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 < [ mailto:elder.co...@talklink.com.br | elder.co...@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 ?
