Routing issues with IPsec (Remote Access)

Hi, 

I am sure this is something that is really easy to fix but I seem to be having some issues with the IPsec (Remote Access) setup. I have followed a detailed setup guide and while I can connect OK, once connected I cannot seem to ping anything on the internal network. I believe I have setup the firewall rules correctly, 

Here are more details:

VPN > IPsec (remote access) :

Assign IP from 10.10.10.10 - 10.10.10.30 (IP Host created for this range called Remote_VPN_Subnet 

DNS Server 1 = 192.168.12.200

Permitted Network - PCL_Subet (192.168.12.X)

Firewall Rule: PCL_Remote_VPN_Access 

Source Zone : VPN

Source Network : Remote_VPN_Subnet 

Destination Zone : PCL_Zone 

Destination Network : PCL_Subnet 

Match Known Users : CHECKED 

Users or Group : PCL_VPN_Users 

Is there another step I am missing? 

Any help would be greatly apprecaited, I am sure I am just missing something small. 

Many thanks, Daniel Hargrove
