[Openswan Users] A quick question

[ihsanturkmen at hedefalliance.com.tr]

Hi..
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.

If you need to make a host-to-host VPN, you don't need two network 
interfaces.

[Openswan Users] A quick question






Hello everyone,

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? 

 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?

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? 

Thank you.
