Hello all,
I'm having trouble setting up a second vlan to route to the internet. I have a Cisco ASA 5505 connected to my ISP(OUTSIDE) and a Cisco 881w (INSIDE) router in the back of my firewall. My vlan 10 with the network 192.168.5.1 255.255.255.0 works with pat, however vlan 15 that is on my 881w router does not route to the internet at all. I can only ping from 192.168.15.15 network to 192.168.5.1 I would like some advice on how can I make this set up work. Attached with this discussion is a picture of my topology.
Thanks in advance.
here are the show runs:

Whilst I look through your config, can you give a little more info about the cable modem? Does it contain any configuration?
03-19-2015 06:51 AM
The cable modem does not have any configuration. I cant add any to it. Its a cisco dpc3008. From vlan 10 i have no problem to get to the internet with the above configuration. My problem is just vlan 15.

Can you post the output of a pack-tracer from inside (vlan 15) to outside.
03-20-2015 11:38 AM
Can you post the output of the command "show nat"
03-19-2015 06:53 AM
I've added a pc to vlan 10 and it routes to the internet.

Hi Heber,
I have a similar network at home:
Motorola Modem>ASA5510>881W>3780>3780.
Did you ever resolve your issue?
Regards,
