The vpn/dns & routing is working for me. What debug messages are you seeing when you run the command to connect in bash? what is the output of 'route' when you run it?
here is mine
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default gateway 0.0.0.0 UG 100 0 0 eth0
10.192.0.0 172.16.192.1 255.192.0.0 UG 0 0 0 tun0
172.16.0.0 0.0.0.0 255.255.255.0 U 100 0 0 eth0
