Hi ! Sorry for my bad english (I'm French)! At my work, a TL-ER604W is installed after a Netgear (this one is only to take DSL at the TL).
For a remote desk, there is a IPsec tunnel. All is ok.
For employees out on the road, wich need to connect at the enterprise server from customers (Wifi, 3G), I had a PPTP tunnel and configured the VPN connexion on their laptop (Windows 10).
It's ok, they can work on the server from 3G or remote wifi.
But ... they have no more Internet access to use the browser or to read their mails, only by the desk of the server.
I tried by unchecking "Use the default gateway for the remote network" (if the translation is good) in the advanced TCP/IP parameters of the VPN connexion.
Fine ! It's possible to use IE or Chrome or to read the mail during the VPN connexion ... but the server desktop is not accessible any more.

Please, could you help me and say me what I must have to do ?

thanks a lot !!
