iRule to limit access to webserver directory by client IP

I try this

when RULE_INIT {
log local0. "Init redirect Https V2" 
  array set ::http_allowed_ip_list { 
"10.0.0.11/12"
"10.0.0.12/13"
  }
}
when HTTP_REQUEST {
log local0. "IP [IP::client_addr] Tries to connect" 
if { ( not ( [ matchclass [IP::client_addr] equals $::http_allowed_ip_list ]  ) ) } {
    HTTP::redirect https://[HTTP::host][HTTP::uri]
}
}

but I have an error

TCL error: Rule redirection_https_v2 - can't read "::http_allowed_ip_list": variable is array while executing "matchclass [IP::client_addr] equals $::http_allowed_ip_list

I suppose this is because I don't declare well my array

but it seems I have no error during init

any help appreciate

thanks
