May 20, 2012scan comman line meaning
Hi All,
I'm new with irule. Does any one knows what this line means?
if {[scan [IP::remote_addr] {%*d.%*d.%*d.%d%%%*d} s4] != 1} { reject }
Appreciate much for your answers.
Thank you!

I think the intent of the scan command is to check if the remote IP address has a route domain in the format of 1.1.1.1%1 where each 1 could be any digit(s). - Spidey_29396
