TIPS
The connection is lost after a few
minutes:
System-based characteristic of the
UPnP standard. Useful communication
starts at a port numbered above 1024
and changes this regularly during
operation. Not all firewall programs
recognise this knocking on different
doors as a continuous connection.
Depending on the configuration, the
firewall decides, in a case of doubt,
against an unknown client.
Depending on the firewall software, this
can be resolved through the following
actions:
•
By using a fixed IP and without DHCP,
define the Symphony
as a so-called
Trusted Host, i.e. a device from which
all communication is considered to be
trustworthy.
•
Allow the server to accept incoming
and outgoing communication with the
Symphony
over ports 1024 - 65535.
Activate the exception setting for "UPnP
Framework", e.g. Windows XP Firewall or
activate "Permit UPnP communication".
