How
to publish the DNS Server on ISA
1. Run ISA Server management.
2. Click Firewall Policy.
3. On the Firewall Policy task pane under the Tasks tab in the left pane,
click Create New Server Publishing Rule to start the New Server Publishing
Rule Wizard.
4. On the Welcome page of the wizard, type a name for the rule, for example
PublishDNS, and then click Next.
5. On the Select Server page, type the IP address for the DNS server, and
then click Next.
6. On the Select Protocol page, select DNS Server, and then click Next.
7. On the IP Addresses page, select the network on which ISA Server
will listen for requests. Because you want to receive name resolution
requests from the Internet, select External, and then click Next.
8. On the Completing the New Server Publishing Rule Wizard page, verify that
you have configured the rule correctly, and then click Finish.
9. In the ISA Server details pane, click Apply to apply the changes you have
made.
10. You must also update your name server record for your Internet domain to
point to the external IP address of the ISA Server computer, for example
isa.chicagotech.net.
Note: There is an access rule in the ISA Server system policy that allows
the DNS protocol from the ISA Server computer to all networks. This rule is
enabled by default when you install ISA Server, so you do not have to create
this rule. If you have an issue with DNS on ISA, you may double check it.
