Setting up New modem on C1111-8P

[Noah29]

Hi,

Noob here trying to figure out how to set up a new modem provided by ISP. 

Modem brand : FibreHome HG6142A
ISP : ViewQwest

Attached is the information from router. 

Router IP is 192.168.1.1

Really not sure what else to try.

Thank you very much!

Can not help you with the modem but with the Cisco router,  you probably need NAT on the C1111. And a default route sending all traffic to your ISP modem

conf t

int GigabitEthernet0/0/0

ip nat inside

!
int Gi0/0/0.11

ip nat inside

!
int Gi0/0/0.126

ip nat inside

!

int GigabitEthernet0/0/1 

ip nat ouside

!

ip nat inside source list NAT interface GigabitEthernet0/0/1  overload

!

access-list extended NAT

permit ip  192.168.0.0 any
permit ip  10.65.11.0 any
permit ip  10.65.126.0 any

!

ip route 0.0.0.0  0.0.0.0 GigabitEthernet0/0/1 dhcp

Hi @fla
Thank you so much for the above. I've been at this for 2 days now. Didn't expect a simple modem change to require so many changes. 

I'm stuck on,

access-list extended NAT

permit ip  192.168.0.0 any
permit ip  10.65.11.0 any
permit ip  10.65.126.0 any

Main-rtr001(config)#access-list extended NAT
                                    ^
% Invalid input detected at '^' marker.

Main-rtr001#permit ip 192.168.0.0 any
                            ^
% Invalid input detected at '^' marker.

Same goes for the other permit commands.

You can change

access-list 100 permitip192.168.0.0 any

access-list 100 permit ip  10.65.11.0 any
access-list 100 permit ip  10.65.126.0 any

Then you need to change the NAT

ip nat inside source list 100 inter.....

Hello again, 

I managed to complete the above successfully but now I'm getting a different error.

I totally have no idea what this is. 

[Flavio Miranda]

Ok. Show me the following commands

show run

show ip int br

[Noah29]

Can't thank you enough for this. 

Here's the requested information.

@Noah29 

 You have a lot of configuration on this router!! Do you need all this?

Well, despite so many configuration. I would say it should work. At least, I dont recommend add any more config. If I were to recommend something, I would recommend to remove configuration.

For example. zone-member security INTERNAL. Unless you know very well what this is doing there, I would remove it from all interfaces.

You have a lot of NAT

ip nat inside source static tcp 192.168.0.10 443 interface GigabitEthernet0/0/1 1443
ip nat inside source list NAT interface GigabitEthernet0/0/1 overload  <<<<<<You can safely remove this one
ip nat inside source route-map NAT interface GigabitEthernet0/0/1 overload
ip nat inside source list 10 interface GigabitEthernet0/0/1 overload
ip nat inside source list 100 interface GigabitEthernet0/0/1 overload

By the way this seems to be related to DHCP

%FW-6-LOG_SUMMARY: 1 udp packet was dropped from GigabitEthernet0/0/1 192.168.1.1:67 => 255.255.255.255:68 (target:class)-(External_to_Self-zone:class-default)

And this seems to show that the interfac connected to ISP is not getting IP address
