Not really, as that person's question was different from mine.

• I'm looking to forward everything related to domain *.my1stdomain.xyz to nginx proxy manager (I needed to do this as npm works well with Authentik which I use for SSO for some of my apps)
  Whereas HAProxy handles everything related to *.my1stdomain.xyz (I already have this working without issues.

[Bunch]

I've been following this wonderfully crafted tutorial, so "THANK YOU" to the op for this.
Question (I know this might outside the scope of this tutorial):

• If I want HAProxy to handle *.my1stdomain.xyz which would be for specific services (already have this working flawlessly),
  but I would like to forward *.my2nddomain.xyz to nginx proxy manager running on docker so that nginx proxy manager will be used to manage that.

Is that something this setting can help to implement?

If you want nginx to handle TLS of *.my2nddomain.xyz, then the backend of *.my2nddomain.xyz will be in TCP mode.
And you need to set SNI_FRONTEND to something like #176

If you want keeping HAPROXY to handle TLS, you need to change config of nginx to accept proxy protocol, which is really out of scope

Thanks a lot for your input. I'll play around with that and look at #176 as you pointed out.

Great tutorial!

I'm running into a problem accessing the sites within the network after following this tutorial and enabling Cloudflare proxy. Without the Cloudflare proxy I can access the sites both externally and internally but when I enable the Cloudflare proxy I'm unable to access the sites from the internal network.

This post, https://vitobotta.com/2019/12/23/real-ip-haproxy-ingress-behind-cloudflare/, explains how to get the correct IP but I'm not clear on how to implement that in the OPNsense HAProxy implementation. I found a similar question on the forums, https://forum.opnsense.org/index.php?topic=26419.msg127542#msg127542, but there wasn't any answer.

I created a condition with the Cloudflare IPs but I don't know where to go from there, any suggestions?

Sorry, but this is out of scope of this tutorial.

I followed the tutorial and added the necessary config to enable OpenVPN on port 443 but somehow it always keeps sending everything to the SSL_Backend.

Any ideas?

Configure your SNI_frontend like below and it should work.

I think it matches your example but I still get errors in the haproxy log:

I looked a bit further and now I do see entries appearing in the OpenVPN logs so I will check those out first.

hi guys,

I am trying to setup a SSO using keycloak, openLDAP and other providers. I have it all working locally but now wanting to communicate to the LDAP server via ldap://ldap.mydomain.com instead of ldap://192.168.1.104:1389.

The only difference that i have tried is changing the mode on the backend server from HTTP to TCP. I just recieve a timeout error when testing.

Thanks @TheHellSite for an awesome tutorial and support to us all with OPNsense & HAproxy
I have a perfectly working HAproxy thanks to you with dynamic DNS, LetsEncrypt and multiple reverse proxied sites.

However, I have not changed the default port for OPNsense away from 443

I have three externally accessible sites all via my single public IP, which are directed to three different backend servers using HAproxy
These public urls are specified in the 'listening addresses' of my public service using their ww.example.com:443 format. I have not specified a broad 0.0.0.0:443 for example

What's your view on this setup and its possible conflict with the OPNsesne webserver. Am I correct to specify the url's and therefore HAproxy is only listening for these and not the url or IP for OPNsense?

Thanks for any advice

[phib3r]

My config is working great thanks to this post ! I do have a quick question that you may be able to expand on - requiring client certificates from a specific sub domain. I have tried out a few things, but all that seems to happen is that all the sub domains request client certs. I have tried to create a new public https frontend and have that look up from a different mapping file - but all that seems to happen is that the original https front end just now requires client certs. I would post my config - but it is currently working and to the letter what you have posted with just some more sub domains added. Any help or pointing in the right direction would be fantastic.

[phib3r]

To the LDAP question above might be that LDAP is using UDP and not tcp

[phib3r]

Might be - sorry

Could someone say why my SSH service points everytime to the Router and doesn't split to ssh, ssh.kvm, ssh.server, ssh.nas?

My map file looks like

Code Select Expand


#public access subdomains
flood WEBSERVER_backend
kvm KVM_backend
nas WEBSERVER_backend
grafana WEBSERVER_backend
phpmyadmin WEBSERVER_backend
speedtestserver WEBERSERVER_backend
cloud NAS_backend
dav NAS_backend
stefan NAS_backend
mopidy MOPIDY_backend
git WEBSERVER_backend
chat MATRIX_backend
admin WEBSERVER_backend
sync SYNC_backend
ssh.nas NAS_SSH_backend
ssh.server SERVER_SSH_backend
ssh ROUTER_SSH_backend
ssh.kvm KVM_SSH_backend


Is a frontend for port 22 necessary?
Thanks for advices.

Just think a little bit deeper:
I'm afraid SSH_frontend will never able to bind if your router is 192.168.1.1
As it always using port 22, you will never able to take port 22 with HAProxy.
Thus, everything related to SSH_frontend will never work until you change SSH of your router to different port
