here!</P>
<P style="MARGIN-BOTTOM: 0cm"><rpc> it's AH, not AHA and stands for
Authentication Header</P>
<P style="MARGIN-BOTTOM: 0cm"><rpc> the E in ESP stands for
Encapsulating</P>
<P style="MARGIN-BOTTOM: 0cm"><th0rn> so... i'm confused... when u
mentioned how old packets are encrypted in the data portion of new packets sent,
wouldn't that only apply when the nodes sending/receiving data over the VPN were
in the middle of a 3 way handshake? (plz don't flame cuz i'm fairly new) But
isn't that the only time one node would have to send an OLD packet (at the same
time with the new packet) to the other (which would be a syn(old packet) and
ack(new packet)?</P>
<P style="MARGIN-BOTTOM: 0cm"><c0ld> PPTP is for Linux</P>

<P style="MARGIN-BOTTOM: 0cm"><_Jonah_> shit</P>
<P style="MARGIN-BOTTOM: 0cm"><bloppy-ph33r> :/</P>
<P style="MARGIN-BOTTOM: 0cm"><_Jonah_> PPTP&L2F make up L2TP</P>
<P style="MARGIN-BOTTOM: 0cm"><c0ld> oh nevermind, there is a Linux PPTP
client</P>
<P style="MARGIN-BOTTOM: 0cm"><c0ld> my bad</P>
<P style="MARGIN-BOTTOM: 0cm"><_Jonah_> so L2tp takes the protocol
concepts from PPTP&L2F</P>
<P style="MARGIN-BOTTOM: 0cm"><LiquidCrystalDismay> thank you :)</P>
<P style="MARGIN-BOTTOM: 0cm"><Phaedrus> (where the ESP, of course, holds
the authentication and crypto parameters of the the encrypted bits of the
message)</P>
<P style="MARGIN-BOTTOM: 0cm"><_Jonah_> and it is used in it</P>
<P style="MARGIN-BOTTOM: 0cm"><_Jonah_> i believe i said AHA right</P>
<P style="MARGIN-BOTTOM: 0cm"><_Jonah_> the first time</P>
<P style="MARGIN-BOTTOM: 0cm"><Phaedrus> _Jonah_: As far as packet
construction goes.....is VPN doing the encryption first, or the authentication
first?</P>
<P style="MARGIN-BOTTOM: 0cm"><b0ttyburp> exellent so far carry on... oh
and i word from our sponsors:</P>

<P style="MARGIN-BOTTOM: 0cm"><[PhaLanX]> =P</P>
<P style="MARGIN-BOTTOM: 0cm"><th0rn> wait, so is the encryption of older
packets only implemented during the middle of a 3 way handshake? i'm
confused</P>
<P style="MARGIN-BOTTOM: 0cm"><b0ttyburp> :O)</P>
<P style="MARGIN-BOTTOM: 0cm"><th0rn> or is this used more often than i
realize....</P>
<P style="MARGIN-BOTTOM: 0cm"><rpc> there's also another subsystem of
