Web Proxy Filtering and Caching / Homeassistant behind nginx proxy not working

« on: February 25, 2024, 04:05:34 pm »

Hi, I try to run Homeassistant (running on port 8123) behind the nginx plugin.
in homeassistant configuration.yaml in section http: I have the entries use_x_forwarded_for: true and trusted_proxies: <lan address of opnsense>

in nginx logs http access, I get error status codes 304 400 499

according to
https://community.home-assistant.io/t/reverse-proxy-using-nginx/196954

there are headers needed like:
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;

but I can not get it to run.

Is there a way to set the headers via the opnsense web gui?

Hi,
habe ähnliche konfig. FritzBox (FB) und dahinter eine esxi vm mit opnsense.
In der FB habe ich die opnsense ip als exposed host eingetragen. Die FB filtert somit nicht. das soll alles opnsense machen. dyndns macht ausschließlich opnsense. Ich habe noch in der dmz (2.eth anschluß) einen mailserver, hängen, der smtp anbietet sowie eine weboberfläche zum emial handling.
Dafür verwende ich nginx proxy. haproxy habe ich nicht installiert. nginx hört auf port 443 und leitet das zum port 80 des mailservers. das zertifikat handling macht somit ausschließlich nginx auf der opnsense mit dem acme client.
ich habe mehrere zertifakte für webmail.mydomain.xx ftp.mydomain.xx usw. nginx proxy kann dann anhand dieser domains auf die enzelnen upstream server in der dmz verzweigen.

in der firewall alias section:
definiere einen alias namen webaccess mit dem content 80 und 443
weitere aliase, je nach Bedarf e.g. für ftp ical usw.

in der firewall rules WAN section jeweils einen entry erzeugen:
protocol:IP4 Source:* Port:* Destination:WAN address Port:webaccess Gateway:* Schedule:*

NAT brauchst du für die einzelnen nginx upstream server nicht. Brauchst du nur für services die den nginx proxy nicht verwenden. e.g. ftp

my last automatic cert renewal was executed last December. After upgrading opensense, (couldnt remeber when), cert renewals are failing. I looks like that the lighthtpd process running on port 43580 respond with Forbidden.

1. test on opensense root cli:
# fetch http://localhost:43580
fetch: http://localhost:43580: Forbidden

2. test on desktop firefox, calling
http://<internal IP of my openses>/.well-known/acme-challenge/XXXXidXXXXX....
results in Forbidden


sockstat -4 -l

I have the same problem, if I'm connected to my Wlan behind opensense.
Unbound DNS: Blocklist /  Force SafeSearch is OFF
Connecting to my RouterWlan (it's my guest wlan) I have no issue.

/var/log/rspamd # cat rspamd.log | grep antivirus   shows nothing
/var/log/rspamd # cat rspamd.log | grep clamav
shows this single entry:
2022-12-10 09:25:07 #5307(normal) <0c1b62>; lua; clamav.lua:131: clamav: message or mime_part is clean

but the id <0c1b62> is not the id from the message/mail with the eicar attachment <48af5d>

thanks, I've created this directory and placed a file 'test' into it
IPaddr is the internal IP of my fw. service has started.

I logged into a rpi, which has an ip of the internal net.
follwing test:
tftp <ip_of_int_fw>
tftp> status
Connected to <ip_of_int_fw>
Mode: netascii Verbose: off Tracing: off
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds
tftp> get test
Transfer timed out.
tftp> quit

in opnsense logfile:
tftpd: read(ack): Connection refused

fw rule: pls. see attachment

I did the change (uncomment) in /usr/local/opnsense/service/templates/OPNsense/Rspamd/antivirus.conf
reapply rspamd config in gui

send an email with eicar attachment, rspamd logs the entry, but no entry (message or mime_part is clean) in rspam log
