Using ubuntu 10.04 on both ends.
We have a client and server machine on the SAME network attempting to make a vpn connection. We use the config files from here and made minimal changes.
The server and client start and seem to connect without any trouble. The server looks like:
Wed Feb 23 22:13:22 2011 MULTI: multi_create_instance called

On the client side the connection looks like:

Wed Feb 23 22:20:10 2011 Initialization Sequence Completed
The openvpn server has been configured to assign ip addresses in the range 10.8.0.* and the client has been given 10.8.0.50. When I run the following nmap from the client:
Starting Nmap 5.00 ( http://nmap.org ) at 2011-02-23 22:04 EST
Host 10.8.0.50 is up (0.00047s latency).
Nmap done: 256 IP addresses (1 host up) scanned in 30.34 seconds
Host 192.168.1.1 is up (0.0025s latency).
Host 192.168.1.18 is up (0.074s latency).
Host 192.168.1.41 is up (0.0024s latency).
Host 192.168.1.55 is up (0.00018s latency).
Nmap done: 256 IP addresses (4 hosts up) scanned in 6.33 seconds
If I run an nmap from the server on 10.8.0.* I get nothing.
If the client has two interfaces (wireless and tap device) when you look for a certain ip address, how does it decide which interface to connect on?
