Note the following:

  • If you have a server with more than one network adapter, you typically enter one default gateway. With ISA Server, the default gateway is usually configured on the external network adapter.

  • If there are additional internal networks that are connected using a router, add required routes to ISA Server prior to beginning the installation.

  • Make sure that routing is properly configured before installing ISA Server 2006.

  • DNS servers in most cases should be configured on the internal network adapter and should point to an internal DNS server. Confirm that the name resolution is working properly.

  • Depending on your configuration, you might have to create an access rule to allow DNS queries from the Internal network.

  • If routing and name resolution are not working properly and ISA Server 2006 is installed, it will be difficult to troubleshoot the cause of the problem.
