Problem with my cisco 897wav-e-k9

[MattiaBucciarelli79339]

hi everyone, i have a problem with my router, i need to connect it via wan and use it like a normal router, i can configure the wan, i can ping some sites, but if i connect my pc via ethernet to the g0 i don't have any connection, and if i try to configure the ip address it gives me some errors

 here is my running configuration:

router#sh run

Thank you very much Georg, but I don't know the commands, this is my first Cisco router and I don't really know what commands I must use...

[Richard Burts · Accepted solution]

The original poster tells us that " but if i connect my pc via ethernet to the g0 i don't have any connection, and if i try to configure the ip address it gives me some errors". It is pretty clear that this router is treating those interfaces as layer 2 switch ports and as such would refuse any attempt to configure IP addressing on them. @Georg Pauwen has suggested changes to the config and it looks to me like they do provide a workable solution. But the original poster also tells us "I don't really know what commands I must use..."  

The original poster told us that he could configure the wan so I assume that he is familiar with how to get into configuration mode. Once in configuration mode the original poster just needs to copy and paste the changes that are suggested such as 

--> ip dhcp excluded-address 192.168.1.1
!
--> ip dhcp pool LAN
--> network 192.168.1.0 255.255.255.0
--> default-router 192.168.1.1
--> dns-server 8.8.8.8

Of course do not include the --> in what you paste. Also some of the commands are to be made in interface config mode and to do that the original poster must include the interface command before inserting the changes suggested by Georg such as 

interface GigabitEthernet0
switchport

and 

interface GigabitEthernet8
ip nat outside

and

interface Vlan1
ip address 192.168.1.1 255.255.255.0
ip nat inside

Otherwise it should be a straightforward cut and paste the suggested changes into the config. After pasting those changes the original poster should use exit or quit to get out of config mode and should then use the copy running-config startup-config to save the config changes.

[MattiaBucciarelli79339]

Thank you so much for the help @Richard Burts and @Georg Pauwen ,

but I still can't have an internet connection via ethertnet to my pc, the command switchport when I paste it gave me error that was uncomplete command, so I wrote switchport access vlan 1 and it worked.

here is my new running configuration:

Thank you for the additional information, which is quite helpful. In looking at your pictures I realize that there is a question that Georg or I should have asked much sooner and that question was what gateway (home router) is your router connected to, and what address is your router getting? Now we see that the home router is using network 192.168.1.0. This means that the suggestion that we use 192.168.1.0 for vlan 1 was not correct, and that means that the address translation that we attempted to configure is also not correct. Based on that I suggest that you make these changes in your configuration:

config t

no ip dhcp excluded-address 192.168.1.1
no ip dhcp pool LAN

!

ip dhcp excluded-address 192.168.20.1
ip dhcp pool LAN20
network 192.168.20.0 255.255.255.0
default-router 192.168.20.153
dns-server 8.8.8.8

!

no access-list 1 permit 192.168.1.0 0.0.0.255

access-list 1 permit 192.168.20.0 0.0.0.255

[edit] While I was preparing my response I see that @Georg Pauwen has posted similar suggestions, except there are 2 issues in his DHCP pool, it gives the network as 192.168.1.0 where it should be 192.168.20.0 and it gives default router as 192.168.20.1 where it should be 192.168.20.153

[MattiaBucciarelli79339]

Thank you soooooo much @Richard Burts you helped me a lot. I'm only 15 years old and my father gave me his credentials to use this platform and I feel good this is a wonderful community and very helpful.

Richard do you have an e-mail so when I have a problem like this you could help me directly?

[Richard Burts]

I am glad that we were able to get this worked out. This community is an excellent place to ask questions and to learn about networking. As you get more experience I hope that you will be answering some questions as well as asking questions. In general I prefer to assist with people's issues in the context of the community. There are a couple of reason for that. One is that when issues are raised in the community and solutions are found then many people can benefit from it. Also when questions are asked in the community there is opportunity for multiple people to suggest answers, and frequently having more than one pair of eyes looking at an issue is a big advantage (as in fact for your issue both Georg and I were working on it).

There is a private message function in the community if you want to send me something. And if you really want it you can communicate with me at rcbnetworking@earthlink.net

[Richard Burts]

Thanks for the update. I believe that we are pretty close to getting it to work. First can we verify that the address of the ISP device is 192.168.1.1 and find what address your router is getting? To get those would you post the output of these commands:

show ip interface brief

show arp

Second can you tell us if your PC is getting an IP address using DHCP? If so can you tell us what IP, what mask, and what default gateway?

Third, There are a few commands that @Georg Pauwen suggested that I do not see in your config. So would you do this:

config t

ip nat inside source list 1 interface GigabitEthernet8 overload
ip route 0.0.0.0 0.0.0.0 GigabitEthernet8 dhcp
access-list 1 permit 192.168.1.0 0.0.0.255

quit

and let us know whether it is working with these changes.

[edit] And if it is still not working would you post the output of show ip route

[MattiaBucciarelli79339]

This is my hardware configuration, to access the internet with my Cisco I use my home router, and its ip address is 192.168.1.1

Excuse if you don't understand because I'm italian and my cmd is in italian, this is the ip that I see if I'm connected to the cisco

This is my ip configuration directly connected to my home router not the cisco

Another time thank you for your help, my PC is using dhcp and how you can see from the second image my ip is the preferential, and not given from the cisco and is 169.254.75.220 and the mask 255.255.0.0

My cisco is getting 192.168.1.104

So yes my ISP is 192.168.1.1 (if you mean my home router)

Now I send another reply with some more specs

Hello,

make sure the configuration looks like below. What device is between the Internet and the Cisco router ? It is probably the ISP modem, that device needs a route back to the 192.168.20.0/24 network.
