Hi guys,

This is the first time i post question here. Before, i just read your forum. Ok,i just got myself a used 1721 router with WIC-4ESW and connect to my ADSL modem using Dialer. I have configured Vlan 1 to FE/0 , FE/1 and FE/2. My ADSL modem connected to FE/0 while my PC connected to FE/1. FE/0 IP address 192.168.3.1 and FE/1, FE/2 are 10.1.201.x(DHCP) mode with VLAN 1 ip address 10.1.201.1 .
The problem here is, i can't figure out why i can't get Internet. From the router,i was able to ping to www.google.com and from PC, i was able to ping 192.169.3.1 but not google.com. I can ping the clients PC connected to WIC-4ESW.


Below is my running-config file

Hi guys,

the latest config,

ip dns

ip access-list standard 1
permit any

and i remove all the rest of access-list and add,
ip access-group 1 in at dialer 0 interface.
It work for a while, but no not working after i reboot the router.
Can you assist what happen on the router? Why it work before reboot ?
