Modded server doesn't recognize that mods are installed.

I've put together a custom modpack, and tested it on singleplayer to make sure it works (which it does) but when I load the forge universal and mods folder onto the server, it won't recognize that mods are there. I can get modded items from creative tabs, but the weapons and tools don't do any more damage than normal, and any modded blocks I put down are instantly removed. Does anyone know what's going on?

I downloaded the latest installer.jar from the minecraft forge website, and installed the server version into a folder before adding the mods folder and the config folder. To launch the server, I double-click the forge universal that appears after I install it.
