I have a question.
After installing Calibre and running the content-server, I configered port-forwarding in my router.
Most things are working correctly, but not from outside my home network. I looked over similar problems in this forum, but could not find a solution.
  • The calibre-page is working from another computer within my home network on the internal ip-address of the pc where calibre content-server is running.
  • The calibre-page is also working from within my home network on the external ip-address. (I followed the advise to go to whatismyip.com).
  • The calibre-page is not working from outside (VPN connection/appserver at my work); get an error "unable to connect".
  • I can ping my external ip-address from my work and getting a reply.

My conclusions so far:
- the firewalls of the server-pc is not troubeling anything.
- port forwarding works, at least from within my home network.

My question: Perhaps it is the firewall of my work, that keeps me from getting a response, or can it be something else?
1) A Ping of you outside address from work, is your router answering ( do you really want that security weakness, however convenient?) .
2) Ask your IT staff if they block the port you chose to use (as the incoming on your home router) (NB they don't have to match Outside to Inside other than be correct. PublicIPort12345 ->Calibre_serverIP:8080).
3) Your ISP may be blocking at a different level (that did not prevent a close-in level loopback)
