I cannot edit the internal IP address to Public IP address as the instruction is not clear.
I try to edit the link in many way but the address I enter is incorrect and I can never download the file.
Can you give more specific instruction?
The purpose of step 4 is to view the object as if you were a customer. When running the lab you should see an IP that references the swift object from the IP path of the node using internal IP. If you were to use the same long URL, but replace the internal IP with an external IP it should still work.
What IP do you have prior to the edit, is it a 172.24.xx.yy?
