Setup network for internet access

If the VPN-X server is run behind a (A)DSL modem/route or other route, you should configure the (A)DSL modem/router and setup "Port Mapping / Port Forwarding”.

Gather the VPN-X Server local information

• By default, VPN-X listens on 25000 UDP/TCP, and 25443 TCP(SSL/TLS). 
  

If your VPN-X server is behind a router, you need to get real local/LAN IP address of VPN-X server machine. Because port-forwarding need this information.

• Please see “Local Area Connection” properties

• Select “Internet Protocol (TCP/IP)”

• Click the “Properties” button

• Remember these settings in your mind. We recommend you write them down.

For the professional user, you can use Windows commands, Linux or FreeBSD or Mac OS X commands.
Windows command: ipconfig /all
Linux/BSD/OSX command: ifconfig

Firewall settings

VPN-X can help you set Windows built-in firewall automatically. If you are using a third-party firewall, we recommend reading this section first then read the third-party user manual. Almost all firewall has the same mechanism.
Windows XP or above versions have a built-in firewall.  You should let the VPN-X listening ports be excluded, so an outside user can access the VPN-X server

running on Windows. For other platforms, there may be other firewalls as well, so you should check the firewall setting on your OS platform.

• Click the “Windows Firewall” to manage the security settings.

• Click “Add Port…” to add VPN-X listening ports.

Port Mapping/Forwarding

Each type of (A)DSL modem has a different operation/administration webpage. Please read your (A)DSL modem manual for more information.
If you can’t understand the port forwarding or port mapping, here are some references:

• http://en.wikipedia.org/wiki/Port_forwarding
• http://www.portforward.com/help/pfprogression.htm

Maybe you can find your route in this list: http://portforward.com/routers.htm

In this manual, we will use SMC (A)DSL modem to explain how to configure port mapping.

Open page: “NAT->Virtual Server”.

Set DNS or DDNS for your public IP.

This manual just gives a brief way to setup your own DNS or DDNS.
If you have a static public IP address, you can setup DNS for the IP. If the public IP address is dynamic, you should setup DDNS, and install DDNS client for updating the public IP.
If you don’t have the DNS or DDNS, the client can only use the long, hard to remember public IP address to access the VPN-X server. It’s just inconvenient, and not a fatal problem to setup a VPN.
