Hi, I am trying to install tunnel client on my lan.
I have a linux machine A with a private address 192.168.200.2 and a linux
machine B with
two cards: one 192.168.40.2 (private address)and one 193.205.242.52(public
address) towards Internet . ( Redhat 6.0 kernel 2.2.12)
Ifconfig of my linux machine B is:
eth0 Link encap:Ethernet HWaddr 00:C0:F0:3B:EC:53

On machine A I have installed my linux pptp client pptp-linux-1.0.2 and on
my machine B I have
installed pptp server pptpd-1.0.0.
On server B I have:
file /etc/ppp/options
debug
name "elle" ( it is the name of my Tunnel server)
auth
require-chap
proxyarp
file /etc/pptpd.conf
speed 115200
localip 193.205.242.80 ( a public address which I own)
remoteip 193.205.242.81( a public address which I own)
file /etc/ppp/chap-secrets
"kate" "elle" root *
( kate is the name of my client)
When I am on my server B I run these:
1. killall syslogd
2. /usr/sbin/syslogd
3. /usr/local/sbin/pptpd
At this point on my client A I run:
ppptp elle (elle is my tunnel server B)
the system B (tunnel client) answer is:
(unknown)[628]:log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:531]:Client
connection established
(unknown)[628]:log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]:Outgoing call
established
On my tunnel server the system answer is:
No free connection slots or IPs available -no more clients can connect
Is it now the tunnel right established?
At this point I think I can run all applications from my private LAN towards
Internet through tunnel ( for example ping) but no packets go out from my
machine B!!!
Can you help me?
Is right this setup?
Have I to add some particular route on my server or on my client?
Thanks a lot Raffaele Pellicciotta
