Calculating bandwidth

I have a student network on dmz side of the firewall and staff on the lan side that access terminal services over a site to site VPN. Both networks run fine but on specific days the students network spike considerably and the staff side is killed. This would appear to be down to streaming. I have increased the size of the firewall but I am unsure of the broadband speed and if I should increase it as I presume the students will simply eat up the increased bandwidth.
Can anyone with solid experience in this area advise how they size. I tried using QOS on the Checkpoint and the whole network on both sides screamed to a halt so I rolled back. The checkpoint technician advising me didn't seem very sure.

You can use QoS or policy maps to limit bandwidth.

I use Cisco ASA firewalls so I can't give you configuration details on Checkpoint firewalls but the concepts are the same. Go over your QoS settings again, you may have missed something or blocked too much to cause traffic to halt.

All the best

See if your firewall supports netflow, SNMP, and/or a top talkers report.  These will help you identify the source of the network congestion.  You can then craft a QOS config for that specific type of traffic.
