I have a IBM x3400 Server Machine with Windows Server 2008 R2 installed on it. But, since I am not expert on networking I have some problems.

These roles installed on my server:

• Active Directory
• DNS
• File Sharing
• Hyper-V
• ISS
• VPN

There is two network card on them. I configured them like this:

Local Connection 1:

192.168.30.3
255.255.255.0
192.168.30.2

127.0.0.1

Local Connection 2:

192.168.30.101
255.255.255.0
192.168.30.6

127.0.0.1

My problem is, when I use this Ip gateways, It is sharing internet to all computers. This is not I want. I want to use Local Connection 1 for internal network. I am giving all computers gateway and DNS IP as 192.168.30.3

The Local Connection 2 is for Hyper-V and VPN connections.

192.168.30.2 and 192.168.30.6 are my modem's gateways. I am using 192.168.30.6 external IP for VPN connections.

There is two 24 port switches. There is a connection between them and this two ethernet card connected directly to them. And modems are connected to switches as well (Morems are not near the server. They are somewhere in the building).

I disabled network Bridge and removed all ethernet cards from it.

With this configuration, all computers can ping my server's IP (192.168.30.3) but on server I cannot ping any clients (Request timeout).

What is the best way to configure my network?

Thank you.
