Access internet - dns

[aoun.ameur1]

Hi all,

I have an issue when connect from internal network to internet via ASA5515-x

I can't open web page.

Otherwise, i have configured the default router, the nat translation and the dns service on the firewall.

dns domain-lookup INTERNET
dns domain-lookup LAN
dns server-group DefaultDNS
name-server 8.8.8.8
name-server 4.2.2.2
domain-name *****.local

ping to 8.8.8.8 is working

from my pc , i can't access internet until i put 8.8.8.8 as dns secondary 

an i fix this issue from the ASA without putting 8.8.8.8 on the card of my pc ?

This seems to be a DHCP issue that is if the PC uses DHCP.  If so then then the DHCP server is not issuing a DNS server when handing out DHCP.  If it is a static IP you must configure a DNS server to be able to resolve URLs.

Thank you Marius for replying.

it is a static IP configuration, so I need to configure a DNS Server as you say. The configuration of DNS Server will be in ASA or just a simple DNS Server (expl: from Microsoft with active directory roles) ?

You need to configure DNS on the PC if you want to be able to browse the internet.  Configuring the ASA with a DNS just means that the ASA will be able to resolve URLs aswell.  Other than that, if you will use the asa as a DHCP server then you need to also configure the dhcp service to hand out an IP that the client PCs will use for DNS resolution.

thank you Marius,

The problem was resolved. I correct forwarder on DNS (Active Directory) and adding 8.8.8.8 as another Forwarder.

Thannks a lot !!
