Mandrake 9.0 Vpn Mit pptpd?

#1 Servus erstmal
Also ich hab folgendes Problem:
Ich habe mit Mandrake Linux 9.0 und PPTPD versucht auf meinem Einwahlrechner (Router) einen VPN Server einzurichten. Miein Zock-Pc ist per hub an den router angeschlossen. Wenn mich ich per laptop von nem freund aus am linuxserver anmelde, kann ich zwar auf den router zugreifen, aber nicht auf meinen zock-pc. Ich bin schon jegliche variante durchgegangen und bin am ende meines wissens angelangt.Weiß jemand rat?

Meine options.pttpd
name Server
lock
mtu 1472
mtu 1472
multilink
proxyarp
auth
ipcp-accept-local
ipcp-accept-remote
lcp-echo-failure 30
lcp-echo-interval 5
deflate 0



Meine pttpd.conf:
################################################################################
#
# Sample PoPToP configuration file

# for PoPToP version 1.1.3
#
################################################################################

# TAG: speed
#
# Specifies the speed for the PPP daemon to talk at.
# Some PPP daemons will ignore this value.
#
speed 115200

# TAG: option
#
# Specifies the location of the PPP options file.
# By default PPP looks in '/etc/ppp/options'
#
option /etc/ppp/options.pptpd

# TAG: debug
#
# Turns on (more) debugging to syslog.
#
#debug

# TAG: localip
# TAG: remoteip
#
# Specifies the local and remote IP address ranges.
#
# You can specify single IP addresses seperated by commas or you can
# specify ranges, or both. For example:
#
# 192.168.0.234,192.168.0.245-249,192.168.0.254
#
# IMPORTANT RESTRICTIONS:
#
# 1. No spaces are permitted between commas or within addresses.
#
# 2. If you give more IP addresses than MAX_CONNECTIONS, it will
# start at the beginning of the list and go until it gets
# MAX_CONNECTIONS IPs. Others will be ignored.
#
# 3. No shortcuts in ranges! ie. 234-8 does not mean 234 to 238,
# you must type 234-238 if you mean this.
#
# 4. If you give a single localIP, that's ok - all local IPs will
# be set to the given one. You MUST still give at least one remote
# IP for each simultaneous client.
#
localip 192.168.6.40
remoteip 192.168.6.141-145

# TAG: ipxnets
#
# This gives the range of IPX networks to allocate to clients. By
# default IPX network number allocation is not handled internally.
# By putting a low and high network number here a pool of IPX networks
# can be defined. If this is done then there must be one IPX network
# per client.
#
# The format is a pair of hex numbers without any 0x prefix separated
# by a hyphen.
#
#ipxnets 00001000-00001FFF

# TAG: listen
#
# Defines the IP address of the local interface on which pptpd
# should listen for connections. The default is to listen on all
# local interfaces (even ones brought up by pptp connections, thus
# permitting pptp tunnels inside the pptp tunnels).
#
#listen 192.168.0.1

# TAG: pidfile
#
# This defines the file name in which pptpd should store its process
# ID (or pid). The default is /var/run/pptpd.pid.
#
#pidfile /var/run/pptpd.pid
