Hi,

 

this list can be uploaded as an ifile. You can also do a lookup using sideband connections in irules

You can create an ifile using the following command : 

tmsh create sys file ifile blacklist source-path http://hostname.com/uri

and then update it using the following command : 

tmsh modify sys file ifile blacklist source-path http://hostname.com/uri

The filesize for a single iFile was raised to 32Mb in 12.1.0. Prior versions limited the size to 4Mb.
