setting up pptp and l2tp

We were just talking about this in my Networking Theory class. PPTP and L2TP are two different protocols, either of which could be used for a VPN. I was given to understand that you used one or the other, but not both at the same time.

i see, but will i be able to open both listening port? or 1 at a time? will it cause conflict?

 

[Packet]

you can allow traffic (read: open listening ports) for both L2TP and PPTP.

off the top of my head, you need:
TCP 1723
Protocol 47

UDP 1701
UDP 500


PS: You may well need Protocol 50 (for IPSec ESP)

I see..Thank you very much

If you set up the VPN using the default GUI all those ports would be automatically opened up for you. There is no reason to set up a VPN manually, the built in GUI works perfectly and is by far the easiest way.

A quick question, when i setup the vpn l2tp/pptp/ipsec to my home from my office, will it consume the bandwidth in my office?

 

[Packet]

?
you will use outgoing bandwidth, yes. if that's what you mean

 

[cashng]

yes, outgoing, will it take up a lot of bandwidth??

 

[cashng]

how do i enable multi connection for vpn

 

[Packet]

as goes outgoing bandwidth, it depends how much traffic you use.
by itself, the header / encapsulation / padding isnt much - but if you're now going to start say downloading huge files off your vpn connection, then yes, it'll take up a fair amount.

what do you mean by multi connection?

 

[cashng]

i mean 2 users connect to the same vpn at 1 time. I just figure it out, only 1 connection is allowed at 1 time, as the OS that i am connecting to is windows, its not server. Correct me if I am wrong.

 

[Packet]

if the OS of the vpn server is windows 7, you're limited to 1 connection.
