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 ?
