I have 2 servers that were in time sync until BM was set up on one.

They lost time synchronization, I assume it has to do with not being
able to reach a time source server.

In nwadmin, I can no longer access the BM setup, etc.., I get "The NDS
schema can not be extended, NDS error -659. Is this time synch problem

I found a coolsolutions feature article indicating private to public
source/destination ports 123 for udp need to be open.

Where/how do I create the filter?

(Obviously new to BM filters - never did it before...help!)
