Why is it that the NSPs I've encountered refuse to do any sort of sanity filtering on their customer connections? i.e. If UUNet knows that FDT has only 205.229.48/20 and 208.215.0/20, why should they let me send traffic through their network with random source addresses? FDT has been the target of forged source address UDP attacks for the past 2 days. It's all being stopped at our router that takes our UUNet T1, but the extra T1 traffic is causing UUNet's usually unreliable network to be even less reliable, and we've lost connectivity to UUNet several times this evening. 5 minute input rate 1326000 bits/sec, 318 packets/sec 5 minute output rate 469000 bits/sec, 286 packets/sec PUNet suppost says there's nothing they can do, and that I should talk to their security people about buying a firewall for FDT on monday...like a firewall on our side of the T1 is going to do us a lot of good.... ------------------------------------------------------------------ Jon Lewis <[email protected]> | Unsolicited commercial e-mail will Network Administrator | be proof-read for $199/message.
