I am running two servers on my desktop pc. One is a normal minecraft server downloaded from minecraft.net. The second is a tekkit server. I have correctly port forwarded my tekkit server to 25564 in the server properties and on my router. My host computer can connect the through the ipv4. I got my multiplayer ip from "ip chicken" and it works for my non-tekkit server but i cannot connect to the tekkit server using my ip:25564. What am I doing wrong?
