Can pfsense detect requests and routing to set hostname

sysbitnet

@stephenw10

Do you maybe know what can be a problem why i get

503 Service Unavailable
No server is available to handle this request.

When i try to use another service like Wowza?

Port 80,443 its working perfect, but when i wont to add on the same case other port or services i get the same error

503 Service Unavailable
No server is available to handle this request.

Thank you

stephenw10

I don't know what Wowza is. What exactly have you added? How are you testing it? What do you expect to see?

sysbitnet

@stephenw10

Wowza is a video platform with industry-leading technology that delivers quality live and VOD streaming with integrated CMS, analytics, and more.

But i have the same problem when i try another service, like access on proxmox or any other service who requests another port number but is not port 443 and port 80

Any time i get
503 Service Unavailable
No server is available to handle this request.

stephenw10

Sounds like HAProxy it not configured to use that port so it just returns that 503 error.

sysbitnet

@stephenw10
I agree with you.

How can testing what is the problem only leave this service, for example, i used to test proxmox.

Inside Services / HAProxy / Backend

Name: PM_8006
Mode: active
Name: pm
Forward to: Address+Port
Address: 192.168.100.3
Port: 8006
Encrypt(SSL): yes
SSL checks: yes
And in the Health check method set: basic

How i configure On the Frontend part.

Services / HAProxy / Frontend
Name: PM_Front
External address
Listen address: WAN address (IPv4)
Port: 8006
SSL Offloading: yes

In Access Control lists inside the same
Name: pm
Expression: Host matches
CS: empty
Note: empty
Value: pm.domain.com

In part Actions inside the same

Action Use Backend the name that i set on PM_8006
Condition acl names: the same name that i set in Access Control lists pm

And inside the same Additional certificates select SSL Offloading what i on System / Certificates / Certificates

The same certificate and added inside proxmox, because is letsencrypt wildcard certificate

And when i try to visit https://pm.domain.com:8006/ the result is like this below message.

503 Service Unavailable
No server is available to handle this request.

stephenw10

What do you logged?

Do you see states created on port 8006? For both front and back end?

sysbitnet

This post is deleted!

@stephenw10

I do the same as how i explained in my last post.

I tried many other services that request custom ports and got the same.

503 Service Unavailable
No server is available to handle this request.

stephenw10

So do you see states created?

sysbitnet

Yes, I set.

When i do this just for testing

How can i see if i correctly configured and tried to access it, this is working perfectly.

IP_ProxMox is set localhost IP set inside Firewall / Aliases / IP

When i disable this Port Forward and now testing to login again like https://pm.domain.com:8006 i get this result

503 Service Unavailable
No server is available to handle this request.

If i have a set like this inside HAProxy

But do you see states on port 8006 in Diag > States?

If you mean on Diagnostics / States / States yes this is what i get as a result.

stephenw10

Ok. So what is the LAB interface? What are the IPs there?

I expect to see a port 8006 state on WAN whilst you're testing.

I expect to see a port 8006 state on WAN whilst you're testing.

LAB interface is a local private network, 192.168.100.0./24

stephenw10

Ok so I assume 192.168.100.254 is the LAN interface address.

That state could be the backend on-line check.

If you are trying to connect to it you should also see states on the WAN.

sysbitnet

I just tested with mobile internet and have this result

I get this result with a local private network because i use the same IP and for that reason, i get a local IP

stephenw10

Ok so you do see a state open on the WAN. Do you also see a new state open on LAB when that happens? That's what you would expect to see if HAProxy is opening the backend.

If it isn't then it's probably not trying because it thinks the backend is down.

This is how it configures Backend and Frontend

The web interface can be reached via https://youripaddress:8006 or https://pm.domain.com:8006

When i open Stats FS i see Green for this profile

stephenw10

Oh this is simply the Proxmox webgui. That should work Did you add the Proxmox CA cert to pfSense so it will allow connections?

You should change the backend health-check to https. When that shows as available then proxied requests should do also.
