My Current setup--

Cable Internet Modem --> Smoothwall Firewall --> Secure Home Wired Network 192.168.1.0/24 (No Problems)
|

Purple Wireless Network (172.28.1.0/16)
|
|
Cisco 871W for Wireless WPA (10.146.1./16)


So far this is what I can do. From the Cisco 871W I can ping the Internet from the Cisco device itself and reach outside Internet addresses. I can connect to the wireless network Cisco and get a 10.146.1.0/16 ip address.

Once connected to the wireless network I can ping the 10.146.1.1 gateway. I cannot ping anything on the outside Internet i.e yahoo.com. I'm not sure really what else to try as I don't have much experience with this device.

Any help would be very much appreciated.

Thank you,

Three things:
1) Your smoothwall is performing NAT services so your 871 doesn't need to. Remove ip nat outside from your f4 interface
2) under your vlan1 SVI, add bridge-group 1
3) adjust your dhcp pool to be network 10.146.0.0 255.255.0.0, default-router 10.146.1.1, dns-server 10.146.1.1

try those things and post back with any issues.

Thank you for your response. I went ahead and made the changes. Still I cannot connect to the Internet. Any additional suggestions would be very much appreciated.
 
ok, can you post your updated config?? does your firewall have a route back to the 10.146/16 network??

you mentioned you can ping the gateway from the wireless client. how about 192.168.1.0 network (your router)?

originally your NAT statements were not correct. You were missing:
int bvi1
ip nat inside
!
ip nat inside source list 1 interface vlan1 overload
!
access-list 1 permit 10.146.1.0 0.0.0.255
I believe after removing nat commands per unclerico that now you are running into a route issue.

if you can add routes go for that as trouble shooting would be easier than having to go through multiple translation tables, in the future that is


We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.
 
*oops
that should be :

int vlan1
ip nat inside

and the nat command should be:
ip nat inside source list 1 interface fa4 overload

We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.
