The client opens ports 80 and 443 outbound when it uploads and downloads work units. Port 443 is to the work unit servers (using HTTPS) and 80 is to your member homepage to update your stats. These ports are only open for a brief amount of time during the upload/download phase.

If you are concerned with security Zone Alarm offers a nice, free fire wall. The client works fine behind firewalls and routers. Just give access to the Program Files/United Devices/(specifically; cs.ud, ud_######.exe and ud.exe) and the Windows/System/ (specifically; UDwin_1701_2428.dll) directories for the client to work properly behind a firewall. Visit the Security forum for more details on security.
