tommy.eriksson () ctakt com I'm looking to do a setup like this: Net | Router | Snort Box (Doing Ethernet Bridging) | Switch /\ / \ / \ smb billing etc <-Private || Public Net-> www ftp mail dnsMy question is, could the snort box doing ethernet bridging actually block tcp/udp/icmp/etc/etc type packets coming over the network with this approach (freebsd or linux) even though it is transparent to the network (I might assign an IP for remote access).
Thank you very much for your time, sponix

One problem takes me a lot of time. In our company we want to improve our security. We have comercial firewall. We choose snort as IDS solution. Snort runs on Linux machine infront of whole network. Whole IP traffic passes through it. Now, we want to configure ipchains with snort.I found guardian script that automatically do that. It works ok, but we haveproblem with ipcahins. When attack came on IP address of Linux machine IPchains blocked it correctly. (Linux machine has only one interface.) Problem is when attack came on IP addresses of comercial firewall (which is behind snort), nothing happend. It seems that ipchains blocks only traffic for linux server. I failed manually to block other ip addresses. How can we block whole range of ip addresses? Thanks for any help, Drazen _______________________________________________ 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
