Adding subnet to PIX 501 network

I am looking for some configuration help with a Cisco PIX 501 version 6.3(3). It is currently set up with IP 192.168.1.1 and a subnet mask of 255.255.255.0, and all clients are have IP addresses in the 192.168.1.xxx range. All clients are connecting via an unmanaged switch to the PIX, which in turn connects to the internet.

I am trying to accomplish two things. FIRST, I am trying to add an internal client with an IP address of 192.168.10.10, and allow that client to access everything (both internal and external). I also want to be able to RDP to this client from the internet. SECOND, once I accomplish this, I would like to prohibit the new client from accessing the server at 192.168.1.10 (and vice verse).

I have made an attempt to do this, but so far, no luck. So far, I have done the following:
- added (via the PDM) an inside host/network of 192.168.10.0 255.255.255.0
- added (via the PDM) an Access Rule allowing port 3389 to make it through to the client at 192.168.10.10
- changed (via the PDM) the inside interface to a subnet of 255.255.0.0 (was 255.255.255.0)
- added (via telnet) route inside 192.168.10.0 255.255.255.0 192.168.1.1 1.
Finally, I changed the IP on this client to 192.168.10.10, but left the gateway as 192.168.1.1. (I didn’t start to try to limit access for this client to the server at 192.168.1.10, as I still haven’t accomplished my first goal.) The current PIX config is detailed below.

I cannot RDP to this client, nor can I ping this client from any other computer on the 192.168.1.xxx subnet. I must have configured something wrong, just not sure what it is. Thanks for your help.

Sorry, I mis-stated one fact in my summary above, and I think it is probably important. The outside port on the PIX does not connect directly to the internet, it connects to another internal router over which I have no control. The PIX has an outside IP of 192.168.2.162. No machines on the 192.168.1.xxx network (or 192.168.10.xxx) need to access any resources on the 192.168.2.xxx network. When data leaves the outbound port on the PIX, it is destined for the internet.
