Hi, it is possible to achieve this scenario with opnsense, nginx and acme plugins.
I have a router with opensense installed WAN port has a public IPv4. LAN is 192.168.1.1/24 subnet.
I have a dns record subdomain.mydomain.tld pointing to WAN addres.
I have configure acme plugin to generate certificates. Certificates are generating correctly.
Now I am messed up with nginx configuration. I have a microsoft iis web server in local lan with ip 192.168.1.100 There are some websites/services runing .
http://192.168.1.100:80/service1
http://192.168.1.100:80/service2
http://192.168.1.100:80/service3
Now I want to connect from internet to this server using nginx reverse proxy in this way:
1. Redirect http/https trafic with domain name to service1 with use of acme certificate
http://subdomain.mydomain.tld/ or https://subdomain.mydomain.tld/ -> http://192.168.1.100:80/service1
2. Redirect http trafic to public WAN ip without domain name to service2 and service3
http://publicIPv4/service2 -> http://192.168.1.100:80/service2
http://publicIPv4/service3 -> http://192.168.1.100:80/service3
http://publicIPv4/whatever -> http://192.168.1.100:80/whatever
I was only able to partially configure it in nginx plugin:
1. configured upstream and upstream server to point 192.168.1.100
2. configured locations
Description: subdomain.mydomain.tld
Url Pattern: /service1
Match type: Case Insensitive Match ("~*")
Force HTTPs: 1
Upstream server: 192.168.1.100
Description: publicIPv4
Url Pattern: /
Match type: none
Force HTTPs: 0
Upstream server: 192.168.1.100
3. configured 2 http servers
Name: subdomain.mydomain.tld
Certificete: subdomain.mydomain.tld
Location: subdomain.mydomain.tld
Name: publicIPv4
Certificate: none
Location: publicIPv4
With this configuration http://publicIPv4/whatever working like I want.
https://subdomain.mydomain.tld/service1 working.
But how can I https://subdomain.mydomain.tld/ redirect to http://192.168.1.100:80/service1
Thanks for the advice on the correct configuration.
Hi!
if I understand correctly that everything works except for redirecting the "fqdn" requests to IIS with a "service1" prefix, then you can try to create a "/"-pattern location with a "/service1/" Path Prefix and assign this location to "subdomain.mydomain.tld" server
