<br><font size=2 face="sans-serif">There are two VPN types. One is transport
mode (host-to-host) and the other is tunnel mode (network-to-network) .
If you want to make a network-to-network VPN , you need two network
interfaces on each side , one for external network and the other
for the internal network.Interfaces do not have to be ethernet, any other
type of interface wellcomes. .,You don't have to have a public ip address
either . It is not a must.</font>
<br>
<br><font size=2 face="sans-serif">If you need to make a host-to-host VPN,
you don't need two network interfaces.</font>

<br><font size=3>Hello everyone,<br>
<br>
I was reading a book called "Network Administrators Survival Guide"
by Cisco Press. Over there, at the chapter "Linux based VPN",
it says that the Linux machine that holds the Openswan VPN Server should
have a 2 Ethernet NIC cards. One for publicly routed IP address and for
the private network. Is this correct? <br>
<br>
I have a computer in my private network and it has one NIC card. This
machine is a Linux machine, behind a firewall router and has Openswan 2.4.5.
So, can't I use this Linux machine as a VPN Server?<br>
<br>
One other question is that when I make a host-to-server connection from
remote, What IP address the remote host will take? Is there supposed to
be a DHCP server in the private network where the Openswan Server resides,
or perhaps in the machine that holds Openswan VPN server? <br>
<br>
Thank you.<br>
<br>
