2. MSN Messenger.
a) See 1.
3. Where are you setting the policies? Policies can be done many ways, here is a suggestion:
a) Create your 3 groups. Add your users into the specific groups
b) Navigate to the WWW Proxy Service
c) In the General page, select your authentication method.
d) On the Policy Page, Set the Default Rights to "are ignored"
e) Click the Add Button
f) Select group called "Low" and set the radio button to "Users must be authenticated"
g) Go to the Advanced tab, Add Filter, Add Criterion
h) This Criterion is NOT met if HTTP URL Contains Hotmail
i) Add another website to block; Add Filter, Add Criterion
j) This Criterion is NOT met if HTTP URL Contains Yahoo
k) OK back to the WWW Proxy Service Properties.
l) Go back to e) and do the restrictions for the MED users
m) Go back to e) and set a policy for the HIGH users; if they have full access, then you will only need to specify an authentication method.
4. Not sure, try WinGate 6.1
5. Please detail your question better; but it sounds like you just need to Doubles Click the Service, and change the port number.
