I think I read somewhere that you have to load up a game (or was it Xbox Live?) for port 21 to appear open. Not sure if it allows FTP access though.
Test 1: Not Signed into Xbox Live at Dashboard --- open ports: 25 (smtp), 110 (pop3), 1030 (?)
Test 2: Signed Into Xbox Live at Dashboard --- open ports: 25 (smtp), 110 (pop3), 1030 (?)
Test 3: PGR 3 in Xbox Live Match --- open ports: 25 (smtp), 110 (pop3)
Test 4: PGR 3 at Main Menu --- open ports: 25 (smtp), 110 (pop3)
Test 5: Watching TV using Media Center on 360 --- open ports: 25 (smtp), 110 (pop3), 35091 (?)
Telneting into any of these ports actually works, although the ports 25+110 present a blank, black window and port 35091 presents 2 symbols upon login. The port 1030 on the dashboard changes. When I ran the scan again, it gave me 1046, running it once more after rebooting gave me 1026. So, that one seems to be a wildcard. I take it that the two static ports are used to send messages and notifications from Xbox Live.

you guys that are scanning... just curious to what apps you are using?? sounds like the run of the mill port scanners, etc... you know when you connect to your pc for streaming it gives you a key to enter in the media connect or the media center software... has anyone ran something like Cain while setting up a connection and then maybe after when streaming and see if something similar to that key is passed???
The key I think is only necessary to allow the Xbox 360 to connect to your PC. I think it serves little more than a login, which I will monitor network traffic for to see. For port scanning, I am using a freeware utility called
LAN Scanner.
Monitoring the network traffic as the Xbox 360 attempts to connect to a PC is interesting. It produced ~126,000 lines of hex in about 25 seconds. The ones of particular interest occur right at the beginning:
