[LARTC] Problem with VPN routing from internal network + tun0 and traffic shaping

You are correct Peter.
But that is not enough to have access from client local lan to serevr client 
local lan.
The line below helpped me to fix it:
iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o tun0 -j SNAT --to-source 
10.0.0.2

So there is one more problem, how to access from the server local net 
client's local net?
Any ideas?

And how to shape traffic going via tun0?

At the moment I have htb on eth0 and imq0 to shape in and out traffic?
But what about VPN traffic which goes via tun0?

Thanks

Remus
