diffent DNS

Goncalo Vieira

Hello.

I´m new to this world of F/Ws.

I have a big doubt.

In my office i can´t access a specified web page ( normal page like news or something). But out of the office i can access this webpage.

Now, in my F/W, if i change the DNS server   to google DNS, then i can access this page.

The problem is that with google dns, i can´t open one app via browser ( very important one).

So my question is, is it possible to have some rule that says if you go to this webpage use google dns.to any other webpages, our internal DNS.

I know it is confusing, but again im new to this.

Thank you all in advance.

B/R to all

    Hi ,

    Thanks for reaching out, and welcome to the Sophos Community! 

    You could configure DNS Request-Routing. 

    Suppose you run your own internal DNS server, this server could be used as an alternate server to resolve DNS queries for a domain you don’t want to be resolved by DNS forwarders. On the Network Services > DNS > Request Routing tab, you can define routes to your own DNS servers.

    To create a DNS request route, proceed as follows:

    1. On the Request-Routing tab, click New DNS Request Route.

      The Add DNS Request Route dialog box opens.

    2. Make the following settings:

      Domain: Enter the domain for which you want to use an alternate DNS server.

      Target servers: Select or add one or more DNS servers to use for resolving the domain entered above. How to add a definition is explained on the Definitions & Users > Network Definitions > Network Definitions page.

      Comment (optional): Add a description or other information.

    3. Click Save.

      The new route appears on the DNS Request Route list and is immediately active.

    To either edit or delete a DNS request route, click the corresponding buttons.

    Hello, 

    Thank you very much for the help.

    May i also say that the DNS server is also the sophos sg125. Does this interfeer with any configuration you mentioned before?

    Once again thank you  !

  • Olá Gonçalo and I add my welcome to that of Harsh above!

    Since you've posted your question in the Network Protection forum, we assume that you haven't activated Web Protection - correct?

    Yes, Harsh's suggestion should work with the UTM as your primary name server for your LAN.  You might want to read through DNS best practice.

    Cheers - Bob
