Stop users accessing website via IP address

[Puneet]

Hi Stephen,

 

I think I did not stated the problem correctly.

 

Let me explain the issue:

Say, my website www.mywebsite.com <http://www.mywebsite.com>  is hosted on
IP : 167.123.98.20

Now the Users could type in the IP address i.e. 167.123.98.20 and access my
website as the server is listening at port 80.

 

Now, if any user does that, I want to redirect the Users to
www.mywebsite.com <http://www.mywebsite.com> .

I don't want any User transaction to be done using 167.123.98.20.

 

Therefore I had the following code in place.

 

//If the User access my website using the IP address

vcl_recv() {
     if(req.url ~ "167.123.98.20") {
     error 750 "Moved Permanently";
  } } 

 

Redirect the user to www.mywebsite.com.

sub vcl_error {
    if (obj.status == 750) {
    set req.http.X-REDIRURL = regsub(req.url,"https?://[^/$]+", "
<http://www.linkedin.com/redirect?url=http%3A%2F%2Fmywebsite%2Ecom&urlhash=5
qRF&_t=tracking_anet> http://mywebsite.com");
    set obj.http.Location = req.http.X-REDIRURL;
    set obj.status = 301;
    unset req.http.X-REDIRURL;
    return(deliver);
}

 

I hope I clarified the issue.

 

Thanks

Puneet

Hello, Puneet. You'll need to do the blocking on the sub vcl_recv and not
sub vcl_error.

 

Here's an easy VCL config example:

 

acl forbidden {
  "xxx.xxx.xxx.xxx";
  "xxx.xxx.xxx.xxx";
}

sub vcl_recv {
  # Prevent access from these hosts
  if (client.ip ~ forbidden) {
    error 403 "Forbidden";
  }
}


Let me know if you have any other questions.

Hi all,


I want to stop the users accessing my website via IP address.
I am using varnish as cache.
I have the following code in place but it is not working.

In vcl_recv() {
     if(req.url ~ "XX.XX.XXX.XXX") {
     error 750 "Moved Permanently";
  } } 

And in vcl_error()
sub vcl_error {
    if (obj.status == 750) {
    set req.http.X-REDIRURL = regsub(req.url,"https?://[^/$]+", "
<http://www.linkedin.com/redirect?url=http%3A%2F%2Fmywebsite%2Ecom&urlhash=5
qRF&_t=tracking_anet> http://mywebsite.com");
    set obj.http.Location = req.http.X-REDIRURL;
    set obj.status = 301;
    unset req.http.X-REDIRURL;
    return(deliver);
}

But this does not redirect the user to the website, instead it delivers the
page.
Can anyone tell what I am missing?

 

Thanks

Puneet
