Yes, and you can see the routes installed on your client. I hope a is
_not_ 1 :-)

As you can see both, routes point to the same address, 10.8.0.5 which is
probably the other tunnel end point. What exactly does not work in this
context? Did you check the traffic using a tool like tcpdump. What
happens on the tun0 interface when you send a ping to an existing
address in 10.1.b.0/24 or 192.168.a.0/24. Check the traffic on both ends
of the tunnel. I am wondering about the details.

And whatever a or b is, obfuscating does not help here :-). After all it
is tunnelled traffic.

cheers
