i've been receiving quite a big number of fraudulent orders from the asian region and russia. Since these countries are not the ones i'm targeting, i'd like to lock a store access for them. any quick way to do that?
You may use this free Magento extension - http://www.mageworx.com/geo-lock-magento-extension.html
It will help you get more protection from fraudulent activity in your store by defining the lists of 'denied' or 'allowed' countries, set IP black/white lists and more.
Hope it helps.
Use FME GeoIP Ultimate Lock Extension to block traffic from different countries & Regions. This Extension uses Maxmind GeoIP Country Database which lets you select the desired country or region to block. You can block access to entire store, selected products, or CMS pages.
Zones Manager allows to create zones, restrict a product by zone or restrict a zone by product categories / subcategories and redirect unwanted customers away from your website. There are some other useful features such as fixed prices per zone, restrict a zone store views, restrict a zone by shipping methods, restrict a zone by payment methods and others. It's commercial, though.
This GeoIP Redirect extension will help you to achieve what you need. Just create a CMS page and add a redirect to it for the users coming from the countries you need to exclude. You can set this redirect via the Country to URL Redirect block in the extension settings.
Also you can try out our GeoIP Store & Currency Switcher! https://www.magentocommerce.com/magento-connect/geoip-store-switcher-1-1.html The extension uses GeoIP MaxMind's database and blocks unwanted visitors by IP or Country. But the main aim of this module is switcning Store, Language, Currency and Tax. However if you work internationally this features will be very useful for your busines.
