hi guys, <br />
<br />
We've got two sites at the moment, one on the 10.0.0.0/24 network and the other is on the 10.45.191.0/24 network. There is a site to site VPN. At the 10.45.191.0 end, there is a lockdown with firewalls so unless ports are opened nothing really gets through.<br />
<br />
Servers on both networks are able to ping each other, without any problems. <br />
<br />
We've added printers to the server 2008 on the 10.0.0.0/24 network and through group policy we would like that added to the profiles that log on to a server on the &nbsp;10.45.191.0/24 network. However, it's not happening due to firewall restrictions. <br />
<br />
I know ports have to be opened on the 10.45.191.0 end, but which ports? Is it 161? Is it SMB 445?<br />
<br />
Thanks<br />
Yashy

Which port needs to be opened for this to work?!

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
