Why would/how could my ISP's router know anything about my internal network (dest IP = 192.168.1.20) behind a firewall doing NAT/masquerade? ----- Original Message ----- From: "Alberto Gonzalez" <ag-snort () cerebro violating us> To: "Ian Hunter" <ihunter () ix netcom com> Cc: <snort-users () lists sourceforge net> Sent: Friday, October 18, 2002 6:10 PM Subject: Re: [Snort-users] Newbie "what does this mean" question
first, IMHO you should upgrade your snort distribution. (eg 1.9.0 http://www.snort.org/dl/snort-1.9.0.tar.gz) actually its pretty sel explanatory what this is, ICMP _destination unreachable_. Alot of things could cause this. I usally get these messages from my ISP's router. Ian Hunter wrote:I'm running snort-1.8.4-3 on SuSE 8.0, and I'm getting TONS of messages
that
look like: Oct 18 14:38:19 lucy snort: [1:485:2] ICMP Destination Unreachable (Communication Administratively Prohibited) [Classification: Misc
activity]
[Priority: 3]: {ICMP} 130.59.33.17 -> 192.168.1.20 The FAQ says ignore it unless there are lots, and if there are lots,
figure
out where they're coming from. ??? What causes this? Thanks!-- The secret to success is to start from scratch and keep on scratching. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
