Thanks for this post. I had ISC dhcp working fine with Ipv6 but I saw that it was advised to go to Dnsmasq. After a week bad DNS (some sites like this forum even got 'timed out') I switched back to the normal Router advertisements and everything worked instantly.

The bottom line for missing traffic is that it's not seen by firewall, tcpdump or netmap.

I'd say the main problem with Tailscale on FreeBSD is here: https://github.com/tailscale/tailscale/issues/5573

There are some weird hacks with exporting TS_DEBUG_NETSTACK_SUBNETS=0 suggested, did not look into it. As it as, I'd say assigning the interfaces is absolutely pointless, these cannot be treated the usual way, firewalled via pf nor can Tailscale be used for site-to-site VPNs on BSD.

Thx, that seems to be the issue. The work around looks difficult and hacky. Maybe i go back  to wireguard again..

I was wondering if your setup with a tailscale interface is working as you intended? I have a tailscale setup working but firewall rules are not working. I see no bytes flowing through the tailscale interface in traffic reporting. What i would like to do to is protecting the tailscale interface with zenarmor.

I had the same notifications the last couple of days (after upgrading zenarmor?) I have run zenarmor for almost a year and never had this notification. Don't know either how to troubleshoot

Thx to the excellent tutorial of @TheHellSite (https://forum.opnsense.org/index.php?topic=23339.225) I have HAproxy working.

I have one service I would like to be entered only through Authelia, to enable 2FA. I see a guide for pfsense (https://dkict.com/pfsense-haproxy-authelia/) but I cannot get it to work in OPNsense

I have the needed lua scripts in place but I cannot find a place to enter the needed configuration for the backend service like "acl remote_user_exist var(req.auth_response_header.remote_user) -m found"

Anyone has this kind of setup working and would like to help me

Strange but 503 error appear to me as well.
I tested with apache,nodejs,wamp nothing worked. They i try to redirect to my switch to see if my windows is not the problem... but nope.
DynamicDNS is configured and working fine,
All gui redirections disabled and opnsense gui port changed.
Added firewall rule to WAN , and no additional LAN rules added ( it's almost fresh install )
Acme - generated fine cert via dns. ( 2/4/2023, 7:23:39 PM   OK   2/4/2023, 7:23:40 PM )

Tested from external network via smartphone on cellular data.

One thing is that i am using proxmox to virtualize opnsense as "routerOnStick/Forbidden Router" and i pass two ports from quad NIC on promox-server as LAN/WAN for opnsense , and lan is going to dumb switch that transfer vlans/lan to rest of my house , so far not a single problem with that but maybe just maybe..

I see also in your backend for XKP SSL is checked. Could you try by unchecking the SSL?

I do not understand what you mean by serving SSL on the HTTP port. I think I followed your tutorial to the letter (except for using a Let's encrypt certificate by using cloudflare API from my domain)

It is dangerous to do things like exposing services to the internet when you don't even understand this simple question from me!  :-\

Read step 9 of my FAQ. You should also really read the explanation of the "SSL checkbox" in the server setup page!
I bet you are not accessing your services by their local ip using HTTPS you are likely accessing them using HTTP.

Yes that was the problem...

Thx you @TheHellSite for this tutorial. Unfortunately I cannot get it to work. I always get a "503 service unavaible status"

If I use the internal addresses of the websites (192.168.2.40:8083 for example) I can login. But using the website.domain.com I get a 503 error. In the logs I see that the client is accessing the public Ip on port 443.

Please give further details on what is and whet it is not working.

Are you able to access your services via their domain name from a device outside of your local network?

Did you configure the DNS overrides for the local clients?

Also your Bitwarden server seems to be misconfigured are you sure it is serving SSL on the HTTP port? Also verify this for your other service.

Well, nothing is working, both not from within the local network and also not from outside.

I did configure the DNS override, but I first try to access the services from my mobile device.

I do not understand what you mean by serving SSL on the HTTP port. I think I followed your tutorial to the letter (except for using a Let's encrypt certificate by using cloudflare API from my domain)

Edit: I found it, I needed to uncheck the SSL tickbox in the real server settings. In your tutorial you have it checked and I saw in this forum someone else who had the same problem...

Thx alot!!
