I have configured an IPSec remote access VPN connection and I'm successfully able to establish the tunnel but I can not get to any of my LAN internal
resources. I'm able to ping PIX's internal interface (192.168.10.1) and even telnet to it from the VPN client, once logged into the PIX I'm able to ping all
192.168.10.0 /24 internal resources from inside interface but wont work from the VPN client (192.168.20.0 /24)
Heres the scenario
INTERNET---->1800SERIES--->PIX515e-->LAN(192.168.50.0 /24)
1800 SERIES 201.190.x.9 /30
PIX515e 201.190.x.10 /30
Below is a clean run-config regarding mostly the VPN statement for ease of reading....
