as listed in the title - I have 3 opt interfaces that are no longer assigned but are still listed in the left hand window.
how do I remove them?
Solved - created a bunch of vlans and assigned them - it gave them opt3,4,5 and I then deleted them again
I solved this (seemed like a left over from a VPN client) by doing a backup, remove the entry von the config.xml and reimported the interface section only.
