We setup the VPN gateway in our company FW to allow remote office to access our internal web server and the VPN dns server we are configure to use our internal DNS .Our company internal domain name is abc.local. During we do our testing in internal office i can access the portal using http://web/portal
but in remote office connected with VPN we must used http://web.abc.local/portal
.Please advice any way to allow external user to use http://web/portal
to access to internal web server.
