Hi, Just to let anyone using 3Com/USR gear with "HiPer ARC" term servers know that the latest release supports a new feature that will validate outgoing packets for the proper IP address. Release 4.1.59-1 includes a feature called "SAA" or "Source Address Assurance". It's basically an auto filter that will only let users source packets from the address they are assigned when they dial in. It can be globally applied or triggered per-user via Radius. This is a free download, no service contract required...
