Here is how to manage unreachable applications on Upsun:
- The problem: Certain internal applications must stay completely isolated from public internet requests.
- The fix: Choose between two main strategies: setting up a public route with restricted access, or configuring no public route at all.
- Why it matters: Understanding these route constraints helps you balance security layers effectively without over-complicating your setup.
