hi list, this is my first posting in the list here. At the moment I am reading the Advanced Traffic..... How-To. perhaps some one can tell me how to realize my idea. We have a data-server which is used by different subnets in our company. now I want wo put a linux-box in front the dataserver which control traffic usage to the different subnet´s. is it possible to do this transparent and dynamic? linux bridge? UserPC | | Subnet1 ---- Router ------100Mbit--- | switch <-100MBit --> Linux-Box <--- 100MBit ----> Dataserver | Subnet2 ----------- 100MBit------------ | | UserPC Subnet 2 should have 80% of capacity. Subnet 1 the leftover. and perhaps it is possible to to speed up Subnet1 when the reserved 80% for subnet 2 are not fully stretched. Thank you. greetings Benny -- Mit freundlichen Grüßen / Best regards THALES COMMUNICATIONS GmbH Benjamin Albrecht Dept.: DP/CIT Tel.: +49-7231-15-3962 Fax.: +49-7231-15-3813 eMail: Benjamin.Albrecht@de.thalesgroup.com
