[Openswan Users] A quick question

Thank you for the quick reply Ihsan, :)
I think it would be better to tell what I want to do.
I have a company network behind a firewall router. We have servers and
employees at different physical locations and sometimes these servers and
employees will need to reach the internal company network.
I want to establish a host-to-network type VPN connection with x509
certificates so that employees and servers can reach the company resources
I have a DHCP Server and different data and file servers in the company
network. I will also have a linux machine in the network (Suse SLES 9 with
SP3 Kernel 2.6.5-7.257.smp - the latest available to the Suse SLES 9 - )
that holds the Openswan. This linux machine is also a CA.
Now, for the test purposes, I built a linux desktop PC with the above
mentioned features and put it in the company LAN. No DHCP Server is set on
this test machine. This PC has just one Ethernet NIC card. I intend to use
this PC as a VPN server for now.
Would it be possible to make a host-to-network connection with this
Can anybody give me a clear direction to do this host-to-network VPN
connection with x509 certificates?
PS: I followed the instructions at Nate
Carlson's<http://www.natecarlson.com/linux/ipsec-x509.php>web page but
I couldn't manage to make the connection. :(
Thank you all
