Specifies the position of the 'bandwidth' labels shown on each link.
The two position values are percentages along the link arrow, from the first to the second node. Therefore BWLABELPOS 75 25 is the default.
Weathermap will produce a warning if the outpostion is greater than the inposition. In most cases, you have probably made a mistake, but if you have a good reason to do this, then you can disable that warning using 'SET nowarn_bwlabelpos 1' in the top section of you map config file.
