The "Traverse NAT Status" is yellow?Is something wrong with my network or configuration?

There are many reasons to cause the status become yellow:
1)Both you and your peer has an un-traversable NAT devices.Don't worry about it , because VPN-X server will transfer/relay the network data for you and your peer.
2)The peers forbid you access his/her computer.
3)You and your peers should use UDP to connect VPN-X server for traversing NAT purpose, or the status will be always yellow.
4)Wait two minutes,then check the status.Maybe it will be green.

In most of case, you need not worry about the yellow status color.
