I would like to control which ports BOINC uses so my router can prioritize by port sets. For example, I would set the QoS in the router for ports 54300-54400 for low priority, and have BOINC only use these ports for upload and download. Is this a BOINC issue, or a firewall issue? Thank you for the help.

For internet, BOINC uses by default ports TCP80 and TCP443.
To communicate between its parts, BOINC uses TCP31416 on the localhost machine only (address 127.0.0.1).

Since you don't have to set in a router which ports BOINC uses for localhost operations, the only ones you would set it for communications. But is default 80 and 443 really a nono? The only way around those values is the use of a proxy.
