You're welcome :) AFAIK there's nothing really OPNsense specific when it comes to packaging, other than the fact that they cloned the upstream ports tree and added some internal packages.

That's probably also why there isn't really any OPNsense specific docs for this. The FreeBSD Porter's Handbook covers this stuff in quite a lot of detail and I'd generally recommend it over any other guide, although it's fair to say it's not exactly the most beginner friendly read.

It depends on what you want to compile and how you want to install it.

Ideally, you would use a FreeBSD VM with the ports tree to compile and package the software. Then you can simply copy the package over and install it with pkg.

If you just want to compile something random, e.g. a Go program or something similar, and don't want/need to install it as a package, you can usually compile it on your existing system with the target OS set to FreeBSD and then just copy the binary over.

One feature I would find helpful is the inclusion of the rule descriptions, ideally in the main view or at least in the details view and also when '-j' option is used.

I've looked into it and it'd be nice, but the filter log doesn't contain the description. The only thing I can think of is to use the rule id from the log to somehow find the description somewhere else.

/conf/config.xml has descriptions of rules you've added manually, but default rules aren't there. The rules in there are also referenced by a uuid, not by the rule id from the log. I don't know of any other place that has the rule id and the description (of all rules).

If anyone knows a better way to do this, I'd be open to adding this.

It would be helpful if it could read multiple file or a directory...

@patient0 I forgot to mention I've added this in v0.10.0. You can now open multiple files or pipe data via stdin, and it all shows up in one view like it's a single log.

The input has to be a file, so if you want to load a whole dir, use globbing. Everything gets sorted so it doesn't matter what order you pass the files in, the logs are always displayed in chronological order. If you have >40-50gb of logs in the dir, it... takes a while to index, but it works pretty good/fast after that.

i guess dhcp was just kind of slow?

you later got an ip, /usr/local/etc/rc.newwanip ran and configured everything

For anyone interested, opnsense-filterlog is now also available as a binary package (thanks @franco!) and can be installed via pkg:

Code Select Expand

pkg install opnsense-filterlog
The package comes with a man page that's got pretty much the same info as the README:

Code Select Expand

man opnsense-filterlog
Currently v0.8.0 is in the repo, v0.9.0 will come with the 26.1.6 release and can now parse all filter log fields/protocols, filter by time, etc.

Kommt wahrscheinlich drauf an, wie komplex das Setup ist. Mir ist bisher nur aufgefallen, dass Captive Portal Sessions nicht gesynct werden. Beim Failover fliegt die Verbindung raus und man muss sich neu einloggen, damit der Traffic wieder durchkommt.

Welchen DNS Server verwendet der Client? Was steht in der Client Config unter AllowedIPs? Poste einfach mal die Config als Screenshot.

Mullvad support also told me that they wouldn't support psk-exchange anymore.

Makes sense. I haven't tried it myself, but it seems like it could be (ab)used to get around the five-device limit, since you get both a PSK and a primary key that isn't visible in the account settings.

Laut src/if_wg.c ist die Zahl nur eine interne ID. Irgendwie komisch, dass sie fürs Logging verwendet wird, sich aber nicht mit einer IP/einem Pubkey verknüpfen lässt. Wahrscheinlich bringt sie den Entwicklern was, für End User ist sie anscheind nicht gedacht.

In case you aren't aware: psk-exchange can be used to obtain a PSK that you can simply put in the WG config, like you would with a "normal" WG server, no mullvad-upgrade-tunnel needed. You need to compile it yourself though, since this isn't really officially supported, but it works.

@allddd

I think you could create a PR here that adds it to the opnsense sub directory:

https://github.com/opnsense/ports/tree/master/opnsense

If you need inspiration check out recently added ports there (eg ndp-proxy-go or hostwatch)

https://github.com/opnsense/ports/pull/252

I hope I've gotten everything right, it builds and installs without issue in a clean FreeBSD VM.

Hi allddd,

Nice work on this!  If you want we can work on including this in a future release as an optional binary package and see how it goes from there?

Cheers,
Franco

Hi Franco,

Thanks! I'd be honored, just let me know how I can help :) Would you need any changes to the Makefile/build process, maybe an install target? A man page would also be nice.

Is this a likely event for, say, 26.1?

The project itself is "ready", I've added both the manpage and Makefile targets a few versions ago. I don't know when it will happen though, @franco might be able to say more.

Did you experiment with the ports being in color and/or the direction being bold or in color?

The styling library I use supports adaptive styles, so you can define separate color schemes for light and dark backgrounds (even using different colors for 256-color and truecolor terminals). I wasted so much time trying to find the perfect color scheme, only to find out that half the terminals report the wrong background color... After that, I tried using just bold and faint styles, but even faint doesn't work on light backgrounds...

I've now added colors to ports and IPs in v0.7.0, which should hopefully make it more readable. No fancy adaptive styles though, I'm just using 2 colors that should work on both light and dark backgrounds (and don't look that bad on dark).

I also changed the direction indicators to I/O (with space), and it's indeed much more readable. Thanks for the suggestion!

Thanks for checking it out :)

And the view is a lot more compact, I do like >/< as indicator for incoming or outgoing traffic. It does make it a bit harder to read, I'd prefer to have the direction in it's own column or maybe a space between it and the interface (or O/I, not sure)?

I don't think a separate column is necessary, since the direction always appears before the interface name and it's therefore just as easy to spot as it would be in a separate column. I'll try adding a space or using another char to see if it improves readability.

And I can scroll to the right for infinity, maybe it would make sense to not go over the right end? Jumping to the beginning and end of a line is removed, I assume because it's hardly necessary since the view is already very compact?

Jumping to the beginning/end would require checking the view length on every render, and with such a compact view it's just not worth it. Preventing scrolling past the right edge has the same issue. I looked at how less handles it to get an idea, and even there you can scroll infinitely, so in my opinion it's fine to do the same here, especially now that horizontal scrolling is rarely needed.

The scenario when filtering for protocols with ports I think the view is not easy to read in regards to spotting the source port, with IPv4 and IPv6 address.
If filtering for one or the other it's a lot better.
Though I still think it could help to place the '>' in 'Source > Destination' at the same position for all columns.

Yes, as plain text that view isn't very easy to read. Does your terminal support formatting/colors? I haven't updated the screenshot in the repo yet since the view may still change a bit, but I've added formatting that makes it easy to see the difference between IPs and ports:

If I make the ">" line up at the same position for all lines, we basically end up with the old view again.
