Configure HAProxy for PC folder access

[viragomann]

@WhiteTiger-IT
You have to let HAproxy insert "/guacamole" into the path:
You can do this with an "http-request set-path" action and enter "/guacamole%[path]" below.

Basically, you can set this rule either in the frontend or in the backend. I'd prefer the backend for this, however.

@viragomann
Even with this change in the backend it doesn't work.
The service is active, but I don't see anything in stats and system logs.
In my opinion the request doesn't even arrive.
Don't I have to set up a NAT?

[viragomann]

@WhiteTiger-IT
No, NAT isn't needed with HAproxy.

Does your backend server log the access?
Can you see something there?

@WhiteTiger-IT said in Configure HAProxy for PC folder access:

Access Control List
Name = ACLName
Expression = Host starts with:
Value = domain.duckdns.org:10101

The port '10101' is not part of the host name.
This ACL will never match any traffic.

[WhiteTiger-IT]

@viragomann
I do not understand.
How is the URL composed? I use:
https://domain.duckdns.org:10101/guacamole
I configured the router to port forward 10101 on its LAN which coincides with the pfSense WAN.
I don't see anything, neither in Stats nor in System Logs/HA-Proxy

Here some snapshots

"/guacamole" is the part, which the backend rule is adding to the requested path. So you should only request "https://domain.duckdns.org:10101" from outside.

Did you also add a firewall rule to allow access to port 10101 on WAN?

If so, is there even any packet arriving? Sniff the WAN traffic to get sure.

Is the backend shown as 'online' in the stats?

[WhiteTiger-IT]

@viragomann
With the setup I posted yesterday, the URL https://domain.duckdns.org:10101 doesn't work .
This is the rule in WAN.

In LAN and DMZ the first rule is everything open.
Nothing is reported in Stats, nor in System Logs-HAProxy, nor in System Logs-Firewall by applying the Pass = 10101 filter.
It's all empty.

@WhiteTiger-IT
Sniff the traffic on WAN as suggested, to ensure if the packets even arrive there.
Possibly your ISP blocks the used port.

Where are you testing from?

[WhiteTiger-IT]

Sorry, but I don't understand you.
I have enabled WAN rule logging.
I'm trying the URL from my PC at home, while with Anydesk I control pfSense remotely.
In System Logs / Firewall / Dynamic View I don't see any traffic related to port 10101 or my home IP.
How do I sniff it? With what package?

The Stats page is completely empty.

Can you explain to me in action the /guacamole%[path] format which I don't understand, what's in [path]?

[stephenw10]

You should see hits on that WAN firewall rule even if HAProxy isn't working at all. If you don't see incoming connections being passed by it then nothing else can work.

Anydesk to a PC inside the remote network?

So you're accessing the remote WAN IP, port 10101 from home, I guess.

How do I sniff it? With what package?

Diagnostic > Packet Capture menu.
Select WAN at interface and enter 10101 into the port filter box.
Start the capture and try to access port 10101 from home.

"path" is a virable used in HAproxy for the origin requested path (the URL part behind the host name).
So you need to exactly enter, what I stated above.

[WhiteTiger-IT]

I removed all configurations, both in pfSense (about HA-Proxy and WAN rules) and the router (about port forwarding), redid them from scratch and restarted both.
Now works. Evidently there was a blockage somewhere.

Before closing the thread, where can I find documentation for the format to use in Actions?

[viragomann]

@WhiteTiger-IT
Generally you can comply with the official HAproxy documentation.
You just need to translate it to the setting possibilities, which you can find in the pfSense web GUI.
