My Vpn client can connect successfully to PIX and got ip 10.10.10.40 but i can not ping to network behind PIX , i tried to trace with wireshark and the ping packet reached to PC client inside the WAN but i got request time out from VPN Client
1206: ICMP echo-request from outside:10.10.10.40 to 10.10.20.5 ID=1 seq=13310 length=40
1207: ICMP echo-reply from inside: 10.10.20.5 to 10.10.10.40 ID=1 seq=13310 length=40
another question is , is it possible to use private subnet for VPN client pool without touch any router configuration , so if i use 192.168.1.0/24 as i pool how the pc on WAN cloud with ips 10.10.20.30 can replay back the packet goes to PIX and sent to VPN client?

You need to use another IP subnet for the VPN pool - using a subset of the inside will not work.

Ok. thanks , i can reach the network that the same with PIX but i can not reach other network inside , is possible to do NAT so the user on VPN client can reach other network that i can ping from PIX
[VPN CLIENT] --->[2.2.2.2-PIX-10.10.10.20]-->[NET. 10.10.10.0/24]--[CLOUD]--[OTHER NETWORK ie. 10.10.20.0/24]
