There are two ways of traffic.
Inbound and outbound traffic.
Most built in firewalls in cable modems are default setup to block unwanted inbound traffic.
Outbound traffic is mostly handled/monitored by a software firewall.
What is allowed to go from your PC to the internet is defined by firewall rules.
If you install software which needs to contact a server somewhere on the
web, it can only work properly if you tell your firewall that this app is allowed
to setup such connection.
Connections are using an IP address and a portnumber
Example: HTTP traffic (internet browser) use port 80 to setup a connection.
When I install the new UBI game software you most likely will need to adjust
your firewall (or the firewall may create an automatic rule), or UBI uses a
port which is already set open for outbound traffic.
So you are only allowing traffic streams. There is no rule created for the
content of the traffic.
For trying to discover what UBI will send to their servers you need to analyze
these streams with a packet sniffer like WireShark (UBI is aware of packet
sniffers and will surely have their data scrambled).
Unless you are good in deciphering, I don't think we will ever be sure what
UBI will sent to their servers.
