Please help secure port 12345 on router.Forum: Networking Topic: Please help secure port 12345 on router. started by: khurdp Posted by khurdp on Jan. 01 2006,21:49
Greetings folks,My network setup - SBC Yahoo DSL modem -> Netgear MR814 router. One Fedora Core 2, a WinXP and a DSL connected to the router. The router has no port forwarding at all. Now if I visit < http://scan.checkit.com/trojan.aspx > from either the linux or XP machine, checkit reports(for both) my port 12345 Closed which means my router is not listening but rejecting requests. Rejecting a request alerts hackers to the existence of a computer at the ip addr.. Now if I connect my linux machine to the modem directly, all my ports are reported 'Blocked' which leads me to believe my linux machine firewall as expected blocks the port 12345 and it is my router that has something wrong. I logged into the router to confirm there is no port forwarding, if so what exactly is happening here. Is the 'checkit' report correct or do they just want me to buy their software firewall? Also please suggest how i can secure the 12345 port ON the MR814 router. Thank you, regards Prasad Posted by khurdp on Jan. 03 2006,14:20
Well, I installed the latest firmware and copied (manually) over the settings. I had backed up the settings and could have read them in but I reentered them so as to eliminate any chances of repeating an erroneous setting. Now checkit.com, grc and others all show the 12345 port 'Blocked'. regards, Prasad Posted by doobit on Jan. 03 2006,14:35
