unix, Shell and FreeBSD. So, please, please, are not to angry with me, if my question is stupid. I did allways some internet-research, but could not find any answers to my problem.
I'm running 12.1-RELEASE-p5 FreeBSD 12.1-RELEASE-p5 GENERIC amd64 as guest in VirtualBox 6, with one virtual nic attached.
My goal is, to create a virtual network-stack. So I play with the system, to learn, how to do things. Actually I try to create several virtual devices.
in loader.conf I have
But, when I create more than one virtual device in rc.conf, f. e.
or
or
if I do something like this
the result will be always the same: ifconfig always only shows the last cloned interface in the list
like this
where "bridge1" will be epair0 a/b or bridge1, depending, on what is the last created device in rc.conf. Bridge0 will be only shown there, if there are no other devices created in rc.conf. Even a "ifconfig bridge0" will show "ifconfig: interface bridge0 does not exist" in the other cases.
But if I create a bridge manually, like "ifconfig bridge0" will create that, and list it, if I give a "ifconfig" in the terminal.
What could be / is the problem, how to solve it?
