Hello all,
I recently had to do port forwarding on a router, to get a device to communicate properly with external traffic.
A weird thing happened though, immediately after saving the changes in the router, I couldn't communicate with the device through the external IP (even though "canyouseeme.org" showed an open port).
About an hour later I tried again, and the device was communicating correctly.
This is the first time I've had to do this, so I was wondering if it was normal for changes to take time to take effect (maybe under specific circumstances)?
Thanks for any information!
