Converting A10 aFlex rules to F5 iRules

Hi,

We are moving onto F5s and Im having an issue with an irule

The A10 aflex rules are as follows

 

A10

when HTTP_REQUEST {
 set uri [string tolower [HTTP::uri]]
   if { ($uri starts_with "<.url>") and not ([CLASS::match [IP::client_addr] Test_IPs1 ip] or [CLASS::match [IP::client_addr] TestIPs2 ip] ) } {
      drop
 
}}

And I'm trying to implement this on the F5 with

 

when HTTP_REQUEST {
 set uri [string tolower [HTTP::uri]]
   if { ($uri starts_with "<url>") && ([class match ne [IP::remote_addr] Test_IPs1 ] | [class match ne [IP::remote_addr] Test_IPs2 ] ) } {
      drop
   } 
}

 

When I apply this irule to the VIP i can no longer access the URL behind that VIP

 

Only IPs that should be allowed through should be in Test_IPs1 or Test_IPs2

 

Anyone know how the F5 rule should look?

Thanks

Adrian

    Hi adrianglendinning your class syntax is a little off. Try this:

    when HTTP_REQUEST priority 500 {
    if { [string tolower [HTTP::uri]] starts_with "/my/url/here" &&
         ![class match -- [IP::client_addr] equals Test_IPs1] && 
         ![class match -- [IP::client_addr] equals Test_IPs2] } {
            drop
         }
}

    also you can combine those two classes into a single class to simplify the condition a little unless there's a good reason to keep them separate.
