When I run the server.bat, it opens, and log shows:

Server started
Loaded map "kids3.alm"
Connecting to hat...
Connection to hat failed.

My LAN IP is 192.168.1.3, my internet IP is 71.102.190.49.
In the server1.cfg, it shows:
HatAddress=192.168.1.3 ; hat's address
IPAddress=192.168.1.3:8001 ; "Server" address and port for clients
; if you use default port, the second
; IP address is not required
IPAddress2=192.168.1.3:8002 ; Connect to hat from this address and port

But I don't know exactly what it wants for an IP. I've tried both my LAN IP and my internet IP. Any help would be appreciated.

forward ports 8000, 8001 to 192.168.1.3,
add alias 71.102.190.49 to your machine (if you are running Windows with DHCP, you can't do it)
and set IPAddress=71.102.190.49
