Facing issue with wireless users. Domain lookup is not happening for them, thus causing no internet.
We configured IAP internal DHCP server along with google public DNS. Users are getting correct IP and able to ping 126.96.36.199 but not able to resolve the domain name.
When I am connecting to the wired port with same IP configuration I am able to do #nslookup with success.
I have done dns debug for the users and its saying "response code: refused(5)" , nothing is blocking in Firewall.
Attached is the log file.
Is it possible that you have "internal-domains" set? http://www.arubanetworks.com/techdocs/Instant_42_WebHelp/InstantWebHelp.htm?_ga=1.43038629.1615771646.1440445030#CLI_commands/internal-domains.htm?Highlight=domain
Do you have a toplogy diagram?
How are these users getting to the internet?
What is the client default gateway?
We are missing detail here.
Please configure the same DNS server for the IAP as well & then test the client connectivity.
IAP proxies all DNS requests for the clients in this mode.
If you configure an asterisk (*) instead of a domain name in the enterprise domain list, all DNS requests areforwarded to the default DNS server of the client. If you want all DNS requests to be processed by the DNS server of the client, configure an asterisk (*) in the enterprise domain setting.
So, we have the following options:
1. Configure the DNS server to be same for IAP & Client.
2. In case we do not have DNS configured for the IAP, then configure an asterisk (*) in the enterprise
domain settings which will allow all the DNS request to be processed by the DNS server of the client.
Thank you for confirming that things are workin as expected.
