Cisco Router - Accessing own external IP internaly

  • 772

Background:

We are a small IT company that doesnt have any official cisco training that have picked up a few cisco routers than we have been able to bluff through except for this problem.

The issue:

When on the internal network behind the cisco router if you try to access a service from our network using the external IP address it will not connect.

An Example:

If we try to visit the company website which is internally hosted then it will give an error saying it cannot estrablish a connection to the webserver.

  2. Another possible solution would be to have different internal and external DNS servers. With the external DNS having a minimal amount of published information and the internal servers having a full view. When you do this you could make the service have the internal address on the internal DNS and the external address on the external DNS.
