OK, seems that you are only missing a little detail.
Based in your scenario, I assume that your wireless clients are provided a Default Gateway of 192.168.1.1, which is your wireless router.
If this is the case, you must have a static route between 192.168.1.X network and 192.168.10.X network with a gateway of 192.168.1.6 from the wifi side, and a static route of 192.168.10.6 from the 192.168.10.X side.
Think this way, your RRAS server (without any further detail from your config) is the *only* machine that knows these two networks. So, it must be the gateway and allow routing between them.
As almost allways there is more than one way to put that to work, but that depends on further information about your wireless router (it’s cappabilities which i personnaly don’t know), and if the phisical network can be changed.
Thank you very much Saturno. I have followed ur comments and has been solved the problem accordingly. Thank you again, u r really wise in networking.
