After update to 18.7.7 i receive this message in captive portal and defined adresses/mac not allowed:
captiveportal: Traceback (most recent call last): File "/usr/local/opnsense/scripts/OPNsense/CaptivePortal/cp-background-process.py", line 218, in main bgprocess.db.update_accounting_info(bgprocess.ipfw.list_accounting_info()) File "/usr/local/opnsense/scripts/OPNsense/CaptivePortal/lib/ipfw.py", line 104, in list_accounting_info stderr=devnull) File "/usr/local/lib/python2.7/subprocess.py", line 190, in check_call raise CalledProcessError(retcode, cmd) CalledProcessError: Command '['/sbin/ipfw', '-aT', 'list']' returned non-zero exit status 71
For now i downgrade back to 18.7.6...
This is a user forum, so I think the developers do not actively monitor on issues. You should raise your issue with the code repository at Github. There it will get more focus:
