To limit your application access by IP address, all you have to do is define the 'internal network' - the range of IP addresses allowed to access the most sensitive applications. Here's how it works: you submit a request to OutSystems support to set or re-configure the 'internal network', and then use the OutSystems developer environment to mark applications for 'internal access only'. This way, OutSystems console applications - Service Center, LifeTime, and Service Studio - become 'internal access only'.
