Router config help

Bodazephyr
Level 1
Level 1

I am new to cisco routing, I took a CCNA course 10 years ago but forgot most I had learned. I am currently relearning and trying to configure an unconfigured router. It is an 891fw router and I am having trouble accessing anything inside OR outside the lan. First what are the basics needed to have a basic working router. Secondly if you can look at my config and let me know what I am missing.

Hello,

 

your config is almost complete. I have made a few changes (marked in bold) that should enable your clients to get Internet access:

Yes! That was it from what i see its had to do with the access list, can you tell me what i did wrong though? 

 

From what i see it was pointing to wrong access list? And something with dhcp

Hello,

 

in the original post, you were referring to access list 'nat-acl' which I didn't see in the configuration at all...

I take that back I can ping devices on lan just not out lan. and no internet access

Did you apply the configuration changes I posted ?

Hello Bodazephyr,

 

There is one thing I noticed in your configuration. I don't think you can use VLAN interface for dhcp allocation. Vlan interface are just for management propose. You should configure the dhcp interface to one of the physical interfaces. That must be the problem why you are having problem accessing anything inside or outside the LAN.

Well my dhcp is working and with the other reply i got the internet working. I do like to listen to advice though can anyone confirm im not supposed to use dhcp on the vlan? 

Hello,

 

DHCP with VLAN interfaces is no problem, actually, it is quite common to use it in that way...

Thank you again Georg!
