I have hosted a server from my network and it works perfect on the computer I'm hosting from and computers outside the network. But other PCs inside the network(in the LAN) can't connect so well. I have forwarded all necessary ports and people outside the network can connect. The people inside the network gets stuck at each log (handshaking, authenticating, connecting and all that) for like 5 Min each and when they finally can connect it lags like hell and its over 5000ms. For the hosting comp and computers outside it runs smoothly as silk.
Help?
