I am getting a public ip from the modem and DHCP looks fine.
I think problem is with FastEthernet1 shows no IP and can not ping my PC. PC displace the IP of 192.168.100.2 and proper DNS and gateway info. I am missing something please help

Thank you in advance.

I thought 1700 series config was done on the Ethernet not the vlan interface?

you will either need to put vlan 1 and fa1 in the same BVI for your PC to work, simliar to a 8xx series setup

Or you need to move the Vlan1 conf to fa1:

interface FastEthernet1
ip address 192.168.100.1 255.255.255.0
ip nat inside
ip virtual-reassembly



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

Thank you for your advice.

I tried to reasign the Vlan1 to Fa1 and I get message

(config-if)#ip address 192.168.100.1 255.255.255.0

% IP addresses may not be configured on L2 links.

I think I can not config Vlan on this port because its just L2

Is there another way I can get that configure. I don't know much about BVI

Thank you again for any help.
