Opening your network firewall for Retrospect

Resources

Retrospect uses a well-known port, 497, assigned by the Internet Assigned Number Authority (IANA), for both TCP and UDP. Retrospect also uses subnet broadcast and Multicast packets.

You should configure your firewall to allow Port 497 for UPD and TCP packets.

Users of Windows 2003 SP1 may also need to open firewall exceptions.
