I'm trying to configure Site-to-Site VPN between Windows Azure and on Premise network using Cyberoam CR25iNG UTM Firewall

The Local Network Subnet is 

192.168.0.1/20 (192.168.0.0 - 192.168.15.255)

The Address Space of Azure is 

192.168.16.0/20 (192.168.16.4 - 192.168.31.254)

The following subnets have been created on Windows Azure

FrontEndSubnet 192.168.18.0/24 (192.168.18.4 - 192.168.18.254)
BackEndSubnet  192.168.20.0/24 (192.168.20.4 - 192.168.20.254)
ADDNSSubnet    192.168.22.0/24 (192.168.22.4 - 192.168.22.254)
Gateway        192.168.16.0/24 (192.168.16.4 - 192.168.16.254)

I've followed the instructions on

http://www.windowsazure.com/en-us/manage/services/networking/cross-premises-connectivity/

I've got a valid Gateway address and managed to generate a Pre-Shared key.

On the Cyberoam gateway, I've setup an IPSEC VPN connection entering the gateway details and configuring the subnets as follows:

Local Network: 192.168.0.0/255.255.255.0

Remote Network: 192.168.16.0/255.255.240.0

Cant manage to connect from the Azure Side or the Local Network.

Azure only has scripts for Cisco, Juniper and Microsoft RRAS.

Anybody managed to use Cyberoam to connect with Azure VPN?
