Blocking wp-login on wordpress ..

Hi All, I need to block the access on wp-login resource from external ip.

 

I try this Irule :

 

when HTTP_REQUEST { if { ! ([IP::addr "10.0.0.0 mask 255.0.0.0" equals [IP::client_addr]]) } { log local0. "Client IP: [IP::client_addr]" switch -glob [string tolower [HTTP::uri]] { "/admin" { log local0. "ADMIN" drop log local0. "Dropped admin [IP::client_addr]" } "/wp-login" { log local0. "LOGIN" drop log local0. "Dropped login [IP::client_addr]" } default { return } } } }

 

but doesn't work the drop instruction.

 

I try the HTTP::respond 403 content {Not Authorized 403 !} command but I don't have (or I don't know) how enabling HTTP profile on VS.

 

I have this final version "BIG-IP 9.4.5 Build 1049.10 Final" and on pool I have SNAT option.

 

Any suggestions ?

    If you do actually have a HTTP profile assigned, try this (I've just tidied up the test expression);

    when HTTP_REQUEST {
  if { ! [IP::addr [IP::client_addr] equals 10.0.0.0/24) } { 
    log local0. "Client IP: [IP::client_addr]"
    switch -glob [string tolower [HTTP::uri]] { 
      "/admin" { log local0. "ADMIN" drop log local0. "Dropped admin [IP::client_addr]" } 
      "/wp-login" { log local0. "LOGIN" drop log local0. "Dropped login [IP::client_addr]" } 
      default { return } 
    }
  }
}

    If you don't have a HTTP profile assigned, change the event to 'when CLIENT_ACCEPTED'.

      OK, great. As noted by JR, you could reverse that and change the event to save a few CPU cycles etc.

    Hello friends, I am working on WordPress and also looking for the same. However the process mentioned here is not working with my theme as it still shows error. Should try any security plugin or instead go for hand coding. As I am not so much code savvy, hence kindly reply it in simple manner.
