I recently setup a Pfsense router on XCP-NG, and gave it a healthy amount of resources, 4 threads and 4GB ram from an i7 2600. I don’t have many firewall rules or anything like that yet because it is still fairly brand new. The problem is when family members are using Zoom or Teams they are getting poor connection issues even though they will have 6 ping and 100mbps up and down. Are there certain Pfsense settings I need to tweak to work with these types of applications?
Follow the guide and confirm settings such as Disable TX Checksum Offload
