[pptp-server] Dumb newbie question...

[Nicholas Oddson]

I will ensure that my Linux box is setup as you specified.  I assume that I
should use an internet address (such as 204.138.115.3) since the Linux box
is multihomed (being both the internet address as 192.168.1.1).  I have
always had the proxyarp option in my /etc/ppp/options file.

Oh - ok - that makes more sense now...   so then my connection problem
would be PPP related (and not PPTP) - it seems that PPP fails to read the
data for authentication.

Is there a reason why my ppp would be timing out and unable to read the
connection?  My ifcfg-ppp0 was original configured for a modem and I'm not
sure I know what to change appropriately for use with PPTP.

Thanks for your responsive feedback.
