[smartBridges] HELP net traffic and where is it coming from

[Blazen Wireless]

I have Brilan bandwidth control and for kicks I put my servers behind it and just yesterday I noticed that I have a steady 250kbps up and down on my DNS and my mail server I unplug the Lan connection to my T-1 and the problem goes away so I know it is not my wireless customers? I did a sweep and found nor worms on my 2000 machine I do have Linux 6.4 machine that I don't know root so cant run any kind of scan but it appears that it is coming from the WWW? how can I tell what IP or where this is coming from its almost like a DNS??? things are functioning normal but a little slow since this is taking some of the bandwidth?? can or would my ISP (megapath) be able to tell where it is coming from???   I have a strange feeling the WAR has started between me and the competition since they threatened to do something for their 3 customers jumping ship and coming to me because of their poor service!   I have TCP IP Dump but cant really see any thing specific to those IP addresses??   Martin & Steve Blazen Wireless www.blazenwireless.com
