Hi

Many rules that I distribute via epo are skipped by the firewall on the desktops???

example:
-I created following 2 rules (in epo console):

Rule 1:
  • -Description:Allow Web Outgoing
    -Action:permit
    -Protocol:TCP
    -Direction:Outgoing
    -Application:OUTLOOK.EXE (Match: That Path always and not the fingerprint) Drive: Any Path:Any
    -Local Service(s):Range 1024 - 65535
    -Remote Service(s):List 80, 443, 135
    -Address: Any
    -Log matching traffic: Enabled
    -Active: Enabled

Rule 2:
  • -Description:Block ALL Other Outlook traffic
    -Action:Block
    -Protocol:All IP Protocols
    -Direction:Either
    -Application:OUTLOOK.EXE (Match: That Path always and not the fingerprint) Drive: Any Path:Any
    -Local Service(s):-
    -Remote Service(s):-
    -Address: Any
    -Log matching traffic: Enabled
    -Active: Enabled

-I distribute both rules (that goes all fine)
-Then I start Outlook on a client and chack the logs of the firewall with following conclusions:
  • -Rule 1 works fine
    -Rule 2 is totally ignored???


-What I did then to monitor the problem (on the client side):

1) -I duplicate rule 2 (I call it "Rule 3")
-Then I edit the Application of the rule (because I can't select the "Match" (rule handling) of a local created rule)
so the rule becomes:

Rule 3:
  • -Description:Block ALL Other Outlook traffic (local rule)
    -Action:Block
    -Protocol:All IP Protocols
    -Direction:Either
    -Application:C:\Program Files\Microsoft Office\OFFICE11\OUTLOOK.EXE
    -Local Service(s):-
    -Remote Service(s):-
    -Address: Any
    -Log matching traffic: Enabled
    -Active: Enabled

-Then I start Outlook on a client and chack the logs of the firewall with following conclusions:
  • -Rule 1 works fine
    -Rule 2 is totally ignored???
    -Rule 3 works fine ??? (Why is the identical rule 2 skipped?)

2) -Then I changed the sequence of the 2 rules on the eposerver (rule2 followed by rule1) and distributed it
so the sequence now is:
  • -Rule 2
    -Rule 1
    -Rule 3
  • -guess what: Rule 2 works 100% OK

So my conclusion till now is that I CAN'T trust this firewall because it skips (critical) rules.



I'm using:
-Eposerver 3.5 (+patch5)
-MDF 8.5 + patch 4


Some other dissapointing topics are that:
-MDF 8.5 patch 4 doesn't get distributed via epo???
-When I install MDF 8.5 patch 4 locally via the setup, the About still shows the old build nr 260 instead of 428
but when I check the build version of the files "McAfeeFire.exe", "FireSvc.exe" & "FireTray.exe" in the properties it shows the correct 428


Anyone noticed same strange behaviours?
Or better, has any solutions?


I'm testing MDF 8.5 for a few weeks now.
I started very optimistic but the more I test it the more disapointed I get.


regards
Dave
