Ubuntu Networking :: 10.04 - How To Use PPTP After Setup
Oct 15, 2010
Trying to connect to my office as a PPTP client, I have setup my PPTP connection in Ubuntu 10.04, and the connection is active, as I can see from the top bar, and the output of ifconfig:
Code:

Now I want to access the folder named ABC on the remote PC with IP address of 192.168.0.12, with username USER1 and password PASS1.

I'm trying to setup IPv6 in a PPTP client configuration on Maverick, but in network manager only IPv4 is available.
On LAN and WLAN IPv6 is working fine but I want to avoid when using a VPN all IPv6 connection are bypassing the VPN which compromises the VPN to a certain extent ..

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'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 a Slicehost VPS and I'm trying to set up PPTPD on it. I only have one IP address (the public IP of the box). All the PPTPD howto's I've seen rely on assigning remote clients IPs from the local subnet (e.g. the PPTD server's local IP is 192.168.0.20, and remote IPs are taken from a pool of 192.168.0.30-40).
However I don't think I can do that as I only have the one IP address on Slicehost's network - that public IP (and all other IPs in the segment are public). So what I really want to do is to be able to create a private LAN segment or virtual network adapter and have VPN clients assigned addresses in that segment, then routed out onto the Internet effectively using the PPTPD box as a router. I am using Ubuntu Hardy (LTS).

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 am running 64-bit 9.10 on a Acer Aspire 1810T. I can connect to the internet via both wifi and the Novatel U998 modem. I have a PPTP VPN that works correctly via wifi, but does not work via the modem. The obvious problem would be that the ISP is doing something... but I'm dual booting Windows 7, and the ISP's Windows based software is able to connect to the VPN without issue.
I'm running VMWare player to be able to access my required Windows apps, so I'm almost in a position to dump MS if I can get this VPN issue resolved.

I'm using Kubuntu 9.10, my pppd version is 2.4.5 and pptp is 1.7.2 I'm trying to connect to the iPredator VPN service, but I keep running into problems with LCP. I've tried using knetworkmanager, nm-applet, kvpnc and plain old text-based configuration to no avail. Here's a snippet of pppd's output:
[Code].....
(I've got "defaultroute" in my /etc/ppp/peers/ipred config file.) Any ideas what could be causing this? Could it even be my router? It claims to support PPTP, but considering it claims a lot of other things which aren't true, I wouldn't be surprised if it was the culprit.

I've configured a pptp VPN using KNetworkManager. It works fine. Now I want to have it started automatically then my network interface is assigned a particular IP from my home DHCP server. I don't need it in other places. I guess there is no such built in functionality, but may be it can be scripted somehow?

I am using relakks.com VPN Service and set it up with gnome's default nm-manager interface. Everything is just perfect when I'm browsing the web. I can do it for hours and nothing happens. On the other hand, when I open up a torrent client - after 15 seconds to 2 minutes - I get a nice kick off the VPN.
It goes like this:
Code:
Sep 20 08:25:11 NPC pptp[3496]: nm-pptp-service-3490 warn[decaps_gre:pptp_gre.c:426]: discarding bogus packet 94236 (expecting 93663)

I managed to set up a PPTP VPN connection in Ubuntu 10.04, and it worked first time.This was about 3 months ago. It was working yesterday (Oct 05 2010), but when I came to log in to the VPN today it doesn't work. I tried the same VPN connection on my wife's laptop which runs Vista and it works. I have tried re-entering the details, even deleting and setting up from scratch via network manager. And yes I have the correct VPN plugins. what I should do. Is there a log file so I can have a look at it to see what the problem is. If there is where is it located. The computer is able to connect to the internet without any problems, just can't connect to the VPN. The only thing I can think of is that the update manager popped up this morning so a few things have got updated today. maybe something in there broke the VPN connection.

I use a PPTP VPN for privacy and bittorrent. I have been over all very happy, only taking about a 1/4 hit to my over all network speed. However, I recently downgraded my VPN package, and the new sever I connect through is sometimes unstable with a high throughput. Because of this I am trying to find a way to block ALL (HTTP, bittorrent, email, etc) outgoing network traffic when the VPN fails, and then resume the traffic when the VPN reconnects. Essentially forcing all data through the VPN, and creating the illusion of simply having no network connection to the outside world at all when the VPN is offline/re-connecting. This is opposed to the current situation when the VPN will fail, all my traffic will switch to direct (visible) access through my ISP, and the VPN will re-establish sometime later (2-3mins, normally. Unless I manually restart it sooner).
I have tried Google, but have only been finding information on configuring local web access outside of the VPN for the sake of speed. Information of which I cannot seem to find a way to apply to this.

I've setup a PPTP server on my ubuntu 11.04. PPTP settings seem to be OK and I can connect to my machine from a Windows PPTP client. But then I dont have access to Internet from my Windows machine. Authentication is successful and I can see GRE traffic to my PPTP interface on my Ubuntu, but I can't reach any host (including Internet) after my Ubuntu machine. I suspect this is a routing or NATing issue.

Running Ubuntu 11.04 Server 32bit fresh install
I did this walk-through trying both iptables and ufw
I am able to connect to my VPN server using both windows 7 and Ubuntu desktop just fine, and using wireshark verify that all packets are being compressed and sent through the VPN tunnel.
Many sites work but there are several that will not load while using the VPN, one of them is ubuntu forums also sourceforge.
I can ping the servers while connected but the websites just will not load, and time out. The second I disconnect from the VPN they load instantly.
