I have searched your FAQ''s and read the documentation on your site as well as googling. I am not able to figure this out. If you have any ideas can you please help. I am using the linux-ha failover with redundant firewalls. As part of the function of the linux-ha software consists a service called heartbeat which is a connection from each failover node through a serial cable or ethernet.

Hello shorewall-users, we have a strange problem where some of our customers cannot access our webshop, but most of the customers can. I have been slowly eliminating possibilities and am now left with either the firewall (Shorewall 1.4) or the webshop server. What appears a lot in the logfiles is: Jul 26 11:51:04 gw kernel: Shorewall:logdrop:DROP:IN=eth0 OUT=eth1 SRC=84.128.198.240

Is anyone using Shorewall and DNATing their ssl connections? I have replicated my port 80 configuration for 443, but cannot connect through the firewall (page cannot be displayed). SSL is working behind the firewall. Am I going about this the wrong way?

Hello, On my systems i use shorewall 3.2.6. Now all systems where replace by new ones with new ip''s. So i tried with DNAT to map the old ip''s to the new one as long as DNS is updated. But i didn''t get it work. I see in tcpdump that a connect from client-ip to new-server-ip is done while connection the old on. But i get no response. Did i configure something in the

Hello all: I''ve got a confusing issue. I had a working shorewall configuration (based on the two interface model) using DNAT for redirection to my HTTP server. The HTTP server is on my inside network (I know - bad juju, but one thing at a time). I changed my configuration this morning to use views in my BIND (named) configuration. Everyone outside the firewall is able to get in

I''ve had some issues with my network, and I''ve had to reconfigure my Gibraltar CD. It runs shorewall 1.4.8, and I have a 2-interface setup, so I downloaded the relevant files from the install page. Masq and such works, but I''m having a problem with my port forwarding. It works for port 22, but it doesn''t seem to work for any other port. I''ve turned

Hello all, Yesterday I noticed that my system was "leaking" traffic towards the 10/8 network, I have shorewall installed on multiple machines ranging from single interface devices to ones with 10+ interfaces. I tested all the boxes and they are showing the same behavior. All systems are CentOS 3.4, 2.4.21-27.0.2.ELsmp. Shorewall version: 2.2.1 For the host mentioned is a single

Hello: I just started using Shorewall this morning and must say that I''m very impressed. Much nicer than what I was using previously. I love the ability to type ''shorewall logdrop ww.xx.yy.zz'' and completely block a particular IP address. However, the log part doesn''t happen. When I look in the logdrop chain, there is no LOG prefix. I''ve looked
