Cisco ASA 5505 - Remote VPN connection problem getting to internal machine

I believe I am missing one line but cannot think of what it is.  Here is an excerpt of the setup:

interface Vlan1
 nameif inside
 security-level 100
 ip address 192.168.10.1 255.255.255.0

access-list 101 extended permit udp any any eq isakmp
access-list 101 extended permit udp any any eq 4500
access-list 101 extended permit esp any any
access-list 101 extended permit tcp any any eq ftp
access-list nonat_clientvpn extended permit ip 10.1.10.0 255.255.255.0 192.168.20.0 255.255.255.0
access-list splittunnel standard permit 10.1.10.0 255.255.255.0
access-list nonat extended permit ip 10.1.10.0 255.255.255.0 192.168.20.0 255.255.255.0

nat (inside) 0 access-list nonat
nat (inside) 1 0.0.0.0 0.0.0.0
access-group 101 in interface outside
(this may not be necessary)  route inside 10.1.10.0 255.255.255.0 192.168.10.1 1

Layout:

Modem -> Cisco ASA 5505 (Vlan1 192.168.10.1) -> (Wan 192.168.10.2) Netgear N600 router (Lan 10.1.10.0) -> workstations (server=10.1.10.34)

I can make a VPN connection with the Cisco ASA 5505.  I am unable to ping or use the built-in Microsoft remote control (terminal services) to get on any machine.  The "packet-tracer" indicates the traffic is being dropped due to the implicit deny.

What am I missing?  Thanks.

according to the rule below the 10.1.10.0 network has access to the 192.168.20.0 network.

access-list nonat extended permit ip 10.1.10.0 255.255.255.0 192.168.20.0 255.255.255.0

is it supporse to be 192.168.20.0 or 192.168.10.0 that you are trying to access??

Hello, thank you for your reply.

192.168.20.0 is the client (remote) vpn pool
192.168.10.0 is the local network (VLan1 inside interface is: 192.168.10.1)
10.1.10.0 is on the other side of the 3rd party router with its (Netgear) WAN interface having an IP address of 192.168.10.2

ASA
  WAN - outside (also the remote VPN clients are coming in through here with the IP address of 192.168.20.x)
  Lan - 192.168.10.1 (Vlan 1 inside)

Netgear
  Wan - 192.168.10.2  (directly connected to ASA on the ASA's inside interface)
  Lan - 10.1.10.0  (all workstations are on this side)

Does that help?

Thanks.
