Multi-Path Room - Add and Manage DNS Resolvers

This article goes over the process to configure and manage a Domain Name System (DNS) resolver in a Multi-Path Room, a Tehama Room with network access type 'Multi-Path'.

See the Multi-Path Room Connectivity User Guide for more information on Multi-Path Rooms.

Overview

Add DNS resolvers to your Room, in order for your Room to convert domain names from your connected networks to IP addresses.

Note: DNS resolvers are optional in a Multi-Path Room. Without any DNS resolvers, the Room will be constrained to provide access for the resources and assets through their DNS server IP addresses.

Each resolver consists of:

• a name, that you give it
• a set of one or more DNS server IP addresses, such as 198.51.100.0.
• a set of one or more domains, such as "example.com"

When a user in any of the Room's Desktops attempts to reach one of the domains in the resolver, the Room will resolve it to one of the servers in the DNS resolver.

Configuring a DNS resolver is as simple as adding an entry consisting of a set of domains and DNS server IPs to your Multi-Path Room:

You can view and edit a resolver entry's details, remove domains from the entry, and delete the entire resolver:

• View DNS Resolver Details
• Edit a DNS Resolver
• Delete a Domain from a DNS Resolver
• Delete a DNS Resolver

Add a DNS Resolver

• Log in to the Tehama Web UI.
• Click on the ROOMS tab.
• Click on the name of the Multi-Path Room you want to connect to add a DNS resolver to. You will see the page for the Room.
• Click on the Room's CONNECTION tab, if you are not already on this tab.
• Click the ADD DNS RESOLVER button. You will see the form for creating a new DNS resolver.
• In the new DNS resolver form, enter the following information:
  • Name - enter a meaningful name for your new DNS resolver.
  • DNS server IP - enter one of the server IPs you want your DNS resolver to resolve the domains to.
    • to enter more server IPs, click Add more to add more fields.
  • Domain - enter one of the domains you want your DNS resolver to resolve to one of the DNS server IPs.
    • to enter more server IPs, click Add more to add more fields.
• Click SAVE. The new entry will show up in the table on the Room's CONNECTIONS page.

View DNS Resolver Details

The details for a DNS resolver include its name, the set of DNS server IPs and the set of domains.

You can view the details of a DNS resolver in your Room as follows:

7. Locate the entry for your DNS resolver.
   • The entry displays the domains that are resolved by the entry.
8. Either click on the name of the DNS resolver, or click on the actions menu (the three vertical dots to the right of the entry) and select "Edit". This displays the EDIT DNS RESOLVER page, which displays the details of the DNS resolver.

(If you do not see the table then you do not have permission to see the DNS resolver info in this Room - and remember that the table is only visible when 'Network Access' is set to 'Multi-Path'.)
7. Locate the entry for your DNS resolver.
   • The entry displays the domains that are resolved by the entry.
8. Click the x by the domain that you wish to delete. A pop-up modal will appear.
   • If there is only one domain in the resolver, the modal will be the DELETE DNS RESOLVER modal. Click DELETE in the modal to delete the entire resolver. The entry for the resolver will disappear from the table.
   • If there is more than one domain in the resolver, the modal will be the DELETE DNS DOMAIN modal. Click DELETE in the modal to delete just that domain from the resolver. The domain will disappear from the entry for the resolver.
