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

pptpd[12125]: CTRL: Client 11.22.33.44 control connection started
pptpd[12125]: CTRL: Starting call (launching pppd, opening GRE)

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

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

CONFIG_PPP=m
CONFIG_PPP_MULTILINK=y
CONFIG_PPP_FILTER=y
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
CONFIG_PPP_DEFLATE=m
CONFIG_PPP_BSDCOMP=m
# CONFIG_PPPOE is not set
# CONFIG_SYNCLINK_SYNCPPP is not set
CONFIG_WANPIPE_PPP=y
CONFIG_WANPIPE_MULTPPP=y
CONFIG_ISDN_PPP=y
CONFIG_ISDN_PPP_VJ=y
CONFIG_ISDN_PPP_BSDCOMP=m

It's the Microsoft VPN client.  I don't know anything more specific
than that, but I could find out....

All Linux distros should, for many reasons, not the least of which is
pty ownerships and permissions. :)

Nope, I got the pptpd RPM from rpmfind (Mandrake) and rebuilt it.

Thanks for all your help, fellas. :-)
