Do you have split tunnel configured? if you do, you would need to add the 192.x.x.x network.
Also, do you have NAT exemption configured? if you do, you would need to include the 192.x.x.x network.
I assume that you already have static route to reach the 192.x.x.x network from the ASA? and the 192.x.x.x network knows how to route to the vpn client pool subnet, ie: via the ASA?
