hi elder, 

depends on what you want. normally the smallest allowed prefixes on the 
internet are /24. you should always try to be as specific as possible in order 
to avoid strange behavior. 

I think you only have 1 prefix to reject do then its better build a reject 
filter as a permit filter would be too hard to maintain 

Kind regards 
kurt

Thanks Kurt ! 
This what i needed ! 
Plus one question... 
What would be the best practice in building this filter ? 
Would have with build for reject when gateway is a specific, our just by net ?
