You can restrict access to the Web Interface login of your RRPproxy account as well to access via API to listed IP addresses. This way you can make sure only IP addresses you have defined can access your account. Please keep in mind that when using dial-up IP addresses these might change. We don't want you to lock yourself out of your account.
You can set up IPv4 addresses that are allowed to access your RRPproxy account via Web Interface or API. Single IPv4 addresses or ranges from 24-30 are allowed. (e.g. 192.0.2.42 or 192.0.2.42/27)
Important: Internal and reserved IPv4 addresses will not work! Please use your external IPv4 address(es) connecting to our API gateways.
You can find and edit your IP Whitelist settings in the Web Interface of your RRPproxy account via the User menu on the upper right side -> Settings -> Account Data -> Security.
