not logging some ports?
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

"Multiple Internet Connections" with four interfaces
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

access deny host (ip) to access the Internet
I''m using shorewall 2.0.x at home as an Internet gateway for family. However my brother always plays online games overnight, so my parents asked whether I can do something on the gateway to control the time of accessing the Internet. I planned to put a script on crontab to schedule which it will execute say at 12:00 night daily, the script will execute a command will deny my brother

Dropping established connections
Hello, I have searched the list but couldn''t find the right answer. I want to drop an established DNAT connection but could not manage it yet. Someone earlier said to bring down the public interfaces, stop shorewall, bring up the public interface and then start shorewall again but this won''t work. I also saw a message from Tom that someone then should unload all iptables

Restricting access by time of day in Shorewall?

I now have a situation where I need to enforce access restrictions on a specific computer during specific times of day -- e.g., a particular computer might have no Internet access at all between 10 PM and 6 AM. Is there any way to do such a

Packet Not 100% Received

It can received 100% requests. But when we put shorewall in front of it then it stats to loose requests. Is there any packet limitation from shorewall all it''s about conntrack? Thanks for the reply.

blocking
As i can see, if i use Shorewall tools for blocking client traffic ('blacklist' file, 'shorewall drop') it has effect only for new connections but existed don't blocks.

Shorewall config format
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

masq problem
Hi everybody. I''m sorry to bother you because I''m probably doing something wrong, but I have already read the documentation and I have been using shorewall for quite a long time. I recently installed 3.2.3 from source (but there was the same problem with 3.0.7 from apt-get ... -t unstable) The thing is, that I can''t get masq working. Maybe this is because
