18.1 Legacy Series / Removing (removable) interface results in broken system
« on: April 29, 2018, 02:49:21 am »
Hi,
I recently played around with an OPNSense box with an attached USB network interface. Everything was fine, until I removed the usb interface during operation. After that, the whole system became non-operational.
I investigated this and it seems that removing the interface resulted in a reboot, but since on the next boot the system noticed that something has changed in the interfaces, it has reset all interfaces to default. I understand that this makes sense security-wise, but especially in cases where
- removable interfaces are used and
- these interfaces are neither configured as lan or wan but as some optional interface
resetting *all* interfaces just because one was disconnected seems a bit over the top to me. And yes, I know that one gets asked on the next boot, but this is only visible on the local console...
Is this behavior really intended to be this harsh?
