Networking :: Make PPTP Routing / Specify An Expired Date For Each Pptp User?
Mar 13, 2010
i have a VPN server PPTPD on Centos 5.3
eth0: 62.2.2.x (public on the internet)
GW: 62.2.2.1 (cisco router)
i want to configure my ppptp server to allow users access internet with their own public ips of class 62.2.3.0 62.2.4.0 62.2.5.0
every time i configure my server all users can get thier IPs but they only go out with my server IP same as NAT not routing.
can you show me the proper configuration to make my users connect with public IP and have internet access. use specific DNS ( i did this but some users can not brows by DNS)
is there any way to specify an expired date for each pptp user.

I am trying to connect to a PPTP VPN at work, and I cannot accomplish that. Both server and client are using Ubuntu 10.10.

I'm trying to connect to a Microsoft ISA PPTP server from my Linux box. The box I'm connecting from is itself a router. I have no problem connecting a Windows XP machine to the VPN via this machine. This is fine, but I would rather connect via the Linux machine, giving me far more advanced routing options (i.e. no to send every packet from the XP box completely unnecessarily via the PPTP tunnel). The Linux router is running Debian Lenny.
I've checked iptables. There were initially some issues. I've fixed those.
Invoking pppd from the console, I can see that authentication succeeds, but then some negotiation goes wrong and the server terminates the connection. Here's the output from pppd, with the more sensitive stuff removed:
Code:
<hostname>:~# pppd call <peer> nodetach debug
using channel 19
Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xe3e45f75> <pcomp> <accomp>]
code....

I have just managed to setup a small server were I run rtorrent through och VPN tunnel pptp based. When I start up my server without starting the tunnel it looks like this.
[Code]...
I guess that something happen with the VPN connection, assigned a new ip number maybe and that that made the change.

recently i rent a xen vps intended to setup a PPTPD vpn server for me and my friends. so we can by-pass the great firewall in china and get back on ....., facebook and stuff. i have already setup the server and i can connect to it without any problem. but i still want to do some further configuration the server:
1. i want to limit the bandwidth to 400k/s per connection.
2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?

This questions is a little complex but here goes.at a central HQ I have a windows server 2008 R2 machine running routing and remote access. At my home office i have a class C lan with a Fedora 13 machine. I can get fedora 13 to connect using pptp no problem. I have my router running tomato set to redirect all traffic to teh 10.0.0.0 network to my linux server. My questions is how to I make the fedora 13 machine pass all the traffic from my network with destination 10.0.0.0 over the vpn tunnel? so for instance if i ping anything 10.x.x.x from any machine on my network it will find it and reply?

I am having trouble connecting back to my vpn at work while I'm at home. Mainly need to get our local svn repos for at home development. I successfully connected to the vpn following this [URL]..I am running Lucid Lynx 64bit and I followed the 9.10 section of the tutorial on setting up PPTP connection.
It worked fine. Then I walked away from my computer and it was disconnected when I came back 2 hours later. I was unable to connect back to it. I used my laptop which is running windows 7 and it connected just fine. So, now I am unable to connect to it and have no idea why. I viewed my system log and don't know what to do with the information. Could someone help me out on this.

I have a question regarding the use of iptables as sort of a firewall I suppose? Using a linux router which has a server machine connected to it. The router is also acting as a PPTP VPN server, which I would like to allow some friends to connect to so that they can VPN to my LAN.
The question I have is how I might be able to use iptables to apply restrictions to the VPN traffic to only access 1 IP? The server is on the LAN with an IP of lets say 192.168.1.25, and the VPN given IP range is 192.168.1.51-55. The router has the .1 IP, but the PPTP server on that router uses an IP of 192.168.1.50. How might I restrict the traffic from the VPN connections to only be able to access the .25 server, and possibly only on certain ports? I don't want to allow the VPN connections full access to everything on the LAN and especially not to WAN.

I can't get the CentOS version of pptpd to work. I have a Debian 6 one with the exact same setup that does work. The required port is open according to various external port checking websites. It's giving me random errors when trying to connect, including 800, 809, 619. This is what I did so far;
Step 1. Installing pptpd the pptpd is the daemon that runs the pptp server.
To install this:
Step2. Next you will need to modify the pptpd.conf
Step 3. The vpn server is now configured and now you must setup authenticated users:
Step 4. When pptpd was installed it started automatically so we will need to restart it to apply the changes:
Now, if you would like to add internet access over this vpn, you can do this:
And find the line for ipv4 forwarding and make sure it = 1:
Then use iptables to get the net forwarded:

Just moved over from the dark side (Vista) and was wondering how I can get two (or more) PPTP VPNs connected at any given time. I usually attempt to multi task (although swambo says I can't) and work on various clients' servers at the same time. The GUI network manager thingy only allows me to dial up one VPN at a time. Is there perhaps a cli version and if so where would I go to get a tutorial on this please. BTW, running F11 32bit. Tried Debian and Ubuntu as well and found F11 to blindingly fast on my DualCore Toshiba laptop. Pity I can't see the additional 1Gb of RAM though. (4Gb in total).

I'm trying to get a pptp server up and running. The server starts just fine, but encounters errors when a client tries to connect.
Code:
CTRL: I wrote 32 bytes to the client.

Dec 29 23:27:48 frankenstein pptpd[9403]: CTRL (PPPD Launcher): program binary = /usr/sbin/pppd

I assume the failed read line is the culprit. I am currently running on a test machine. There is no firewall. I read on this error points to a firewall misconfiguration, but there isn't one.

I am a newcommer to Centos. I should connect to internet via a pptp vpn connection. I created the connection in "network connections". In other distrows I could connect to created pptp vpn connection simply by clicking on network-manager-applet and selecting the connection, but there is no network-manager-applet in Centos. Is there any way to connect to the vpn connection I created or I should go to do it by manually editing config files?

I thought configuring a vpn would be a piece of cake, but it seems I'm missing something.
I'm attempting to create a vpn (pptp) using the networkmanager (0.7.1). I enter the gateway (I assume thats the server I'm trying to connect to) and my login information. What is the NT Domain?
When I try to connect it only tells me after a while that it failed to do so. How can I find the information on what went wrong in the process?

I currently managed it to get a pptp-connect to my home network. now I have another little problem. NetworkManager always routes the whole network traffic over my home network if i am connected to the home network.If i set the "Use this connection only for resources on its network" I have do manually say:
Code:
route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0
After that only the correct traffic runs over the vpn. Now my question is it possible to setup the route via the networkmanager gui?
