Keep "tap" interface after reboot? (bridge member)

daemonix

Hi,

How do I keep a tap interface I created there after reboot?

I did a simple "ifconfig tan0 create" then on GUI I enabled it, made a new bridge and set tap and another interface as members. Nothing special.

I also added "net.link.tap.up_on_open=1" to /etc/sysclt.conf

But! After reboot tap is gone and net.link.tap.up_on_open is 0!

Any ideas?

pfSense uses neither rc.conf nor sysctl.conf(dircertly) so that won't work.

sysctls need to be entered in Sys > Adv > System Tunables. That list is stored in the config and overwrites the file at boot.

What exactly are you trying to do?

@stephenw10 Ive been testing freebsd bhyve on a testing system I have (I know its not recommended on a firewall etc!)

I created a tap0 so VM can attach to it and added it to the "LAN" bridge together with the physical ethernet port etc (all this from GUI).

On reboot tap0 is gone.
I added the net.link line on System Tunables but I need to find a way to keep tap0 alive through reboots.

Is there a way to hack it in?

Thanks

You can probably add it with a shellcmd. It might need to be an early shellcmd.

When I have done this before I used a script that created the tap adapter and lauched bhyve against it. It's been a while though!
