ISA 550 Bandwidth Management.

Question

I wanted to know an automated or manual method of bandwidth management for ISA 550 with 1.2.x.x firmware. I currently have 30 nodes on a 2mbps link and if one host starts downloading others are left with very little or no bandwidth at all. Is there a way I can regulate this automatically or manually?

Sounds like Ciscomax got you fixed up.  Also wanted to mention, should the need arise, you can do bandwidth throttling.  We do this in some circumstances on Guest Wireless networks to prevent guests from hogging to much bandwidth.  So, for example, if you wanted to limit bandwidth on a GuestWiFi to 512K/128K, you would do the following.
From within the ISA500 Config Utility, select Networking on the left
Expand QoS and select General Settings
Select to Enable WAN QoS and select Save
Expand WAN QoS and select Traffic Selector (Classification)
Select Add
Class Name:                   G-WiFi (In)
Source Address:                        Any
Destination Address:      Guest_Network
Select OK
Select Add (again)
Class Name:                   G-WiFi (Out)
Source Address:                        Guest_Network
Destination Address:      Any
Select OK
Select Save
Select QoS Policy Profile under QoS, WAN QoS in the Networking section on the left
Select Add
Policy Name: G-WiFi (In)
Select the Inbound Traffic radio button
Select Add
Select G-WiFi (In) from the Class drop down menu
DSCP Marking:  None
CoS Marking:     7
Rate-limiting:      512
Select OK
Select OK
Select Add (again)
Policy Name: G-WiFi (Out)
Select the Outbound Traffic radio button
Select Add
Select G-WiFi (Out) from the Class drop down menu
