I hope anyone can help me with this
The setup: We have a few hosting servers. There are webpages of our clients. We also have a backup unit with web-based control interface. The backup unit is not on public IP. It's hidden in intranet - all our servers and the backup unit are connected together in an internal 10.0.0.0 network.
My question is: How can I access the web interface on the bakcup unit from internet?
Scheme: Internet -> (public IP) -> Server -> (intranet 10.0.0.0) Backup unit
All servers are running Debian if that's any help. I can't just forward port 80 because servers are running webpages. How to do this?
Many thanks!
