I have changes some NAT setting on my OPNsense installation - basically redirecting the same ports to different internal IP addresses. My problem is, that some of the rules work (underlined with green) and some not (undelined with red). I can't seem to find what is different in the rule settings.

of course the internal IP addresses work, so 192.168.50.10:80 resolves correctly.
any idea what can be wrong?
			
			
			
				Did you try changing "WAN address" to any since it's coming on the WAN interface?
			
			
			
				ok, it's definitely not an OPNsense problem. when i do nmap 192.168.50.10 i get this result
PORT     STATE SERVICE
22/tcp   open  ssh
25/tcp   open  smtp
111/tcp  open  rpcbind
143/tcp  open  imap
587/tcp  open  submission
993/tcp  open  imaps
1334/tcp open  writesrv
3000/tcp open  ppp
5000/tcp open  upnp
6789/tcp open  ibm-db2-admin
8000/tcp open  http-alt
8080/tcp open  http-proxy
8086/tcp open  d-s-n
8100/tcp open  xprint-server
8180/tcp open  unknown
8181/tcp open  intermapper
8443/tcp open  https-alt
9000/tcp open  cslistener
9091/tcp open  xmltec-xmlmail
strangely the ports 80 and 443 are not listed, even if in a web browser both http://192.168.50.10 and http://192.168.50.10 display the web page hosted on the server

				as i suspected it was at the end unrelated to OPNsense. simply the webserver was not working and my browser was caching its content giving me the impression that it works.
