[pptp-server] pptp connection with encryption and kernel 2.4.0

[werner.hofer at igs.at]

Thanks for your reply Robert!

Yes I do have the line proxyarp in my options-file

my options.ppp0 file does have the following entries:

proxyarp
lock
debug
auth
+chap
+chapms
+chapms-v2
mppe 40
mppe 128
mppe-stateless
name poseidon

my pptpd.conf file has the following entries:

speed 115200
option /etc/ppp/options.ppp0
debug
localip 192.168.1.2-50
remoteip 192.168.1.102-150
pidfile /var/run/pptpd.pid

My local Ethernet is in the Segment192.168.0.0/24
the eth0 device has the ip 192.168.0.1/32
I have 4 CIPE - Interfaces wich are all on other Segments - not
192.168.1.0/24

I do have a start/stop script there I placed the following statements:

.....
echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1> /proc/sys/net/ipv4/conf/all/proxy_arp
....
modprobe ppp_mppe
.....
startproc /usr/sbin/pptpd  || ......,

I placed the necessary iptables statements in my firewall (tcp port 1723
and ip protocol 47)

what else can it be?

Werner
