Hello, I want not to log some dropped packets going from net to fw, i.e. to exclude some ports. For example, I get lots of denied SPT=4672 DPT=7476 packets in /var/log/messages. I know I can probably do this by using ulog or some other logging system and writing some rules to exclude "SPT=4672", but is it possible for shorewall not to log some ports? Sorry if it is obvious, but I

Hi, I''ve been working the past 8 hrs combatting DDoS attacks on websites and dedicated servers I host for clients. They''re hitting one specific IP address, but coming from thousands of external IP addresses. I use: shorewall-4.0.10-3.noarch How can I tackle this? I''ve blocked many subnets in the blacklist file but it''s made very little difference. If

Hi, I''m a long time shorewall user and I like it very much. There is only one thing were I''m not always happy with: the config files. There has been discussion on the list about the comments in the files. My concern is that I loose overview over my configuration because of the many config files. Of course there are advantages too but I thinking wether another config format would

Hello list members, Over the past 12 hours my firewall box has had over 300 hits to port 1434 from numerous ip''s. I ran tcpdump on a couple of them and it looks like the ms-sql exploit attempt. I don''t use ms-sql. I''ve always gotten a few hits per day, but now it''s gotten out of control. I use logcheck to email the system logs to me and at this rate by the

Hi, I was reading document http://shorewall.net/MultiISP.html#idp3634200. Inspired by the document I was trying to establish the following changes: * one additional interface: COMA_IF * COM[A,B,C]_IF interfaces request IP address via DHCP * all non-RFC 1918 destined trafic is NATed from INT_IF to COMA_IF * all non-RFC 1918 destined trafic from GW is routed via COMB_IF by default * non-RFC 1918

I have what strikes me as an odd problem with shorewall. Let me describe my setup. My desktop (alfred) is connected to the network through an ADSL modem. I am running rp-pppoe, and this works perfectly. I have a small home network, with two LANs; an Ethernet LAN (including a machine running Windows XP), and a WiFi LAN, including the laptop (william) I am using now. All the computers except for
