....org/index.htm I have just discovered this great project. It seems it surpasses standard netfilter in performance. The documentation states they are more or less compatible with standard netfilter, but anybody has tested if it is compatible with shorewall? Tom, have you?

...s testing of firewall configurations/hardware. We have discovered hping that seems a great tool for this, but funny enough Shorewall cuts it !!! even when you leave ports open :) So besides hping, any tool for this? Why is shorewall cutting this traffic? Thanks in advance. Regards. -- Jaime Nebrera - jnebrera@eneotecnologia.com Consultor TI - ENEO Tecnologia SL Telf.- 95 455 40 62 - 619 04 55 18

...s means that state checking is done after all the rules involving from this zone to this zone. As you could have a lot of them, wont be better to place them just after checking the state is not invalid? This will mean a lot of packages will be accepted or rejected much faster.

Hi all, I have found problems in p2p traffic detection. The ipp2p module works fine but in shorewall the rules written for this protocols never match because the initials p2p connection (login) match in ''-m state --state RELATED,ESTABLISHED -j ACCEPT'' rule before ''-m ipp2p --ipp2p -j DROP'' rule, so netfilter never filter p2p traffic. I have had to run

...ing about iptables performance and know it reachs a limit around 500 rules and then starts degradating, but also know shorewall makes a great job dividing the rules in such a way the traffic doesnt need to pass all of them. Any clue? Any advice. We will be VERY appreciated. Regards -- Jaime Nebrera - jnebrera@eneotecnologia.com Consultor TI - ENEO Tecnologia SL Telf.- 95 455 40 62 - 619 04 55 18

Hi all, Anybody has configured a Shorewall firewall to protect Citrix servers? Could you give us some clue on the rules you have to define? Citrix opens a connection from the inside to the outside from a different port (more or less like ftp) and seems not works.

...d in netfilter? How? Any ideas? Does it work with kernel 2.4? And of course, can it be managed with shorewall? :))) Bear in mind I''m not talking about ISP redundancy but the firewall itself, if possible set as an active/active failover solution. Thanks in advance. Regards. -- Jaime Nebrera - jnebrera@eneotecnologia.com Consultor TI - ENEO Tecnologia SL Telf.- 95 455 40 62 - 619 04 55 18

...ters but doesnt need to pass trough the firewall, will dropping it on eth0 solve the problem? (That way there is no way the packets enter into other ethernet ports) What would happen with other multicast based apps? Would they need to be dropped too? Very thankful in advance.

I made an atempt to run snort_inline and shorewall on the same system but I could not get snort to see the packets. Maybe someone with a little more iptables knowledge could tell me what I''m doing wrong or if its possible to have the systems setup so that it places packets that the firewall would allow into QUEUE. After setting up and starting shorewall I then issue the following

Hi Tom and folks, There are some svn or cvs system for the shorewall-dev community?. If Tom want to leave the project for a while, maybe it will be necesary some cooperation system.

Is anyone using an inline IDS like hogwash or snort-inline to drop packets in a system running shoreline? I _think_ I see how to configure it, but I''d be really interested in finding a howto or something... Thanks! Mike- -- Mornings: Evolution in action.

I believe that 2.4.0 is about ready to be sent out the door. I''ve made a couple of small changes since RC2 but I don''t believe that they warrant another RC. There remains the issue of what to do about support for Shorewall 2.0 given that 2.2 has only been available since March. It would be my recommendation to make 2.4 the new "stable" release but continue to

Hello I am looking for a way to have snort to dynamically update my shorewall config. I have seen software out there but I would like to see if anyone had tried this first. Aslo I would like to know if there is a way clear the Netfilter tables when I do a shorewall restart. The reason being is that when I make a change to my firewall setting I want all connections to have to re-establish

Hi I''m currently setting up a game server and have opened all ports needed to run it. What other options do I have regarding protecting the open ports? I''m worried about people attacking the open ports to render the server useless. Any help or advice would be appreciated. Thank you. Recoil UK
