Dear CIPE experts,

I am new to the list and trying to understand CIPE and get it to work. Does
anybody have a basic logical description on how get it to work ? The help I
found was not sufficient to understand it well.

I have the following situation:

1) 3 machines A,B,C connected to the internet with ADSL.
2) My university allows me to connect only with 1 VPN connection, but I
actually need A,B,C to be all connected.
3) Goal: I make a VPN connection to the university with A and tunnel all
packages for the university from/to B,C through A using other CIPE VPNs.

To use CIPE I thought to do the following:

1) I installed the CIPE-VPN adapter on all A,B,C. NOTE: they all have the
same MAC !! Is this ok for arp ?!?!?
2) I start ciosrvr on A
3) I make PEER to PEER connections A-B and A-C
4) I route on B,C all packages for the university to the CIPE-Adapters of B
and C respectively

If this make sense, how am I going to do this in the folowing ?

1) Once I have chosen an IP and MASK on A, No GW spec are necessary right ?
Any tip for an IP ?
2) On B,C I suppose I have to define peer to peer connections using the CIPE
VPN Peer Setting. How should I do this ?
3) If B is a laptop and I am in another subnet abroad, how whould I choose
the IP numbers and configuration to let it work anyway ?

Thanks a lot for your help !
