Hi, We have been moving some servers around here and one of the services that got moved to a new machine (and a new subnet) is our Retrospect backup software. One of the immediate problems I found was that I could no longer see the majority of my clients from the server. [Actually this problem existed before but since the server was originally on the subnet that most of the clients were, it wasn't hard to enter the remaining clients by address - however with DHCP and the addition of remote sites, this becomes unmanageable]. I have 7 class C subnets that I wish to search for clients in. The LAN is a switched network with mostly Cisco Catalyst 2924s. We have a Cisco 8540 layer 3 switch in place as well. The problem is that, for good reason, we have the layer 3 switch to not forward directed broadcasts to prevent smurf attacks - and thats exactly one of the mechanisms Retrospect uses to discover clients - a directed broadcast to the subnet. We tried to get the multicast stuff working via some configuration changes on the layer 3 switch but thats going to take some more research. So I'm wondering if anyone has Retrospect working in a multiple subnet environment with Cisco equipment AND with some reasonable security precautions in place (like "no ip directed-broadcast"). Better yet, anyone have it working with multicast, as this would be a preferred way to do this I think. For reference, clients are mostly Macs running 4.3 over TCP/IP, the server is also a Mac running 4.3. Thanks, Kevin -- Kevin M.
