Hi Alan, thanks for the answer, I have some doubts:
The module returns FAIL if it can't assign an IP address.
What happens after that depends on your local configuration
What do you mean with "depends on your local configuration"?
Which comes from where?
That is the point: the customer takes an IP from the pool without
allocating the pool. Maybe is something related to the above question?
Meaning is there something I miss to "block" a user on sqlippool module
And another thing I noticed:
we have some expiry_time way back in the past, but the ip is correctly
assigned in NAS:
What could it be?
