How to Forticlient Ipsec VPN connect to WAN network

Hi We are running a FortiGate 60D with FortiOS v5.6.2 using a single WAN-Connection (set of public IPs) and a straight C-Class private LAN. We created 2 Ipsec VPN: Dialup - FortiClient (Windows, Mac OS, Android) (called VPN1) and Dialup - Cisco IPsec Client (called VPN2) with 2 diff pre-shared key and same user-group. They can connected and working fine.

But we've the issue with VPN1 cannot connect to WAN network, only access to LAN network. We running the website abc.com on the server 192.168.100.210 and public this website using WAN IP address. So when connected to VPN1, the user can't access to abc.com but VPN2 can. User using VPN1 can connect to abc.com when this line to hosts file:

 192.168.100.210 abc.com

The interface settings

The Ipv4 policy

So any wrong with our config? Any help and support is appreciated.
