Good day… I’m a complete hack, aka novice, when it comes to complex networks like I have, but I do appreciate the ability to configure a great network and learn something in the process. That being said, please be very specific in your response as this is way above my skill level.
I recently upgraded my router from the RV340 to the C1111-4P as some of my new Sonos speakers weren’t connecting to the network due to the lack of proxy support on the 340. Here’s the equipment that currently makes up my network.
C1111-4P Router
Three SG350-10P Switches. One of the switches are connected directly to router in the network closet and the other two switches are connected to the first one off of the router.
Two 240AC access points one is connected to the switch off the router, the other is at a distant switch.
My issue is that I can’t access the ISP from the LAN network. The router can access it from the WAN troubleshooting shooting tool on the routers WebUi. I can access the router via console using PuTTY so if there’s anything I can do or provided via the console, please be very specific and I shouldn’t have an issue. Thank you for all your help in advance, I greatly appreciate it! I’m sure I’ll need more as I get this router dialed in!

Thank you!
The import-all command failed.

What IOS is running on the C1111?
06-28-2025 02:13 PM
Cisco IOS XE Software, Version 17.05.01a

My bad, it's "import all", i.e. no hyphen.
I found the import statement documented for 17.x:
Step 15 |
import {all | interface interface_name Example:
|
The import all command learns options from all the interfaces. The import interface learns options only from the specified interface. |

Good day! I greatly appreciate your help here! I've entered these configurations. Is there a command I can run that will display all the pertinent configuration settings we can review to ensure I have everything I need to try it on the network?

Possibly "show ip dhcp import".

Here's the result:
Router#show ip dhcp import
Address Pool Name: WEBUIPool

Is you WAN interface active, and using DHCP to obtain an IP?
06-29-2025 09:13 AM
Not yet, but if you think the configuration is close, I can give it a shot. Family is getting ready to leave for the afternoon, so I won't get looked at for breaking the network.
06-29-2025 09:27 AM
Ok.... it's in place on the network and still no access to the ISP from network devices.
Here's the results from the command:
Router#show ip dhcp import
Address Pool Name: WEBUIPool
Domain Name Option: verizon.net
Router#

Router#ping 8.8.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/13/16 ms
Router#
It's connected, but something to do with the LAN not having access to the WAN.

Are hosts correctly obtaining all needed IP info from DHCP?
Can hosts ping inside gateway or external WAN IP (on C1111)?
Is config you just posted in other thread current?

Can hosts ping inside gateway or external WAN IP (on C1111)? I can ping the DNS server from the router console.
Is config you just posted in other thread current? Yessir, it is! I haven't tried to put it in the network yet after making the commands BB suggested.

Depends on client. For example, if I open a command box on Windows 10, and enter "ipconfig", I'll see interface IPs.

So you know it doesn't work how? How did ping work?
interface GigabitEthernet0/0/0
description ISP-Router
ip address dhcp
ip nat outside
negotiation auto
!
interface GigabitEthernet0/0/1
ip address dhcp
negotiation auto
Why two configured? Which are you using?
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/1
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/1 dhcp
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 dhcp
Why more than one default route statement?

I haven't had a chance to disconnect the network yet. I have been working a bit today as well. I'll give it a try in a bit. I hooked everything up this morning to try it, and it wasn't working then, but that was before I ran the config by BB. I could ping the dns server from the terminal when I had it hooked up.

interface GigabitEthernet0/0/1
ip address dhcp

Why two configured? Which are you using? I'll remove 0/1
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/1
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/1 dhcp
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 dhcp
Why more than one default route statement? I fixed this already, I kept ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 dhcp
Question, will this use the router as the DHCP server or is this utilizing the ISP as the DHCP? I would like to use my router. I don't believe it's configured for that yet.
