I have been trying to get PPTP to work correctly over a Pipeline 130, using
the built-in firewall. I have a syslog daemon running on a Win2000 machine
to monitor the router at the moment. When I try to make a PPTP connection
from the outside world, I get the following response:
05-26-2000 10:38:46 Local7.Info Gatekeeper ASCEND: wan1
tcp xx.xx.xx.x;1723 <- yyy.yyy.yyy.yy;1026 62 syn<010>
05-26-2000 10:38:48 Local7.Info Gatekeeper ASCEND: wan1
47 xx.xx.xx.x <- yyy.yyy.yyy.yy 94 !pass (reject)<010>
05-26-2000 10:38:50 Local7.Info Gatekeeper ASCEND: wan1
47 xx.xx.xx.x <- yyy.yyy.yyy.yy 94 !pass (reject)<010>
05-26-2000 10:38:54 Local7.Info Gatekeeper ASCEND: wan1
47 xx.xx.xx.x <- yyy.yyy.yyy.yy 94 !pass (reject)<010>

05-26-2000 10:39:22 Local7.Info Gatekeeper ASCEND: wan1
47 xx.xx.xx.x <- yyy.yyy.yyy.yy 66 !pass (reject)<010>
Gatekeeper is the name of the router.
xx.xx.xx.x is my PPTP Server behind the firewall.
yyy.yyy.yyy.yy is my machine at home.
The first line basically tells me that the initial connection to port 1723
(PPTP) is established. Then I get a number of lines that, from what I can
tell, say that a connection on port 47 fails. I know that 47 is the Generic
Routing Encapsulation (GRE), and I have set up a rule to allow it to be
passed. But I can't tell what kind of packet it is trying to pass. The
first line clearly states that the 1723 connection is a TCP Packet. But the
second line just says 47. Nothing more.
I am also curious as to what the numbers towards the end of the line refer
to (62, 94, and 66). I am assuming it is the length of something. Just a
guess.
