Problems with NAT configuration

z0mmer3131

Level 1

Hello,

Could you please help me. I just received 2911 router and I have problems with configuring NAT on it. I want to connect port GE0/1 to office LAN with internet and I set up the interface "ip dhcp" so it could catch IP address from another router with internet access. GE0/2 goes to LAN without internet. I want to connect LAN from GE0/2 to LAN GE0/1 with internet, but NAT doesnt work. Could you please tell me what is the problem?

Below copied show run

Thank you

Andrey,


This community does not provide technical support and is not staffed with technical support experts. I recommend you post this and future technical support questions to the Cisco Support Community (https://supportforums.cisco.com/index.jspa) where our Cisco technical support experts provide debugging assistance. Another option is to open a ticket with the Cisco Technical Assistance Center (www.cisco.com/go/support) to get expert debugging assistance.

We do encourage you to participate in the Cisco Collaboration Community and to also join our Cisco Collaboration User Group program!  In the community, we encourage your discussion/sharing around collaboration topics and Cisco Collaboration Solutions, including business and IT requirements, industry trends, process, culture/organization issues, how collaboration can be used to transform businesses, vendor selection, adoption, training, architecture, licensing, and product features/functionality. If you are a customer or partner, you can also join the user group program to be eligible for member-only events and influence product direction.

We hope to hear from you again,
