I am having a problem with connections from a server behind a shorewall firewall. Both machines are running redhat 8.0 with a custom 2.4.20 kernel. The problem lies with a mail server I am configuring which has been able to send mail to all hosts, except this one. The connection starts with the SYN_SENT, and then just hangs there. (telnet to remote server on port 25 just hangs trying to

Hi Tom and other gurus, I modified SHOREWALL (version 2.0.15) for bridging and I cannot restart it. I got the following error ... Processing /etc/shorewall/policy...

I''m using shorewall with openvpn and traffic shaping at all of our offices. I have noticed for a while that occasionally ping times are excessive. Usually this is during overnight off site backups but some times during the day. I have assumed the is was an ISP issue but now I''m suspecting it''s problem with openvpn and traffic shaping. In the test case have 2 sites

Hi, I''ve upgraded my shorewall version from 2.0 to 2.2.1 using the .tgz I followed the instructions for upgrade and got a warning when running shorewall check on /usr/share/shorewall/action.DROP and action.Reject using "dropNonSyn" while that has changed to DropNotSyn . I manually copied over action.DROP from the source tree. Question: Are there more files to check ? Even

As 2.2.0 is nearing release, I''ve begun to think about what I''ll do for 2.3 and I think that it is time for Shorewall to add support for IPV6. Because of parsing ambiguities, the need to maintain upward compatibility with both Shorewall and 6Wall, and different available functionality in IPV4 and IPV6 Netfilter, I believe that it is going to be necessary for some files to be

Hi, I am new to VPN an OpenVPN with shorewal. I tryed a lot and read a bounch of howto''s but nothing helped so I came here. I want to tunnel all request to my server 141.48.XXX.XXX from my home network throu port 443. I want to do this because this is the only way I can connect to my server using ssh or ony other tool or port. On Port 80 Apache is running, so I only have the https port

Hey all- Trying to run sh 1.2.8 and iptables 1.2.5 on my linux 2.4.17 box. I build the kernel from kernel.org sources, and then patched it with iptables 1.2.5 by doing %make pending-patches KERNEL_DIR=/usr/src/linux I let it run and patched these: Welcome to Rusty''s Patch-o-matic! Each patch is a new feature: many have minimal impact, some do not. Almost every one has bugs, so I

Everyone, Progress was slow today. I started out well, but then I ran into Documentation.htm. Progress slowed considerably, as I analyzed the document structure. I''m up to /etc/shorewall/hosts Configuration. I hope to finish Documentation.xml by tomorrow evening. Converted documents: 6to4.xml CorpNetwork.xml FAQ.xml Please post feedback, if you see any problems with the converted

Sorry for asking this, as I believe it to be a kernel-related rather than Shorewall-related problem. But some of you guys seem to have a lot of experience with these kind of things. I''m setting up a NAT''ing router with two ISP lines. At first sight, everything works as expected, however when the local machines try to keep a TCP-connection open for a long time, it disconnects

Hi Tom, I nearly completed the test and installation related to http://www.shorewall.net/PPTP.htm. However, there is no serious problem when it is operated as it is in the general companies, but there is Client Program for MS-Window that is operated only by Public IP. So I am very concerned about it. I would like to use Internet through Gateway in (B) as local computers in (A) receive Public

Hi everyone! First of all, sorry about my bad English and the e-mails extension. I need some help to implement a VPN connection using shorewall and openswan as IPSec Tunnel. My network map: CLIENT VPN APPLIANCE --> +++INTERNET+++ --> FIREWALL --> OPENSWAN SERVER (DMZ) I have two VPN connections with two different subnets to the other end. The two of then are correctly established.

Hi guys, I''m trying to setup an IPIP tunnel between a Cisco router and a firewall running Debian GNU/Linux Sarge with Shorewall 2.0.13. I''ve read and implemented the http://shorewall.net/IPIP.htm document, but I don''t understand why there should be at the same time a "tunnel" and a "tunnels" script. Shorewall still refuses to let the

Hi all, I''m using Gentoo Linux Distribution and I''ve upgraded my firewall from Shorewall 1.4 to 2.0.4, however my LANs stop having internet access. I have a server with shorewall 2.0.4 installed and 3 interfaces. eth0 and eth1 are interfaces to a LAN and to my laptop and eth2 is the net interface. I have masq like: eth2 eth0 eth2 eth1

Hi all, I have set up a working OpenVPN2 connection between my Server and my gateway at home. Now I want all traffic to be routed through this VPN connection. Currently everything is going through eth1 to the internet (to the gateway of the University which forwards it to the internet :-). We must use a prox-server and because of this I am not abel to watch the real-Media streams on

I am not sure how to accomplish the following example: Local 10.1.10.0/24 <port 14143> to a specific server on the Internet <port 24243> I have seen this called a tcp proxy bridge? I have it running on a NT based proxy but wish to move away from NT. I am running a two-interface firewall with a squid manual proxy for http. All works well except for this requirement. Setup is as

Hello, I''m not a subscribed user to the mailinglist and I try to install shorewall and get following error when I try to start it: iptables v1.2.11: invalid TCP port/service `ssh'' specified Could anybody tell me my mistake? Best Greetings! -- Fabian Braennstroem
