I followed this guide to setup openvpn on my home network.

I accidentally downloaded ubuntu 12.10 at first and without noticing, I went ahead and followed the guide...

Then I did some stuff from here: push "redirect-gateway def1" iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE

to enable browsing.

OpenVPN was fully function.

By that I mean, I was able to remote in (access internal services) and mask my IP when browsing from the outside.

Then I realized that I wanted ubuntu 12.04 so I followed the same process on a new install.

Now the problem is that the DNS does not resolve.

I noticed that downloading openvpn downloaded resolvconf which I uninstalled and attempted to go about this manually.

Here is some stuff from my system:

openvpn server.conf:

mode server
tls-server

local 192.168.1.101 ## ip/hostname of server
port 80 ## default openvpn port
proto udp

#bridging directive
dev tap0 ## If you need multiple tap devices, add them here
up "/etc/openvpn/up.sh br0 tap0 1500"
down "/etc/openvpn/down.sh br0 tap0"

persist-key
persist-tun

#certificates and encryption
ca ca.crt
cert server.crt
key server.key  # This file should be kept secret
dh dh1024.pem
tls-auth ta.key 0 # This file is secret

cipher BF-CBC        # Blowfish (default)

Any help would be appreciated

I'm running Ubuntu 12.04 as a virtual machine on my Mac. Since I am unable to get the virtual machine to have full access to my WiFi card, I bought another USB WiFi card to use.

This is my WiFi card.

If you are unfamiliar with Virtual machine, as far as I know, since the Ubuntu has its own card now, it shouldn't matter.

I have followed these guides with no luck:

• https://help.ubuntu.com/community/WifiDocs/WirelessAccessPoint
• http://www.danbishop.org/2011/12/11/using-hostapd-to-add-wireless-access-point-capabilities-to-an-ubuntu-server/

The problem is that the WiFi connection appears on all of the machines that I have in my house: 2 iPhones, Dell machine running Ubuntu and two Macbooks. However the connection times out on all of these machines.

Questions:

1. Could this be a driver issue if that same WiFi card can connect to other WiFi points and use its internet
2. Could this be DHCP related? I would think not. It should at least get a 169.X.X.X address? No?
3. Any solutions for me?

I have followed This guide and also the documentation for pptp vpn and my vpn connects. It even allows me to go on the web and search it. However, when I go to cmyip.com; it displays my personal ip (as if the vpn is not connected) I have other vpns (i used ddwrt pptp) and it displays the ip address of the vpn server im connected to? Let me know how i can fix this.

Same issue as here and it remains un answered.
