How can I force all internet traffic over a PPTP VPN but still allow local lan access?

linux-howto

http://serverfault.com – I have a server running Linux Mint 12 that I want to keep connected to a PPTP VPN all the time. The VPN server is pretty reliable, but it drops on occasion so I just want to make it so all internet activity is disabled if the VPN connection is broken. I'd also like to figure out a way to restart it automatically, but that's not as big of an issue since this happens pretty rarely. I also want to always be able to connect to the box from my lan, regardless of whether the VPN is up or not. Here's what my ifconfig looks like with the VPN connected properly: eth0 Link encap:Ethernet HWad (HowTos)

Hi everyone.

It's been a long time since I used linux and what little I learned from my first shop bought box of suse, is well and truly forgotten :(

here's my problem, I hope someone can help.

I've been having daily issues with my wireless connection, running Ubuntu 11.10. My wife's laptop and my daughter's netbook both connect with no problem and they can stream Netflix with rarely any issues - both running Windows 7.

I have to re-enter my router's password pretty often when I'm surfing the web.

Hello.

I have 2 Ubuntu servers, one is acting as a firewall/proxy/pptp server, with 3 network interfaces. One WAN and 2 LAN interfaces.

The other server acts primarily as a SAMBA server.

I have the PPTP server configured on the firewall, and I can connect and browse the internet without issue.

Hello everybody! The problem is: I've got ubuntu server machine with 2 eth interfaces ex: eth0, eth1. eth0-internet, eth1-lan. And also I've got pptp connection to internet connection through eth0. In iptables I've got two nat rules for both eth1->ppp, eth1->eth0(reason: if ppp connection died). In eth1 network I've got audiocodes mp-201 VoIP to analog adapter.

I have the most recent Ubuntu 12.04. I can access the Internet by cable anywhere, and I can access a neighbor's Internet connection wirelessly, but I cannot access my own internet wirelessly. It shows up as having an "excellent" signal, but it the actual Internet does not show up. Firefox tells me that I am experiencing an Internet connectivity issue.

I'm using a virtual Ubuntu Server (on Amazon EC2) and I want to connect to a PPTP VPN server to route outgoing traffic through this connection. To do this, I specify the following two options:

defaultroute replacedefaultroute

This works - but the moment the tunnel to route the traffic is established, my SSH connection to the server is broken and I can't reconnect.

I'm using vyprvpn as a VPN provider and I would like to make my Ubuntu 12.04 server connect to it via pptp-linux. I only have the option of using the command line to connect so I used this guide: https://wiki.ubuntu.com/VPN

And it seems to work, but, I don't think I'm sending my data through the connection. My server has a static IP and I tried putting that IP in the settings.

PPTP server with NIC aliases 21 weeks 3 days ago

I have set up a VPN on a VPS Server using PPTP. I have one NIC with two aliases.

eth0 eth0:1 eth0:2

The 3 interfaces have public addresses.

This question is Not about how to setup VPN on an Ubuntu server.

I have an Ubuntu server running and connected to the internet. I also have a VPN service (PPTP) running on another Linux machine. Now all I want to do is configure this Ubuntu server so that all the internet traffic it generates goes through the VPN.

How can I achieve this?
