Hi Cliff,

First let me say that the "raw" serial implementation is smaller, better, faster
and more reliable than the ppp implementation. I no longer recommend using the
ppp option.

However, having said that, it *should* work. Do you have each end of the PPP
connection set to different addresses? In other words, do your ha.cf files
assign each end of the connection a different address, or do they both set the
IP address to 192.168.0.1?

Have you started up everything with lots of debug? If you start up heartbeat
manually with 5 or so -d options, it will dump out lots of semi-interesting
information.

Thanks!
