F5 ASM Rate limit Requests based on Source IP

We have a situation where we would like to limit the number of requests form a particular IP to a web server seated behind ASM to 1 request per Source IP per second. Is this configuration option available via ASM configuration?

  • The short answer is no - you can do that fairly easily via iRules and the table ie add a table entry with a 1 second lifetime and if the client IP is present then deny access

    pseudocode:

    when HTTP_REQUEST

    if table entry

    drop/respond

    else

    add entry to table

    endif

    endwhen

     

    Do you want to do this for ALL clients or just a specific one?
