I have the cisco 2921 configured with 1 trunk port, on which are: LAN, WAN
So, I can't ping from router any resources with domain name, like google.com, cisco.com
but I can ping them's IP and it's success.
What can be with configuratuion, when ping to IP - success, but to domain name - fails ?
There are a couple of things to look at. First, can you ping your dns provider in the image? Also, have you tried changing the primary to another one of google's addresses? (126.96.36.199). Try replacing your 77.232.x.x address with 188.8.131.52 and see if that helps. Do you have any acl's on the wan interface that could be blocking udp traffic for dns or a firewall?

I found, what the error was on 2921.
But know I have an other question.
I have this cisco 2921, and first-connected 2504 with 23 airports.
When I'm in Wi-Fi location, I connect to network, accept the IP, Subnet Mask, GW, DNS..but internet doesn't work.
What can this be ?
Can be this some problems with NAT or anything else.
