ASL timed out a couple of times but it made the changes anyway after a while, it took a long time to process though? The same happend after I added al blocked IP's to the blacklist, i timed out also a couple of times. I will try it again tommorow but right now if I add one blocked IP to the blacklist it is taking minutes and you have to wait nothning else works at if this process is running...
yeah it can take a long time if you're building a huge policy. It has to do with maintaining compatibility with other firewall systems (psa-firewall, apf, etc). Long term for performance sake, I might have to break that. Basically it analyzes the existing policy to make sure its not conflicting with it, and that takes a long time with a big list.
I tried it again just now and it is impossible to move/copy the blocklist IP's to the blacklist ASL is timming out and during this process everything is on hold.
