i have an problem with my new Cisco 876 Router. I configured port forwarding to access internal network devices from the internet (dyndns adress). This works good from external but with my old Fritzbox I was able to connect to this internal devices from the same internal network with the dyndns adress.
So here is a short review for this:
DYNDNS Adress port tcp 80 - > 192.168.0.80 tcp port 80
from extern it works but with source adress example 192.168.0.20 to destination DYNDNS adress tcp 80 (maps to 192.168.0.80 tcp 80 ) it doesn't work.
Is ther any trick in the config of cisco to let this scenario work?
this is called hairpinning and is not supported on enterprise router models but you can use dns doctoring which is the default on these routers by accessing the ressource from inside by fqdn instead of IP address.
I have some laptops that should get access from outside and inside the network. So I don't want to add double bookmarks for the same website. For not IT specialists, that use this websites too, this is a little confusing to use two bookmarks for the same website.
So how I can solve this with dns? What configuration is needed on the cisco router or on the dns server?
