DNS Issue with VPN

I'm beginner with fortinet product.
I try to configure my FortiGate 50E.
I configure the vpn. I can connect with FortiClient VPN without problems..

on the Fortigate On dns I specify my dns server as primary server and the Local Domain Name.
On my remote pc , When I'm connected with the VPN I ping the DNS server with ip adress but not with his name.
if I make a nsloockup MYserver I got this :
nslookup MYserver
Serveur :

*** ne parvient pas à trouver hellboy : Non-existent domain
Did you have an idea ?

You have to specify your VPN DNS at VPN settings. Those are the DNS that vpn users will use when they connect with the client.

looks like your VPN is configured to give an ip and the fortinet system dns as dns. 
Fortinet DNS does of cours not know your local domain.
So you might have to reconfigure that to givinig you one dns that can resolve your local domain.
Keep in mind that the vpn connection will still use the dns you have on client side ( either by dhcp or entered static in he vpn interface set up on client)!
