Froxlor hinter Firewall


Question

Hallo zusammen,

ich kämpfe momentan mit der SSL Konfiguration von meinem Froxlor-Server.

Bedauerlicherweise befindet sich der Webserver hinter einer Firewall und hat eine private IP Adresse zugewiesen bekommen. 
Die Firewall leitet entsprechend den Traffic von außerhalb auf den Server weiter (HTTP ist das alles kein Problem).

Nun habe ich vorhin SSL aktivieren wollen und hierzu kann ich leider keine private IP Adresse eintragen (lässt Froxlor nicht zu).
Entsprechend habe ich die public IP eingetragen, was aber auch nicht funktioniert, da durch das NAT der Firewall die private IP angesprochen wird - somit funktioniert dies nicht.

Habt ihr eine Idee, wie man das umbauen kann?

An sich brauche ich nur die private IP Adresse als SSL Adresse eintragen - vermute aber, dass dadurch Let's Encrypt auch nicht mehr richtig laufen wird.

Viele Grüße

Michael

PS: Ein 1:1 NAT wäre noch eine Möglichkeit, da ich die Public IP aber für diverse Server verwende, fällt das auch raus. Müsste dann eine neue Public IP kaufen, welche ich dann mit einem 1:1 NAT auf den Webserver laufen lasse (wäre noch eine Möglichkeit)

Ich kenne dein Firewall-System jetzt nicht, aber in einer Multiserver-Umgebung mit Loadbalancer z.B. funktioniert das wunderbar. Eine Firewall ist eigentlich kein Router der NAT'ed. Bitte beschreibe dein Setup mal etwas genauer und welche dienste da wo was machen und was du bezwecken willst. Wenn du nur eine public IP hast und die für mehrere GLEICHE Dienste nutzen willst wird es schwer, dann muss der Loadbalancer/Firewall/Einstiegspunkt/wasauchimmer entsprechend nach vhost/SNI-like verteilen...das klappt aber so nicht für alle Dienste - also, es wäre hilfreich zu wissen was du da genau vorhast und was vorhanden ist und wie der aufbau ist

      Hello,
      I seem to be getting this error when the cron runs:
      [debug] System certificate file "/etc/ssl/froxlor-custom/xxx.tld.crt" does not seem to exist. Disabling SSL-vhost for "xxx.tld"
      Froxlor VirtualHost is enabled, along with SSL generation but it seems like it's being generated on acme's folder and not copied over to /etc/ssl/froxlor-custom/, anyone has any clues?
       
      Many thanks,

      Hi,
      I'm just wondering what the difference is between the following 2 folders:
      Why is froxlor installing acme.sh cron everytime it runs at 3am everyday especially since the 5-min let's encrypt froxlor cron is already in place? Also, all my db config points to /etc/ssl/froxlor-custom for the domains and all keys/certificates inside that folder have a different md5 from the ones under /root/.acme.sh/, so I'm wondering what's with the mismatch? Are we updating certificates for domains twice?
       
      If anyone can shed some more light on this, it will be very much appreciated.
       
      Many thanks!

      Hi all,
       
      I am new to Froxlor and so far enjoying it but unsure how to use it and have a few questions.
      I have pointed an A record from my domain provider to the server and am able to access the web panel using the domain but my FTP client (filezilla) can't find it. Does it have a mail server built in or do I have to configure that. Can I use it as a nameserver? What ports does it  need to function (so I can setup my firewall) Thanks in advance for all your help.

      Hi,
      I have a domain equipped with a certificate from LE. The cert is valid another 2 months. Now I added a domain as an alias of the existing domain, but the certificate isn't updated to have the new domain as its SAN.
      How do I trigger getting a new and updated certificate? Should I delete the existing one?
      Thanks for helping out.
       
      Peter
