I have two openvpn clients and a server using shared keys. I have internal routes specified in the ccd directory for both clients, but when they connect, the server only creates the internal route for one of them, despite the logs saying it's creating both. Both clients and the server use the "--script-security 2" command-line option. Can anyone think of why it would do this ?

My ccd files are:

client1:

iroute 192.168.0.0 255.255.255.0

client2:

iroute 10.0.1.0 255.255.255.0

My log file shows the following (cropped):

And after both clients have connected, the routing table looks like this:

192.168.150.2   0.0.0.0         255.255.255.255 UH        0 0          0 tun0
203.209.167.192 0.0.0.0         255.255.255.224 U         0 0          0 eth0
192.168.150.0   192.168.150.2   255.255.255.0   UG        0 0          0 tun0
192.168.0.0     192.168.150.2   255.255.255.0   UG        0 0          0 tun0
127.0.0.0       0.0.0.0         255.0.0.0       U         0 0          0 lo
0.0.0.0         203.209.167.193 0.0.0.0         UG        0 0          0 eth0

As you can see, it's created the route to 192.168.0.0/24 (client1) but not to 10.0.1.0/24 (client2), even though the log says it's been created. Any suggestions why ?
