General Discussion / Unbound DNS - Register DHCP leases

« on: January 26, 2021, 06:56:18 am »

Is there any place to see the dynamic DNS added via DHCP leases in Unbound DNS?  I created a static reservation and now Unbound has both the old and new IP.  I can't see what all the dynamic entries are or how to delete one.

19.1 Legacy Series / Re: WAN admin - Firewall Allow but Blocked

« on: April 18, 2019, 09:15:29 pm »

I'm not sure if this is normal, but I got it to work and I'll explain. 
My WAN was set with an IP of 10.x.x.1 and my LAN 192.168.x.1.  I disabled the option that would block private or bogon networks.  I allowed any any to access 10.x.x.1 any.  I was not able to connect to the web admin unless I went to the console and did a 'service pf onestop'.

I changed the WAN IP to a internet facing ip range and put it online.  Now it works without issue and I've tightened up the source ip and destination port in the rules.  Why would it not work with a 10.x.x.x assignment?  I was accessing it from that network.  Anyway.. figured I'd post in case others had a similar issue.

19.1 Legacy Series / WAN admin - Firewall Allow but Blocked

« on: April 17, 2019, 05:25:34 am »

I have a situation where I need to enable web administration on the WAN.  I've done this before without issues.  Go to console, shut down packet filter, set WAN firewall to allow my source IP to destination WAN address port 443.  Restart pf.

I just installed a new install of opnsense yesterday, but I can't get this to work.  I'm able to stop pf from a remote console and then access the WAN web admin, but after adding the WAN firewall rule (even to the point of ANY ANY), when pf restarts, I'm blocked by the default fw block rule.  Any thoughts why this would happen?

I know best practice is to vpn or something and access via the lan (and I'll get to that), but I need this to work on the wan first to set everything up properly.  Also, web admin is enabled for all interfaces.

It is enabled when you enable HTTPS as well as you can configure it under security headers.

fabian, can you point me to what I need to select to disable HSTS under security headers?  I see a couple options, but they seem more like configurations for HSTS, not on enabling or disabling it.  It's not clear how to do this unless you're speaking of editing the nginx.cfg directly - thanks.

Here is the error in the log for trying to delete the IP ACL.  Running 18.7.10_4

It is not apparent that the little refresh icon is suppose to save the configuration.  If the button that says "Save changes" doesn't save the changes, why would a user click on a refresh icon that has no tooltip.  It would be really helpful if you made the Save changes button actually update the configuration.

Personally, I think HSTS should be off by default.  It's too easy to mess up when testing and you're unable to get yourself corrected without digging into your browser.  But if you're going to have it enabled, I think it would be very helpful to make it easy to disable.  It's clearly labeled in the System:Settings:Administration "Enable HTTP Strict Transport Security" but I can't find it in nginx.  There is a place in the Location that says "Force HTTPS" but disabling it doesn't appear to change HSTS, nor does the option in HTTP Server that says "HTTPS Only".  It makes sense that it might be in the Security Headers section, but I don't see where it's listed.  In fact, turning off the Security Policy has no effect on HSTS.  There is the option for "Strict Transport Security: Time" and "Strict Transport Security: Include Subdomains", but nothing to actually turn it off.  I guess I could set Time to 0?  I could manually edit the nginx.cfg, but I want this to be able to survive config changes via the gui and opnsense updates.

fabian, how do you turn off HSTS Strict-Transport-Security for nginx?  I've tried several things, but can't seem to find the option to disable this.

Seems you can't delete an IP ACL once it's created.  It would also be nice if the IP ACL could utilize the Firewall Alias groups.

@fabian I figured out the issue and I'd suggest some changes to the plugin.

When you're on one of the settings, such as HTTP Server, and click "Save Changes" it doesn't actually save anything.  When you restart nginx, you still have the same settings.  This can be verified by looking at the nginx.cfg.  You have to go the General Settings and click Apply before they'll actually be saved.  This is why I was ripping my hair out as it is assumed that Save Changes and a service restart should apply the new settings - it does not.  Not until you click Apply on the General Settings.  If it requires an Apply afterward, it should do the banner like on the firewall or something or prompt the user if they want to apply the settings.

I got http working using port 8888 on the "http server", but not 80.  Tried doing https on 4444, but it's not working either.  It doesn't seem to be restarting nginx properly as under Firewall Sockets, it still shows it bound to port 8888, even though I've changed it and added https.  Tried Stop / Start via the dashboard too.

The location pattern got me some logging.   Almost there I think. Working on a log error.

Still not getting this to work.  I can see the firewall is letting it through on the external port, but I see no activity in the http logs in nginx.  Here are my settings using just strait http (externally port 8888 for testing) to avoid any complication until I get it figured out.

Thanks @fabian.  I think I got the Let's Encrypt working fine.  The nginx is confusing as heck and I don't quite understand what I'm suppose to do.  I've created an upstream (whatever that is) and upstream server (whatever that is), a location (whatever that's for), an http server (this actually makes sense I think - the box I'm sending the traffic to).  I haven't even gotten into the ACL and WAF.  Sure wish it was as easy as a port redirect with a few options.  I'm trying to read through the site's instructions, but they seem to be missing some pieces and don't really explain what is being configured and how it's all supposed to work together.

You have https://wiki.opnsense.org/manual/reverse_proxy.html and I'm like, yes! I want to do #1 or just start with#2 and work toward #1, but it doesn't actually tell you how to do it.  So I've been trying to follow this load balancing doc, even though I'm not load balancing, but it's just not working.  https://wiki.opnsense.org/manual/how-tos/nginx.html

I'm needing some guidance on setting up a web server behind OPNSense.  Initially I just did a port forward, but I want TLS.  So I installed the Let's Encrypt Plugin on OPNSense, but I'm not sure how this works with port forwarding as the server itself needs the cert as it does the encryption exchange.  I don't want to open the web server to the world (I have a Alias defined IP ACL).  So just installing Certbot on the webserver is not an option unless it somehow interacts with OPNSense to allow the temporary proxy.  I also don't want to set up some method that copies the cert from OPNSense to the webserver as that would involve too many potential problems and security issues.

I'm also interested in putting a WAF in front of the web server, though this is not required.  So maybe some nginx method is possible, where the Let's Encrypt on OPNSense is served to the Nginx plugin which acts as a front end to my webserver?  Then the Let's Encrypt plugin has something called a HAProxy, so maybe that's the solution?  I'm finding documentation on these aspects of configuration very limited for my situation and I could really use the help trying to get this set up correctly.  Thank you for any help you can provide. 

As an additional note, I need to be able to access it both internally and externally.  DNS will resolve to the external IP, but I don't know if I need to do some reflection or anything since it would need to go out and then back in.

Was not able to get this to work for me.  Able to access it from the outside fine.  One difference for me is that I'm trying to do a port redirect.  443 on the outside to 8080 inside.  Tried with and without NAT reflection.  Event tried to create similar rules specifying the LAN source to WAN destination.  No luck
