Tcp/udp

Is there anybody that can help me with this comment I have received as a result of a query I sent, in regards to Live for Speed an on line racing simulator, its double dutch to me being a silver surfer. Thanks in advance if you are able to help

""Please first try this : On that listing screen, at the bottom you see the
button with TCP in it. Click that in order to enable it. Then refresh the
list of hosts and see if some hosts will appear.
If they do, then in all likelyhood your problem is due to your router not
passing through UDP packets.

In networking there are two main types of network packets, called TCP and
UDP. TCP is a very reliable one, but relatively slow. UDP is a fast one, but
not 100% reliable. For the list of hosts LFS uses the UDP kind, because with
TCP it used to take ages before the list would be loaded. UDP is still
reliable enough that it will be able to connect to 99.9% of all hosts at all
times.

However, for some reason routers sometimes have problems with udp packets.
It could be as simple as a router reboot to fix this, or otherwise you may
have to go into the admin panel of the router in order to check its
settings, or maybe revert to default.
But the variety in routers is so large that I'm afraid I cannot really help
with that more in depth.""

It's suggesting that within the game server lists you click TCP or UDP and see if the game lists servers you can connect to. If not and you are behind a router then you'll need to set-up port forwarding.. The way to do so is dependant on what ports the game needs and also which router you have.

For LFS the port is 63392, check your router manual as to how you set that up for both TCP and UDP
