Something is accessing the FTP server from my machine . . .

. . . and causing the firewall to activate. Typically it uses the current IP and attempts to gain access to the server every 30 seconds for twenty minutes using an old username. This happens several times a day. I am tired of resetting the firewall and the ISP cannot help. Any help would be appreciated. I am using WHM.

Thanks,

Martin
