How can I route requests to a server on an internal lan through an external dns?
Posted on 2004-04-27
We have a 10.x.x.x internal scope running trhough a cisco pix firewall to a 2600 router to the internet. We have web applications running from our website and from two other servers on our internal lan. If using a dns server external to our lan, we can resolve the internal web through an alias command in the pix. Unfortunately, I cannot access the other two servers which are usually access through ip address. Access from the outside in works fine, but we cannot resolve the external ip address back to the internal nat in the pix. All other sites are accessible except the two that need resolution to the ip address. A Cisco TAC engineer said that a static route may need to be put in for the particular ip address at the router. Does this sound like a possibility? Any ideas? We have created a workaround by providing two seperate links on our web... one to the inside ip address and one to the outside but would like to be able to allow the inside scope to resolve to the same link as the external.
