Allow Site Access Only From the Office Wi-Fi IP During Maintenance

Just a memo.

This post summarizes the procedure for putting a site into maintenance.

Procedure

maintenance.html

Place maintenance.html under the DocumentRoot.

Restrict access with .htaccess

ErrorDocument 503 /maintenance.html

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{REQUEST_URI} !^.*\.(js|css|gif|jpg|png|ico)$
  RewriteCond %{REQUEST_URI} !^/cron/.*$
  RewriteCond %{REQUEST_URI} !=/maintenance.html
  # 社内
  RewriteCond %{REMOTE_ADDR} !=<社内Wifi IP>
  RewriteCond %{REMOTE_ADDR} !=<社内Wifi IP>
  RewriteRule ^.*$ - [R=503,L]
</IfModule>

That’s all.
