I have a small branch 871 which is about 1800km away from me. I want to remove the complete ZBFW from the router (configured through SDM once) and start from scratch. Obviously I don't want to lock myself out, although there are people onsite who can reset the router in necessary, I'd like to avoid having to ask them.
Can I just do a 'no zone-member security out-zone' on the outside interface and then follow with the other 2 LAN inside interfaces?
Thanks in advance!
