Hi I have a atrange problem and don''t know where to look anymore. I have 4 interfaces running on RHE3 on a Dell XEON server 2.8Ghz 1Gb RAM. The primary use (only one at this stage) is for the server to handle mac address authentication of clients which it does. The problem however has to do with througput. I have 3 DMZ''s which one is a private range doing masquarading and

I noticed the long standing Ipsec FSwan problem was fixed. But do you still have to make sure Ipec is not running when shorewall starts Reason I ask Is I could not get my Dmz working with Ipsec in the equation. Thanks Mike

I have had a web server listining sql-1433, www 80, ftp-21 using proxy arp with sub-netting in a three interface DMZ. All these ports are in the rules file as ACCEPT. With one exeception that 1433 allows a few host from the net. 21 and 80 allow all net to dmz connections. The policy is DMZ to net ACCEPT This has been working great for about a month or more until I rebooted the

I''m very new to shorewall. My setup is IP Gateway (CentOS 4 + Shorewall) with 3 NIC cards. Shorewall works great on the firewall machine. Bind also works (local net machines get IPs fine). Under firestarter, all works great. With shorewall, the loc machines can not route past the firewall. They can connect to the firewall, but not past it. Exactly what information should I post to get

Hello Tom, I have successfully configured proxy arp subnettinng on my network with three hosts in a Dmz. And it works great. (using proxyarp in interfaces) I also tryed this on network below same trouble. However for this network below I have tryed to configure one host in a Dmz (using /etc/shorewall/proxyarp) which works and comes up after I set it up and clear Isp''s arp

In an effert move my Dmz from a snapqear roouter to Linux with shorewall. Question is I have network 64.42.53.200/29 which makes default gw 64.42.53.201 network 64.42.53.200 broadcast 64.42.53.207 mask 255.255.255.248 and I want to set up shorewall with eth0 64.42.53.202 eth1 local eth2 dmz where dmz will use say 64.42.53.203 for web and email server. Where I do not need or should I say use

Hi, I have been a shorewall user for a long time now, and it has been working flawlessly. I have now changed ISP and my new DSL connection is PPPoE.

Hi folks, Has anyone tested the changes to multiple ISPs/load balancing or routestopped in 2.4.0-RC1 yet? We need to talk about what criteria we will use for determining whether 2.4.0 is ready for release. I''ve started configuring a firewall at work with the multiple ISPs support, but its kernel doesn''t have connection marking support, so it''s going to be a couple of

Hello, You may recall some of My Dmz question around Thanksgiving. While I have configured a Proxy arp Dmz. I would like to practice with the routed setup you suggested Tom as your network was simular. Here is one of your quotes "The configuration of eth2 is largely irrelevant but you certainly don''t want to confuse things by assigning any default gateway out of that

Hey Tom, I have successfully set up to servers on a Dmz practice network woohoo :). If I take out the proxyarp option in /etc/shorewall/interfaces Then Dmz can ping outside ip''s on the net but not and of my servers on network 66.224.62.96/27 (Other than its own gateway server 66.224.62.120) The reason I ask is to learn. I thought I would not need the proxyarp option for this to

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

Dear Centos Users: I installed Centos 7 on my server a few months ago. While using ssh, there is always a strange message "Write failed: Broken pipe?. It forces quit of SSH. It?s really annoying as it happens very often with irregular time interval - from a couple of minutes to a few hours. I have been working using Linux (Red Hat, Fedora and Centos) over 15 years. This didn?t happen for me

Good day, I have gone through a couple of the HOWTO''s on how to get this to work, but I am still sitting with a very strange (for me) issue. If two clients connect via OpenVPN (bridged), they can access each other without any problems, but neither of them can access the server, nor any system behind it. I am fairly sure it is a Shorewall issue, but I am very new to Shorewall, having

I have been trying to get DNAT to work and I actually have succeeded too, however, not how I thought it would work when reading through the documentation. 1. No matter what I do I cannot get DNAT to work unless I have an entry in eiter the nat or the proxyarp file. Is that really how it''s supposed to be? I can''t find anything about it in the documentation. 2. Also, in the
