 You can also selectively enable/disable other features (e.g., specific plugins you don't care about, or whether or not you want to build the recordings post-processor). Use the --help option when configuring for more info.
 
+### Building on FreeBSD
+* *Note*: rtp_forward of streams only works streaming to IPv6,
+because of #2051 and thus the feature is not supported on FreeBSD at the moment.
+
+When building on FreeBSD you can install the depencencies from ports or packages, here only pkg method is used. You also need to use `gmake` instead of `make`,
+since it is a GNU makefile. `./configure` can be run without arguments since the default prefix is `/usr/local` which is your default `LOCALBASE`.
+Note that the `configure.ac` is coded to use openssl in base. If you wish to use openssl from ports or any other ssl you must change `configure.ac` accordingly.

 ### Building on MacOS
 While most of the above instructions will work when compiling Janus on MacOS as well, there are a few aspects to highlight when doing that.
