[Openvpn-users] routing setup: wireless subnet through tunnel

["Sancho2k.net Lists" <lists@xxxxxxxxxxxx>]

I have set up an OpenVPN tunnel between a host on my wireless network 
(10.0.2.20) and a server on my internal LAN (10.0.1.4). I can ping 
opposite ends of the tunnel from each of the hosts and want to set up 
the systems so that all traffic from the wireless client goes over the 
encrypted tunnel and all routes perform correctly.


             +-----+ 10.0.2.1       |  Wireless (10.0.2.0/24)
INTERNET ----|  R  |----------------|  Network
             +-----+                |   +-+
                |10.0.1.1           |-- | |
                |                   |   +-+
                |                      10.0.2.20
           ------------
            |                            ^ (tun0: 10.0.3.2)
           +-+                           |
           | |                           |
           | |  <=========================  <= OpenVPN tunnel
           +-+   (tun0: 10.0.3.1)
        10.0.1.4

The current setup requires that the wireless clients first make an ssh 
connection to 10.0.2.1 (thier default gateway) to authenticate to the 
firewall/router (R) (OpenBSD/authpf). An SSH connection is maintained so 
traffic travels between the wireless clients and the rest of the 
network. I'm not sure if introducing openvpn will require that I 
reconfigure this aspect of the setup.

Is the proper setup to configure 10.0.3.1 as the default gateway for the 
wireless clients so that all traffic flows over the openvpn tunnel?

TIA,

DS
