This is my system, they're all VMs (except the internet router) as I'm using VMWare for this

Remote User (Bridged) ---- Router ---- WAN port (Bridged) ---- LAN port (internal network) ---- internal system (internal network)

Here are what I've done

*SSL VPN Group


*SSL VPN User


*LAN IP host


*SSL VPN Ip host


*SSL VPN Settings


*Firewall Rule
