Hi Tom:

First, thank you for the help thus far.
Ok, I know that I will need a route to\28
eventually, but my problem is I can't ping the
opposite ends of the thunnel from each side. The pings
from the Cisco are getting to the Linux box as shown
in the tcpdump...the linux box then responds but it
deems the Linux reponses are NOT getting encrypted by
Openswan ans there is no ESP packet leaving ppp1. When
the pings arrive from the cisco, first an ESP packet
arrives and then the decoded icmp is there...at least
that's what it looks like to me.

I'll have to check my shorewall setup, especially the
shorewall.conf to make sure I'm writing everything to
the log as presently, nothing is showing up in syslog
to give me a clue.
