 If you want SDL_mixer instead of FMOD, add -dUSE_MIXER.
+If you want the server to be able to forward ports via UPNP, add -dUSE_MINIUPNPC.
 To build a headless (no video/audio, for dedicated servers) executable, add -dHEADLESS.
 Replace -O3 with -g -gl to enable debugging features. Run the game with --gdb when using a debugger to
 prevent it from eating exceptions.

 Static Linking
@@ -35,8 +37,9 @@ It is now possible to link windoze LibJIT and ENet as static libs.
 
 First, you need to clone ( http://repo.or.cz/d2df-binlib.git ) (repo with prebuilt windoze libs).
 Then, you can use:
-  -dLIBJIT_WINDOZE_STATIC  -- static LibJIT
-  -dLIBENET_WINDOZE_STATIC -- static ENet
+  -dLIBJIT_WINDOZE_STATIC       -- static LibJIT
+  -dLIBENET_WINDOZE_STATIC      -- static ENet
+  -dLIBMINIUPNPC_WINDOZE_STATIC -- static MiniUPNPC
 
 Don't forget to specify lib*.a location with -Fi<...>
