Hi,
@ Chetan
On the GUP, i have: virus & spyware protection, threat proactive protection and network threat protection
On the SEP, it's the same thing.
My SEP machines are Windows 2012 64 bits, Windows Vista Pro 32 bits, Windows 7 Pro 64bits.
No other third party software.
I have tried to change the port but it have'nt solve the problem.
@James 007
No GUP and SEP client are in two differents group so i can use 2 two live update policies.
@Greg12
The rule which block the traffic is "Block and log any other ip traffic".
The GUP is in "Server control"
I don't understand because i have only one firewall rule in the SEPM. This rule has been created by the installation and isn't used on any clients, cf screenshot.
