How does DNS resolve to external IP address?
That is, internally the DNS client does resolve to the external address, however, when the client software attempts to contact the external IP address the firewall does its magic and redirects them to the internal address. It beats the administrative burden of maintaining an internal phantom copy of your external DNS space.
How to re-direct external IP to internal IP address?
If the client is trying to connect to an IP address (8.8.8.8 for example) setting a DNS entry for 8.8.8.8 in your DNS pointing to 10.0.0.3 will not re-route your traffic to 10.0.0.3 – why? Because DNS is not used if the system already has the IP address. You should use NAT router that can handle the packets from external to the internal IP address.
How to properly redirect an address to an internal address?
Example: We want “note.companyname.com” to redirect to: 192.168.20.120. I tried to setup some aliases in DNS, but they don’t appear to work (meaning when I ping “note.companyname.com” the IP that comes back is our external address and not the internal one. So what might I have done wrong? Where is the correct location in DNS and method to add this?
Why is my internal DNS server ignoring my Ping?
So here’s the question – doesn’t (or shouldn’t) our internal DNS server be resolving this ping request for note.companyname.com with it’s INTERNAL list before THEN going to check it’s EXTERNAL list (cache)? It seems as though it’s ignoring the internal entry. How can I tell if this is the issue and more importantly, how do I fix this?
How to point external name to internal IP address?
Verify your account to enable IT peers to see that you are a professional. If the service is running on an internal (private managed IP) then you need the router to do a NAT to route packets from the outside to that server. If it’s a web service you’d NAT incoming requests from port 80 to that servers internal IP address.
What’s the difference between internal DNS and external DNS?
The static NAT is setup in the firewall, external address responds just fine. My issue is, our internal DNS is sitename.local whereas our external DNS is sitename.org When I access the site internally it resolves with the sitename.local, but I can still access the webpage, no real issue there.
Why does my DNS resolve to sitename.local?
When I access the site internally it resolves with the sitename.local, but I can still access the webpage, no real issue there. The problem is externally when I access the webpage either by public DNS name or public IP, it resolves to the sitename.local, which obviously doesn’t work for public users.
