I have a hp proliant server with ilo and a nginx server. To reach ilo from outside the router I use port 81 and 444 because 80 and 443 are already taken by nginx.

But is there a way that I can somehow redirect the trafic(of a certain domain e.g. ilo.example.com) via nginx to my ilo IP?

HP iLO is an out-of-band server control interface which is used to control the server even when the OS that is installed on it is offline, or completely damages/uninstalled. For this to implement, it has a separate IP address, and, if installed properly, a separate LAN port (shared mode, when it's connected through the OS interfaces is available, but it's a source of many problems). This also means that it has it's own network controller and it's own IP address, so saying 80 and 443 are already taken by nginx you cannot be more wrong, because either your iLO is misconfigured and thus not working, either iLO and your OS have completely different IP addresses and probably VLANs.

  • With "Already taken" I mean that I can't portforwart a port to multiple IPs. But I didn't thought about when the server is off... – Jan Wytze Oct 9 '16 at 18:44
  • You shouldn't portforward anything. You should use plain network setup and public IPs when you need them. Or VPN when you don't. NAT with a numerous portforwards is a clear sign of misdesigned network. – drookie Oct 9 '16 at 18:47
  • And, after all, you can have a publicly accessible WAN VLAN attached to the iLO port. – drookie Oct 9 '16 at 18:49
  • It's probably a dedicated or co-located server with a single IP allotment. – ewwhite Oct 9 '16 at 19:02

This isn't the right way to handle ILO access.
(Do you NEED a public DNS entry for your ILO?)

It should be behind a VPN, if possible. Maybe static NAT if you have the capability and IP space...

However, on the ILO side, the port settings are fully configurable.
