Solving Problems
If you have LAN connection problems
"lan -g" shows the gateway address. Make sure it is the address of your
gateway if you are connecting from another subnet, 0.0.0.0 if you are
connecting from the local subnet.
"lan -p" shows the port is 6470. If the port is not 6470, you must change it
with the "lan -p 6470" command (unless you have deliberately set the port
number to a different value because of a conflict).
