Open SSL VPN - Access local server - Wrong IP

Question

Hi guys, 
 I'm new in configurating XG Firewall. I use the XG85W. 
 
 I've configured Open SSL VPN based on the tutorial https://community.sophos.com/products/xg-firewall/p/vpnremoteaccess. 
 I can connect via VPN, but I get an IP 10.20.6.X, which I've set in VPN Settings, and don't reach my internal resources, which based on 10.20.5.X. 
 My #Port 1 LAN is configured to 10.20.5.1/255.255.255.0 
 If I want to assig the IPv4 Lease Range to 10.20.5.100 - 10.20.5.120 under VPN => "Show VPN Settings" the firewall disallow and throws "Network with the same IP address as start lease IP already exits choose diferent IP address". 
 How can I reach my internal network to access Servers? What I'm doing wrong? 
 Regards 
 Marco

H ello Marco, 
 
 You need to set VPN DHCP lease different from your LAN interface in you SSL VPN settings. 
 Then go to VPN > SSL VPN(REMOTE ACCESS) and create a remote access policy and select all SSL VPN users under identity. Create a network firewall Rule as following. 
 
 Src Zone: VPN, Src Network: Any, Dst Zone: LAN, Dst Network: Any, Service: Any, Match Identity: Untick

I found the how to video inadequate in explaining how to setup SSL VPN for remote access so I wrote my own guide which you can find here: 
 Did you create an IP Host for your local subnet and add that to your SSL VPN permitted network resources? The system created IP Hosts that are created (i.e. #Port1 ) are setup for the interface/port IP address and not the local subnet. 
 I also created another IP Host for the VPN IP range such that I can limit the scope of IP addresses the VPN firewall rule applies to.
