I am trying to connect to a pptp server on my company's network from a
win 2k client. but when I want to get a VPN connection, my win2k
client complaints that "Error 619: the specified port is not
connected."
My VPN server is Linux2.2.14, and I use the "ipchains" as follows:

ipchains -A forward -s 192.168.0.0/24 -d ! 192.168.0.0/24 -j MASQ
ipchains -I forward -s 192.168.2.0/24 -d ! 192.168.2.0/24 -j MASQ

192.168.0.0 is my company's network, and 192.168.2.0 is my vpn
address.

#ifconfig -a
eth0 192.168.0.1 ...
eth1 noarp up broadcast ... (for adsl)
eth1:0 192.168.2.1
gre0 ...
tunl0 ...
ppp0 ...(used by adsl)
ppp1 ...(may be used by pptpd)

when I want to get a vpn connection, some log messages will occur:
pptpd syslog:CTRL:Client 202.105.109.245 control connection started
pptpd syslog:CTRL:Starting call(launching the pppd, opening GRE)
pptpd syslog:CTRL:Allocating pty/tty pair
pptpd syslog:CTRL:Allocated pty/tty pair(/dev/ptyp0, /dev/ttyp0)
pppd 2.3.8 started by (unknown), uid 0
using interface ppp1
connect: ppp1<-->/dev/ttyp0
pptpd syslog:GRE:Discarding duplicate packet (<------ I lose this line
first, sorry!!)

LCP: timeout sending Config-Requests

Connection terminated
Exit

pptpd syslog:GRE:read(fd=10, buffer=c0ac60b0, len=8192)from PTY
failed:status=-1 error= Error -5)
pptpd syslog:CTRL:PTY read or GRE write failed(pty, gre)=(10, 11)
pptpd syslog:CTRL:Client 202.105.109.245 control connection finished

my pptpd is pptpd-1.0.1 and /etc/pptpd.conf is:

option /etc/options.pptp
localip 192.168.2.1
remoteip 192.168.2.100

/etc/options.pptp:
lock
noauth
require-chap
proxyarp

/etc/ppp/chap-secrets:
96169 * 96169 *

/etc/ppp/pap-secrets:
96169 * 96169 *

what can I open this VPN server to work?

Thanks!!
