I have a server with two NICS: one is connected to the dmz and the other is connected to the internal LAN.
Now I want to use the adito software (open-source version of SSLExplorer) to create a vpn-server.
The server runs Ubuntu version 8.10 OS, and I wonder how I should set it up to achieve my goal.
The dmz and the internal LAN are already protected by a firewall system.
My final aim is that users will be able to connect to the NIC on the dmz, authenticate, and then get access to the internal LAN.
Q1: Do I have to install some form of firewall to maintain security, or could this be taken care of by the adito software ?
Q2: Which packages do I have to install on the Ubuntu box?
Q3: Any other things I should be aware of?
