Why wont Terraria take my IP address?
I can't figure it out and me and my friend want to play in the same world...
You might be inputting the right IP address but with the wrong set of instructions. In the IP Address box, besides where you type the IP address is a box, input 100 and not 1 for it to accept the IP adress.

LogMeIn's Hamachi should easily allow multiplayer. It worked for me.
For me after I forwarded the port 7777 my friends could get on with my ip (to find it just search "what's my ip" in google) just make Shure your port is forwarded and your firewall is setup to allow java
