Hello!
I had some questions about the CIPE and bridging.
I would like to establish a CIPE tunnel between 2 IPs.  The machine running 
the CIPE would be a dual homed linux box (2.4.25 or 2.6.x) running ebtables, 
so the nics are bridged.  The tunnel destination would be an IP on the same 
subnet.
Questions:
1.  Are broadcasts and multicasts supported across the CIPE tunnel?  
2.  Where in the packet process flow are the packets placed into the CIPE 
tunnel?  Of concern is where in the iptables flow does it occur 
(before,after,in the middle)?
3.  Can a tunnel be established without encryption?  If not, is there a 
simpler application which could create a non-encrypted tunne?
Thanks in advance!!
-Scott
