Deny all, allow only one IP through htaccess
.Htaccess.Htaccess Problem Overview
I'm trying to deny all and allow only for a single IP. But, I would like to have the following htaccess working for that single IP. I'm not finding a way to have both working: the deny all and allow only one, plus the following options:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin
ErrorDocument 404 /index.php
</IfModule>
Is there a way to make this work?
.Htaccess Solutions
Solution 1 - .Htaccess
order deny,allow
deny from all
allow from <your ip>
Solution 2 - .Htaccess
I know this question already has an accepted answer, but the Apache documentation says:
> The Allow, Deny, and Order directives, provided by mod_access_compat, > are deprecated and will go away in a future version. You should avoid > using them, and avoid outdated tutorials recommending their use.
So, a more future-proof answer would be:
<RequireAll>
Require ip xx.xx.xx.xx yy.yy.yy.yy
</RequireAll>
Hopefully, I've helped prevent this page from becoming one of those "outdated tutorials". :)
Solution 3 - .Htaccess
This can be improved by using the directive designed for that task.
ErrorDocument 403 /specific_page.html
Order Allow,Deny
Allow from 111.222.333.444
Where 111.222.333.444 is your static IP address.
When using the "Order Allow,Deny" directive the requests must match either Allow or Deny, if neither is met, the request is denied.
http://httpd.apache.org/docs/2.2/mod/mod_authz_host.html#order
Solution 4 - .Htaccess
Slightly modified version of the above, including a custom page to be displayed to those who get denied access:
ErrorDocument 403 /specific_page.html
order deny,allow
deny from all
allow from 111.222.333.444
...and that way those requests not coming from 111.222.333.444 will see specific_page.html
(posting this as comment looked terrible because new lines get lost)
Solution 5 - .Htaccess
Improving a bit more the previous answers, a maintenance page can be shown to your users while you perform changes to the site:
ErrorDocument 403 /maintenance.html
Order Allow,Deny
Allow from #.#.#.#
Where:
#.#.#.#
is your IP: What Is My IP Address?- For
maintenance.html
there is a nice example here: Simple Maintenance Page
Solution 6 - .Htaccess
Just in addition to @David Brown´s answer, if you want to block an IP, you must first allow all then block the IPs as such:
<RequireAll>
Require all granted
Require not ip 10.0.0.0/255.0.0.0
Require not ip 172.16.0.0/12
Require not ip 192.168
</RequireAll>
- First line allows all
- Second line blocks from
10.0.0.0
to10.255.255.255
- Third line blocks from
172.16.0.0
to172.31.255.255
- Fourth line blocks from
192.168.0.0
to192.168.255.255
You may use any of the notations mentioned above to suit your CIDR needs.
Solution 7 - .Htaccess
Add the following command in .htaccess file. And place that file in your htdocs folder.
Order Deny,Allow
Deny from all
Allow from <your ip>
Allow from <another ip>
Solution 8 - .Htaccess
I wasn't able to use the 403 method because I wanted the maintenance page and page images in a sub folder on my server, so used the following approach to redirect to a 'maintenance page' for everyone but a single IP*
RewriteEngine on
RewriteCond %{REMOTE_ADDR} !**.**.**.*
RewriteRule !^maintenance/ http://www.website.co.uk/maintenance/ [R=302,L]
Solution 9 - .Htaccess
You can use the following in htaccess to allow and deny access to your site :
SetEnvIf remote_addr ^1\.2\3\.4\.5$ allowedip=1
Order deny,allow
deny from all
allow from env=allowedip
We first set an env variable allowedip if the client ip address matches the pattern, if the pattern matches then env variable allowedip is assigned the value 1 .
In the next step, we use Allow,deny directives to allow and deny access to the site. Order deny,allow
represents the order of deny
and allow
. deny from all
this line tells the server to deny everyone. the last line allow from env=allowedip
allows access to a single ip address we set the env variable for.
Replace 1\.2\.3\.4\.5
with your allowed ip address.

Solution 10 - .Htaccess
You can have more than one IP or even some other kind of allow like user, hostname, ... more info here https://www.askapache.com/htaccess/setenvif/
SetEnvIf remote_addr ^123.123.123.1$ allowedip=1
SetEnvIf remote_addr ^123.123.123.2$ allowedip=1
SetEnvIf remote_addr ^123.123.123.3$ allowedip=1
SetEnvIf remote_addr ^123.123.123.4$ allowedip=1
Order deny,allow
deny from all
allow from env=allowedip
Solution 11 - .Htaccess
ErrorDocument 403 /maintenance.html
Order Allow,Deny
Allow from #:#:#:#:#:#
For me, this seems to work (Using IPv6 rather than IPv4) I don't know if this is different for some websites but for mine this works.
Solution 12 - .Htaccess
order deny,allow
deny from all
allow from set your IP
Solution 13 - .Htaccess
If you want to use mod_rewrite for access control you can use condition like user agent, http referrer, remote addr etc.
Example
RewriteCond %{REMOTE_ADDR} !=*.*.*.* #you ip address
RewriteRule ^$ - [F]
