C892FSP and ADSL Router issues

[sdawson35]

Hi,

Trying to educate myself and have failed miserably !, I have an ADSL wifi router and the 892.

The 892 is plugged into a port on my ADSL router via Gi9, I have a laptop plugged into Gi1. and it has got a dhcp address. 

I have a dhcp pool set on the 892 details below

ip dhcp pool Folly_Test
network 10.50.1.0 255.255.255.0
dns-server 192.168.1.1
default-router 192.168.1.1
domain-name Folly.local

ip domain name Folly.local

interface GigabitEthernet1
switchport access vlan 100
no ip address

interface GigabitEthernet9
ip address 192.168.1.3 255.255.255.0
ip nat outside
ip virtual-reassembly in
duplex auto
speed auto

interface Vlan100
description Folly_Test
ip address 10.50.1.254 255.255.255.0
ip nat inside
ip nat enable
ip virtual-reassembly in

ip nat inside source list 10 interface GigabitEthernet9 overload

access-list 10 permit 10.50.1.0 0.0.0.255

My problem is that from the 892 I can ping the laptop and any device on my 192.168.1.0/24 network

Folly_Router#ping 192.168.1.5
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.5, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
Folly_Router#ping 10.50.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.50.1.1, timeout is 2 seconds:
!!!!!

But from my desktop (192.168.1.5) I cannot ping 10.50.1.1, What have I done wrong ?

Hello,

is this the full configuration ?

--> My problem is that from the 892 I can ping the laptop and any device on my 192.168.1.0/24 network

The 192.168.1.0/24 network is used on your WAN link, where exactly are the hosts in that network located ?

Hello

Your host your pinging from is from the inside global address subnet and as such nat will try to translate before its checks any route table and given the  fact nat is stateless there isn't any nat translation entry from your outside host to the internal network so it fails.

Hi All,

Thanks for the reply's.

Im going to scrap the whole idea, I don't think what I want to achieve is achievable. Basically I want an environment that I can self study/learn on that is connected to the internet that connects to my domestic adsl but doesn't effect the the other devices in the house.

I was hoping to use my existing adsl wifi router but connect the 892 to one of the lan ports then I can have an isolated network but either my hardware is wrong/not compatible and or my knowledge isnt good enough to explain/achieve what I want.

Thanks anyway.
