Using these rules, or the iptables equivalents to be precise, I get
the following:

pptpd[12125]: CTRL: Client control connection started
pptpd[12125]: CTRL: Starting call (launching pppd, opening GRE)

pptpd[12125]: CTRL: PTY read or GRE write failed (pty,gre)=(-1,-1)

Looking better, at least.... :-)

It's the stock RH 7.2 kernel.  Here are the PPP options from the

# CONFIG_PPPOE is not set
