        - What IP address scheme should my 2Wire Home Portal use?

greetings,

>>My ISP uses following IP Address Scheme:
>>172.16.0.0/255.255.0.0
first of all make sure that the ISP has given you a public static ip for your use. the above addresses are internal afik and cannot be accessed over intranet.

to setup VPN, your vpn server should be publically accessible over internet to my best knowledge.

Pasting a response to Static IP Address Question from my ISP's website:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>
How do I configure my network device for a static IP address?

The 2Wire HomePortal supports both Dynamic and Static IP addressing on your HomePortal network. The HomePortal is a DHCP server and will automatically assign an IP address to a network device upon request. However, you can manually configure a static IP address for any device on your HomePortal network.

The first 32 addresses (.1 - .32) in the address range are allocated to static IP addresses. The next 218 addresses (.33 - .250) are allocated to the HomePortal’s DHCP server to deliver to dynamic clients. The last 4 addresses are reserved (.251 - .254).

Below are the settings for the three home network IP range options offered by the HomePortal :

Default Settings:
Static: 172.16.1.1 - .32
Dynamic: 172.16.1.33 - .250
Reserved: 172.16.1.251-.254
Subnet: 255.255.0.0
Default Gateway: 172.16.0.1
DNS: 172.16.0.1
      

Option 1:
Static: 192.168.1.1 - .32
Dynamic: 192.168.1.33 - .250
Reserved: 192.168.1.251-.254
Subnet: 255.255.0.0
Default Gateway: 192.168.0.1
DNS: 192.168.0.1
      

Option 2:
Static: 10.0.1.1 - .32
Dynamic: 10.0.1.33 - .250
Reserved: 10.0.1.251-.254
Subnet: 255.255.0.0
Default Gateway: 10.0.0.1
DNS: 10.0.0.1

Go to http://www.whatismyip.com/ to find out what your public IP address is.  This is the address that your VPN clients will connect to.

I tried different IP address configurations, and finally  got it working with the following set up:

2Wire Home Portal Configuration:  
     IP Address range:  172.16.0.2 - 172.16.0.254
     Subnet Mask:        255.255.255.0
     DNS server:          172.16.0.1
     default gateway:   172.16.0.1
     DHCP:                   Enabled

WAN Network Adapter
     IP Address:          Static address within the range  172.16.0.2 - 172.16.0.254

LAN Adapter
     IP Address:          Static address - 192.168.0.x
     Subnet Mask:       255.255.255.0
     No default Gateway
 
VPN Server Set up:
      DHCP:  Enabled, IP Address range 192.168.0.x to 192.168.0.y
     
Wow! I did learn some networking!
