Clients unable to browse the internet on Cisco 871 K9 Router

tosino489
Level 1
Level 1

Hi Everyone,

i just purchased my Cisco Router 871 K9 Version running this System image flash:c870-advsecurityk9-mz.124-4.T8.bin"

I am trying to configure this Router for Home use so that i can block some Web traffic (Porn sites, Movie sites because of Children) but i realised i was unable to apply the Access list Match-class version url (http host).

My major problem is even the basic config on the router. The WAN has a DHCP IP assignment with Network 192.168.1.0

The Lan is expected to have 192.168.3.0 Network. The IPs appears to be correctly assigned but not able to ping the internet on the Router. Local client also cannot resolve DNS. here is my cofig file. 

Please assist.

Hello,

Fastethernet 0-3 are switchport. You should not have any problem. Can you check the IP addresses and sunbet masks configured on two of PCs. They can not ping eachother? Do you have any firewall or anti virus installed on the PCs. Try to turn windows firewall off .
