Hello,
I wonder whether IPsec combined with L2TP has more
advantage over IPSec alone:
Dial-up User <===(1)======>RAS based on Radius(provided by ISP)
Dial-up User <====(2)=====>IPSec GateWay to companyA's Premise
(1): Dial-up User establishes InternetConnection using ISP
(2): Using IPSec remote Client(on Windows), the user exhanges data(TCP/IP, NetBios) with some host within companyA's Premise protected by IPSec GateWay.
In above case, do we need to use L2TP additionally for intensifying security?
If so , can you tell me details?
