As a newcomer in 2020, trying to sort out connecting to the multiplayer server list has been a little puzzling. I've done some experimenting and I finally ended up with this:

1. Grab this zip: http://www.freelancerserver.de/download/flgls_workaround_v10.zip
2. Extract the files. Copy gls_workaround.dll and libcurl.dll into your Freelancer\EXE directory.
3. Open dacom.ini in a text editor and add gls_workaround.dll to the bottom of the [Libraries] section.

That's it.

NOTE:
* The zip contains a dacom.ini that includes libcurl.dll in the [Libraries] section. This does not appear to be necessary.
* I'm not certain what the gls_workaround.ini file is for, but it also does not appear to be needed. Maybe someone can clarify this?

Observations:

1. After only updating the [ListServer] section in freelancer.ini to point at gun.fllistserver.com, I only saw about half of the available servers. After starting the game, I noticed if you only see global servers the INTERNET multiplayer selection and none in the LAN, then the global override DLL is not enabled.

2. As stated above, gls_workaround.dll needs to be added to the [Libraries] section in dacom.ini, BUT you also need libcurl.dll present along with gls_workaround.dll in your Freelancer\EXE as well (it's not installed with vanilla). I mention this because there are .zip packages out there with the gls_workaround.dll but not the libcurl.dll. Again, without libcurl.cll **THIS WILL SILENTLY FAIL**.

3. As of this date, Dec 05 2020, the old DLLs from 2007 still continue to work (supplied in the link I posted above). It does not seem like any other patched DLLs are needed.
