Installed Xen and now I'm having problems connecting to VPN (routing?)

**RyanRahl** · March 22nd, 2012

I just bought myself a shiny new laptop so I could teach myself to use Xen and I installed the hypervisor and all the tools, but the book I wanted to use is stored on my VPN. When I connect to my VPN (OpenVPN) everything authenticates just fine, however, I don't get an IP address and I can not communicate with any of the hosts on the VPN. I assigned an IP manually but it didn't help, I'm sure I am missing something obvious, does anyone know what I should do here.

my ifconfig looks like this:

Code:

my route -n looks like this

the syslog says the following with
cat /var/log/syslog | grep vpn

My laptop is running Ubuntu 11.10 and the server is running 11.04

The VPN network is 192.168.27.0/24
and when I ping it looks like:

Code:

ryan@the-ship:~$ ping 192.168.27.1
PING 192.168.27.1 (192.168.27.1) 56(84) bytes of data.

^C
--- 192.168.27.1 ping statistics ---
25 packets transmitted, 0 received, 100% packet loss, time 24192ms

What should I do?
