Hi,
I am trying to implement a small vpn solutions with mpd as pptp server and
pptpclient from home to office. I have setup also in other implementations
and it works fine, but I need for this situations pptp server...
The office is connected directly to the net, while at home I am using user
ppp and a PPPoE connection.
The situations is this one:
Home : 10.254.254.1/24 pptpclient from the ports.
Office: 192.168.0.1/24 , 194.243.20.91 real ip , mpd as pptp server
This is the config for the mpd - pptp server:
--- mpd.links ---
pptp:
set link type pptp
set pptp self 194.243.20.91
set pptp enable incoming
set pptp disable originate
--- mpd.conf ---
pptp:
new -i ng0 pptp pptp
set iface disable on-demand
set iface enable proxy-arp
set iface idle 1800
set bundle disable multilink
set link yes acfcomp protocomp
set link no pap chap
set link enable chap
set link keep-alive 10 60
set ipcp yes vjcomp
set ipcp ranges 192.168.0.1/32 192.168.0.70/32
set ipcp dns 192.168.0.1
set bundle enable compression
set ccp yes mppc
set ccp no mpp-e40
set ccp yes mpp-e128
set ccp no mpp-stateless
--- mpd.secret ---
mylogin "mypwd"
For the pptpclient I have added to my ppp.conf the following lines:
--- ppp.conf ---
vpn-pptp-cof:
set authname mylogin
set authkey mypwd
set timeout 0
set ifaddr 0 0
add 192.168.0.1/24 HISADDR
# alias enable yes
I run on the server:
mpd pptp
and on the client:
pptp 194.243.20.91 vpn-pptp-cof
where 194.243.20.91 is the real ip of the server (like in the links section).
I think the connections is fine because...
On the CLIENT:
a new tun device (the tun0 is the user ppp with the PPPoE on the DSL
cable) is created on the client side with the requested ip address:
tun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1498
inet 192.168.0.70 --> 192.168.0.1 netmask 0xffffff00
Opened by PID 2152
and the appropriate routing added:
192.168.0 192.168.0.1 UGSc 0 0 tun1
192.168.0.1 192.168.0.70 UH 1 3 tun1
On the SERVER:
ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> mtu 1496
inet 192.168.0.1 --> 192.168.0.70 netmask 0xffffffff
the netstat -rn:
[...]
192.168.0.70 192.168.0.1 UH 0 3 ng0
192.168.0.70 00:10:5a:dc:21:f6 UHLS2 0 0 xl1
But when I try to use a ping I receive:
[...]

[pptp] LCP: protocol 0x2145 was rejected

and so on...
I tried to reverse the client server hosts, so mpd behind user ppp and
pptpclient alone, but I get the same results.
I have to say I have tried only with pptpclient from the ports not from any
windows implementation...
Any idea ?
Thanks to all for attention...
