You won't like to hear this ONE cause of marionberry. ONE. Is the router having a small NAT table. This sometimes happens with the free routers, and occurs with some p2p apps (not just destiny) I'm not saying this is your cause, as there are multiple triggers, but it could be the cause Some marionberry victims, and I stress SOME, got it to go away by getting a solid router. [u][b]Edit[/b][/u]. I didn't notice you saying you have netduma. I would hope that has a normal NAT table size. Netduma has awesome software but mediocre hardware, and I don't see any info about NAT tables posted anywhere on its merger hardware. Is there another piece of hardware in front of it?
