RE: ADSL + pppoe(rp-pppoe) on LINUX + FREEBSD



Hi

The process of forwarding the tunnel from Bezeq's RedBack to the ISP's
equipment is using a L2TP feature called tunnel forwarding (or something
like that).
L2TP supports 4 such hops.

of course not. the tunnel is meant to bring you to the point where you
are supplied the ip. it is like a regular dial-up. the only difference
is that the tunnel is needed to jump over the various phsyical barriers
which should not be the concern of the user. So, i have two answers. If
the ISP don't have the required hardware then the ip is supplied on the
redback(using predetermined ip pools) because it is serving as the end
point on behalf of the ISPs that don't have the proper hardware(if i
remember correctly i think that it was Zoltrix, but i am not sure). If
the ISP do have the correct hardware, he can supply the ip himself, but
i cannot be sure if he can pull the tunnel to his machine or if it
remains on the redback.

This is what i gathered from the few months i am using adsl, and from my
discussions with isps. i would appreciate comments from confirmed
sources. as you can see there are many holes in the description, and
many people assume many things.

Intersting question: Does the PPTP tunnel end on the ADSL modem, or is 
it "continued" to the DSLAM? or even to the Redback servers?

Anyone know?
