Reason for iRule Execution Error

What is the error message?

err tmm5[17765]: 01230140:3: RST sent from 10.16.240.15:443 to 192.168.25.56:49366, [0x2684cbf:1410] iRule execution error

You if statement is wrong, please try using this iRule, I've used a switch statement as it is less cluttered than several 'or' statements.

when HTTP_REQUEST {
    switch -glob -[string tolower [HTTP::host]] {
        "access.testxyz45.com" -
        "abc.testxyz45.com" -
        "def.testxyz45.com" -
        "mail.testxyz45.com" {
            persist source_addr [IP::client_addr] 255.255.255.255 600
        }
    }
}

Hi Yugandhar.

You have a syntax problem. your condition need to be explicit for each value.

you can't set one condition with multiple value. look what you should have done:

if { [string tolower [HTTP::host]] equals "access.testxyz45.com" or [string tolower [HTTP::host]] equals  equals "abc.testxyz45.com" or [string tolower [HTTP::host]] equals  "def.testxyz45.com" or [string tolower [HTTP::host]] equals   "mail.testxyz45.com" } {

persist source_addr [IP::client_addr] 600


} else { }  

By the way you have to optimise your irule by set your host variable:

set host [string tolower [HTTP::host]]

if { $host == "access.testxyz45.com" || $host  == "abc.testxyz45.com" || $host ==  "def.testxyz45.com" || $host == "mail.testxyz45.com" } {

persist source_addr [IP::client_addr] 600

} else { }  

and finally you have to optimize his irula for his execution as shown by lee:

when HTTP_REQUEST {
set host [string tolower [HTTP::host]]
    switch -glob $host {
        "access.testxyz45.com" -
        "abc.testxyz45.com" -
        "def.testxyz45.com" -
        "mail.testxyz45.com" {
            persist source_addr [IP::client_addr]
        }
    }
}

Try this one to see if there is a difference:

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] equals ( "access.testxyz45.com" or "abc.testxyz45.com" or "def.testxyz45.com" or "mail.testxyz45.com" ) } {
        persist source_addr [IP::client_addr] 600
    }
}

Will go bit different way to solve issue. It will be easy to add more url in datagroup

class

class host_url {
    access.testxyz45.com
    abc.testxyz45.com
    def.testxyz45.com
    mail.testxyz45.com  
    }

    when HTTP_REQUEST {
       if { [matchclass [string tolower [HTTP::host]] equals host_url] } {
       persist source_addr 255.255.255.255 600
         persist source_addr [] [] -- DevCentral Syntax

    }
}

I will request user to click iRule which working and solving issue. So that other can be refer.
