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 Op do 21 feb. 2019 17:31 schreef Elder Costa <elder.costa@talklink.com.br:
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 ?
