View Full Version : SnapGear SG300 Setup VPN to work with TheGeenBow Client

11-23-09, 04:55 PM

I have got this scenario for one my client as below :

1- Netgear ADSL modem router Dg384 is connected to my ISP, its LAN ip
address is :

2- One of its LAN port is connected to a WAN port (ip address is : of a SnapGear SG300 and LAN ip address for SnapGear SG300

I know that VPN does not like double NAT and I can not convince the
client to get rid of one device and he does like me to bridge the ADSL
router either.


In the link above I was able to configure TheGreenBow VPN Client to
connect to a Netgear router FVS318 V3 (single NAT)

but in my case I do not have Netgear router FVS318, instead I have got
Snap Gear SG300,,,,,,I did my best to configure the IPSec for SnapGear
SG300, but I could not figure out where is my mistake, my confusion
during VPN configuration I have to use many IP addresses, but I was
not sure which one should I choose (be aware there is a double NAT ).

I have posted this question to many forums but I could not be
convinced with answers.

I really appreciate experts comments about this issue ?
