If you expand your ISA array, expand Network Configuration and select Routing you will see a "Default rule". If you right click on the default rule and select Properties and select the Action tab you will see 'Automatically dial out' but none of your entries are shown.

You first need to run a VBS script which is in the \sdk\samples\admin\scripts folder of the ISA CD called Add_DOD.vbs however you will need to edit it first.

Set ISA = CreateObject("FPC.Root")
ISA.Refresh
Set Arrays = ISA.Arrays

arrayname = InputBox("Please enter the array name, or for the first array:")

If arrayname = "" Then
Set arr = Arrays(1)

MsgBox "The array specified array was not found"

'Add Dialup Entry
Set objDialupEntry = Arr.PolicyElements.DialupEntries.Add ("ISA_DISPLAY", "RAS_ENTRY")
'Set the Dialup entry credentials
objDialupEntry.Credentials.UserName = "UserName" 'Enter here your username
objDialupEntry.Credentials.Password = "Password" 'Enter here your password
objDialupEntry.AuthenticationEnabled = True
Arr.Save

Arr.Refresh

'Select routing rule and set the Autodial to the added Dialup Entry
Set objRoutingRule= arr.NetworkConfiguration.RoutingRules(1)
objRoutingRule.PrimaryRoute.AutoDialOut.SetAutoDial True,"ISA_DISPLAY"
objRoutingRule.Save

MsgBox "Done"
End Sub

SetDialupEntry

You need to change the items in Purple. The first, ISA_DISPLAY should be the display name as it should be displayed in ISA, the next is the actual RAS entry name. Set the correct connection username and password. Finally set the autodialout to the dialout entry name.

Now double click the VBS file, you will be asked for the array (just press Enter).

Once done it should be selected under the Default Rule.

If you have any problems and want to remove the dial up entries run Remove_Unused_DialupEntries.vbs script in the same directory and try again!

How do I disable packet filters for ISA?

This is not advisable, you should define filters for all the traffic you wish to allow however if you want to try something quickly you can just disable the filter as follows:

1. Start the ISA Admin tool (Start - Programs - Microsoft ISA Server - ISA Administration Tool)
2. Expand the Arrays, the specific array, Access Policy
3. Right click IP Packet Filters
4. Select Properties
5. Unselect 'Enable packet filtering'
6. Click OK

To enable again perform the above but in step 5 you would select rather than unselect.
