how does one use a modpack in a server?

[raschwolf]

I made a custom modpack, and am looking to start a private server. however, after setting it up via hamachi, it was running really slowly. I did a lot of messing around, lowering rendering distance, that sort of stuff, but to little avail. it has now crossed my mind that perhaps there is something wrong with the way that I have my mods done. the modpack work almost perfectly on single-player (the only problem that I have is that the buildcraft icon is just a pink block. I have no idea why, Ill probably look into it. later.) and I have ran hamachi servers before using tekkit lite. do I need to use different mods when running it on a server? or perhaps I just need to use different jar/coremods (such as forge)? I'm guessing that this is a very stupid question, no matter what the answer is, but I seriously have no idea. thnx.

If you can, run the server and any clients on different computers. If you already are, you might need to take out some client-side-only mods running on the server.

I'm already running the server on a separate computer, but I hadn't thought of removing the client side mods. Thnx, I'll give it a try.

also, I found out what was up with buildcraft, the stone/iron/gold/diamond gears all had block ID mismatches that hadn't been previously detected.
