I just ran Shields Up and noticed port 21 (FTP) is wide open, while all the other ports marked as stealthed. The router is a Linksys WRT350N with the latest firmware 1.03.2. SPI Firewall is enabled and it's blocking "Anonymous Internet Request." This is alarming unless I'm missing something obvious. https://www.grc.com/x/ne.dll?bh0bkyd2 Anyone else with the same router and configuration please run the Shields Up port scan at GRC to see if your port 21 is open and report back. Thanks!
