HAProxy noob (SONARR NZBGET RADARR etc…)

[zanesavage]

BTW…

This a more than likely  a dumb question but do I need to do a pass though on the LAN as I did with the WAN side?

By the way this is the site I was initially using as an example:

https://www.edwork.org/2017/06/27/pfsense-with-haproxy/

[PiBa]

No extra firewall rules are needed on lan.

mydomain.com is supposed to give a 503 error as you dont have a acl that checks for that domainname. But firewallrule is okay as it did connect to haproxy.

If you visit sonarr.mydomain.com does the frontend also count some new connection / bytes transfered?

The backends as in the last stats screenshot does not show traffic going to the backends yet.. So your request is not matching the defined acl's yet.

Perhaps try and configure a 'default backend' in the frontend.? That would skip some of the acl's.. Youve got a good domainname in that certificate also.? Perhaps disable the automatically added certificate acl ? (disable checkboxes in cert section)

[zanesavage]

Ok disabled the, "Add ACL for certificate Subject Alternative Names".

The certificate is wildcard certificate *.mydomain.com

The only two options under Frontend "default backend" is sonarr or radarr.

i tried choosing one of them but no bytes/traffic went through in stat. :(

BTW in the Frontend advance section I have:

Use "forwardfor" option - checked

and

In the Advanced pass thru section I have:

redirect scheme https code 301 if !{ ssl_fc }

Not sure if that matters.

[PiBa]

The :443 frontend does show traffic arriving right? Can you post the current latest haproxy.conf?

If there are no acls on the default_backend than basically every request should end up on that default backend..
Unless perhaps if there is a different issue..

Can you fill in the Logging options on settings tab as follows?:
Syslog Host: /var/run/log
Syslog Facility: local0
Syslog Level: Informational
Log Hostname: haproxy

On the frontend enable 'detailed logging'
Save and apply settings..

Then try a request from the browser..

Check under status/packagelogs/haproxy what shows up there.?

[zanesavage]

I removed the default backend as it didn't do anything but here's the status page and log with the default backend I created:

Thanks..hope this helps

[PiBa]

Currently it still reports 'webreverse/<nosrv>' so traffic was not forwarded to a webserver..

Can you add this in "Advanced pass thru" of the frontend:

capture request header Host len 100

And check again what the package logfile shows?</nosrv>

[zanesavage]

Hi,

This is what i got:

May 1 15:55:46 haproxy haproxy[8219]: 10.4.0.10:53016 [01/May/2018:15:55:46.399] webreverse~ webreverse/ <nosrv>-1/-1/-1/-1/0 503 212 - - SC-- 1/1/0/0/0 0/0 {mydomain.com} "GET / HTTP/1.1"

If I type in sonarr.mydomain.com in the browser the log doesn't show anything. If I just type mydomain.com I get the above log event.

[PiBa]

And your really really sure that mydomain.com and sonarr.mydomain.com point to the same IP ?

[zanesavage]

mydomain.com is definitely pointing to my WAN address. I've triple checked it.

sonarr is running on my NAS with an ip of 10.4.0.18 and sonarr being on port 32401. Which matches with the info I put on the backend server.

I must have not configured HAProxy correctly?

I feel like it would be easier to just configure the haproxy.cfg file. Which, I've tried to do but it just gets reset as soon as I launch HAProxy in the pfsense GUI.

[PiBa]

you want requests from a browser to sonarr to be handled by haproxy right? Then the dns record for sonarr must be pointing to the ip where haproxy is listening.. so sonarr.domain.com must be pointing to the wan-address as well.?

basically you would need (imho) would be that there 3 commands:
  ping domain.com
  ping sonarr.domain.com
  ping radarr.domain.com
All would perform the same ping to the wan-ip.

If thats not the case, then in as i currently 'think' the desired state is you would need to reconfigure the DNS records for those names to point to the wanip..

[zanesavage]

HOLY MOTHER OF JESUS!! It worked…well at least radarr did. (see below) ;D

Your last email made me think and I went on my dns and I had not checked off wildcard for mydomain.com.

So sonarr.mydomain.com was not being recognized. So dumb!!!

Thank you so much for your time and especially your patience. I would buy you a beer if you were close by.

Now that I have ports 80 and 443 open…any suggestions on securing them better with pfsense?

[PiBa]

Well.. these services should be available from 'the internet' right? So the ports must be open.. nothing can be done about that part..

:80 doesn't need much securing as it is, as all requests are redirected to :443 anyhow.

You should move the pfSense webgui to a different port, 1443 or something perhaps, and disable the webgui-redirect as that would keep listening on :80 also otherwise.., so that if haproxy for some reason stops running external people wont end up on the webgui if they visit/scan your wan-ip..

You could try and use pfBlocker to limit the country's that can request the pages.. However geo-location aint a exact science. But maybe these items are only for a very limited set of known people.?. In that case you could add client-certificates to use for authentication on haproxy frontend ssl options if its only for yourself being 'on the road' then noone will be able to pass if they dont have the right client cert..

Other than that there aint much i can think of a.t.m. .. Basically you need to trust that the security of the website itself and the separated network segment / hardware its hosted from are secure.. Unless someone else has a great idea and is willing to share that :)

[zanesavage]

Thanks buddy.

I'm almost embarrassed to ask you this seeings you've already helped so much.

How do I get the SSL certificate to work for "In that case you could add client-certificates to use for authentication on haproxy frontend ssl options if its only for yourself being 'on the road' then noone will be able to pass if they dont have the right client cert.."

I have a wildcard certificate *.mydomain.com

Under SSL offloading in my Frontend my certificate shows up and I have it chosen. Underneath are some tick boxes for:

• Add ACL for certificate CommonName. (host header matches the "CN" of the certificate)
• Add ACL for certificate Subject Alternative Names.
• Load certificate ocsp responses for easy certificate validation by the client.

Do I check off all of theses?

[PiBa]

To use client certificates you would first create a CA certificate in pfSense System/CertManager. Then also create a UserCert that is signed by that CA (just select the ca while creating the usercert it will sign it automatically)
(dont try use your real publicly signed cert for this.. it actually make thing less secure..)

Then in haproxy configure the "Client verification CA certificates" select the created CA. And on your client devices download and import the user-certificate into the certificate manager of the OS your using or the browser certificate store..

Now when visiting the website it should ask for the certificate and fail for users that don't have it..

Another thing i just though of that you should do is to specify the ciphers that can be used. use below to generate the cipher settings for haproxy
  https://mozilla.github.io/server-side-tls/ssl-config-generator/
To keep it 'simple' i would stick with the 2 ssl-default-bind-ciphers and ssl-default-bind-options settings and put them on the global tab. That should allow a A rating on ssllabs test iirc..

• OCSP can be enabled it usually makes little difference, but checking the box is easy so why not ;)..
• the acl's for CN and Alternative names, well they dont really add much functionality as your already performing these actions also yourself..

[zanesavage]

Thanks man.

Followed what you said step by step but keep getting:

Errors found while starting haproxy
[ALERT] 122/084430 (51319) : parsing [/var/etc/haproxy_test/haproxy.cfg:29] : 'bind xx.xxx.xxx.xx:443' : unable to load SSL private key from PEM file '/var/etc/haproxy_test/webreverse.pem'.

[ALERT] 122/084430 (51319) : Fatal errors found in configuration.

no matter how many times i create a certificate and CA

[PiBa]

Not sure whats going wrong here..

Perhaps try to give either the CA or the *.domain.com a different name.?.  The /webreverse.pem file itself was working previously.. And there really is no good reason for that to have changed.. Maybe something got broken somewhere.. Try and re-import or perhaps restore a config from before it broke.?. (last 30 configs are under diagnostics/backup/history  in the gui)

[zanesavage]

Thanks for your response.

Unfortunately neither of those two options worked.

I created a few different CA's and user certificates to try with different names; also tried rebooting and then creating a CA/certificate - didn't work.

Reverted to an earlier version of HAProxy, but that didn't work.

I even tried uninstalling HAPROXY and installing HAProxy DEV but no good.

You would happen to have any other ideas?

[PiBa]

This shouldnt be dependant on the version of haproxy used..

unable to load SSL private key from PEM file '/var/etc/haproxy_test/webreverse.pem'.

Can you check the content of that file, does it properly contain both the certificate and the (decrypted) psk ? Of your *.mydomain.com certificate ?

if you download the certificate in the certmanager, does it contain the correct cert and key there as well?

[zanesavage]

I used pfsense Diagnostic Edit file to go:

'/var/etc/haproxy_test/webreverse.pem'

File is empty?

When I checked the certificate it was empty too?

This what I'm doing to create a certificate:

ADD CA certificate
Method - create internal CA (fill out info)
common name - *.mydomain.com

Add certificate
Method - create internal certificate
Certificate authority - same as above from pull down list
fill out info
common name - *.mydomain.com

certificate type - user certificate
add

[PiBa]

Could it be that the selected "Certificate" on the frontend is not pointing to the 'official' signed cert anymore? Re-select and save that one?

(its stored by 'refid', so if you delete a cert and re-create it with the same name it wont be the same cert anymore and it might create a empty file because of that.?.)

Can you check inside the config.xml that the ID's used for the certificate in haproxy really do match those of a certificate?

For example below im using a certificate with refid '5a4004718858f'..

	 <cert><refid>5a4004718858f</refid>

		<type>server</type>
		<caref>57d3118d56766</caref>
		<crt>My-Cert-DATA DATA DATA....</crt>
		<prv>My-PSK-DATA DATA DATA....</prv></cert>
