LAN to LAN using IPSec |
|
|
Hello all,
IS I have 2 vpn "concetrators" at 2 remote locations I can create an
IPSec "tunnel" right? If I can and do this "tunnel" will the clients on
one LAN be able to communicate with the clients on the other? Assuming my
routes are good and im NAT'ed ok.
I dont get the difference between PPTP and IPSec. Other than the
encrtyption aspect. I can get pptp running no problem and I "get it"
but how's IPSec different?
thank you for your time and knowledge!

The normal way to connect 2 LANs is to use a VPN box (firewall,
router, concentrator etc.) at each end. Once they're configured
correctly, all traffic between the two locations goes through a VPN
tunnel between the two VPN boxes. Client computers are totally
oblivious to the fact that the communication was encrypted on the way.

VPN is a generic term for encrypting and authenticating traffic in a
public network. There are several competing protocols (actually
collections of protocols) for implementing a VPN; PPTP is one, IPSec
is another. For example, PPTP uses one method for key exchange, IPSec
uses another. I'm not familiar with PPTP, but I can say that IPSec is
notoriously complicated.
Hope this helps.

For the most part, yes. However, some protocols are non-routable,
especially if they rely on broadcast traffic, which normally isn't
sent through the tunnels. It depends on what your trying to do.

they use different ports and ipsec is stronger and has more encryption
options. use ipsec if possible.
