Hello @Anonymous ,
I understand that you are routing your web traffic requests to the nearest geographic endpoint using Traffic manager Geographic routing but would like to restrict the access to your application by a specific region.
Directing traffic to a specific region can be achieved by configuring Geographic routing method in Traffic Manager.
But if you want to restrict the access to your application by a specific region, I would advise to go with Geo-filtering option in Azure Front Door.
By default, Azure Front Door will respond to all user requests regardless of the location where the request is coming from. In some scenarios, you may want to restrict the access to your web application by countries/regions. The Web application firewall (WAF) service in Front Door enables you to define a policy using custom access rules for a specific path on your endpoint to either allow or block access from specified countries/regions.
