It seems that you have correctly configured the network emulator tool by setting the upstream bandwidth and adding a filter for the desired remote IP. However, if your YouTube video is also experiencing disruption, it suggests that the network emulation may be impacting other connections as well. To ensure that only the network between the remote IP and your local is affected, you may need to recheck your settings and ensure that they are accurately configured. Additionally, you may consider reaching out to the support or documentation for the network emulator tool for further assistance.
