Cant see internal network

[jasonzook]

Hi,
I'm pretty new to routing and VPN so I appologise if this is a stupid question. I am having trouble seeing machines on my internal network when connected to my VPN. Here is my setup...

My UT box is sitting between my modem and a switch. It is in router mode. The external IP is dynamic, and the internal IP is static (192.168.2.1). My switch has the following settings:

External IP (Static) - 192.168.2.2
Subnet - 255.255.255.0
Default Gateway - 192.168.2.1
DNS - 192.168.2.1
-----
Internal IP (Static) - 192.168.3.1
Subnet - 255.255.255.0
-----
DHCP Server = Enabled
Address Range: 192.168.3.100 - 192.168.3.149


My OpenVPN settings are:
Status - VPN Server
Client Address Pool IP - 172.16.16.0/255.255.255.0
Export DNS = True
Server Port = 1194
DNS Override = False
Exported Networks/Hosts: Internal Network (192.168.2.1/255.255.255.0)

Problem Description:
I can successfully connect to the VPN, and I am able to ping the Internal NIC on my UT box. I can also successfully ping the external IP on my switch (192.168.2.2). I can NOT ping the internal IP on my switch though (192.168.3.1) or anything past that. I have a feeling that I need to add a static route somewhere, but I'm not sure where. I am also not able to ping from inside the network to a machine on the VPN.

I hope I gave enough information. Any help or pointers would be great.
I have also checked and made sure that there are no firewalls blocking any traffic.

Thanks

you should get rid of the double NAT if possible - does Untangle know that .3.0/24 is behind .2.2?

Oh I didn't realize I was double NAT'ing. What would you suggest?
When I first read your post the untangle box did not know about the 3.0/24 network was behind .2.2. I tried adding a static route on the untangle box:
Destination: 192.168.3.0/24
Gateway: 192.168.2.2
And I still have issues. Did I set up the route wrong?
