hey i just started a dedi server and every time i got to connect to it thru game it says YOU MUST ENTER A VALID LOCAL NETWORK IP ADDRESS
does any 1 know why it's saying this and i have the correct information inputed

You haven't entered a valid ip addrdess?

I've done this before but I can't recall exactly how I do it... try the following:

if ded server is on your machine, connect to "127.0.0.1" (or "localhost" will work too I think), no quotes.

OR connect to the local ip of the server not external (eg 192.168.?.?)*

* to find out the ip in windows (of the server computer) go to start->run and type cmd
then in the dos window type ipconfig and it should tell you what your local ip is.

Pretty sure the first one will work anyway.

oh and I'd avoid using swearing acronyms in your thread title if you like not being banned

Quote from the_angry_angel :

LFS only accepts LAN IPs in the RFC1918 range:

1. 10.0.0.0 - 10.255.255.255 (10/8)
   
2. 172.16.0.0 - 172.31.255.255 (172.16/12)
   
3. 192.168.0.0 - 192.168.255.255 (192.168/16)

Any other range is an invalid LAN IP address and you should ideally be using the master server (this is by design to prevent crackers, etc).

If you like a server to play online with others, you must set usermaster=yes and ip=auto.
