I have a dsl modem and two static IP addresses: 66.17.65.22 and 66.17.65.161. I am using the standard configuration from the Shorewall Setup Guide for multiple IP addresses and modifications suggested by the Aliased Interfaces Guide. I want to set up a shorewall 2.08 router for my home (Fedora Core 2 / kernel 2.6.8-1.521). I want share an internet connection with some pc''son a local

Hi Guys, I have been trying to configure shorewall 1) Internet Access to internal users 2) Have a DMZ that will house atleast 6 mail / web / ftp servers that will server our existing group companies outside our physical location. 3) Setup openvpn between our location and our group companies .

Hi, I install shorewall firewall on my server and after that I have big problem with SMTP, I can send messages with outlook to server but that messages don`t go out from server (Currently I have over 800 messages in the mail queue) My server is on WHM/cPanel and EXIM.... When I click on "Delivery Now" for some message in WHM I get error: Message 1BtoLi-00033G-RN is not frozen LOG: MAIN

Hi, just cracking my head how to solve this: Firewall has more than one public IP Address and NET/LOC/DMZ configured. Requests on public 1.1.1.2:80 should go to dmz:192.168.0.1:80 Requests on public 1.1.1.3:80 should go to dmz:192.168.0.2:80 How can I manage that with DNAT? I tried it with the original destination, but keep getting "REFUSED" always for one connection. Thx Andy

As I received no response on the general CentOS list, I'll repost it here as the question is about Xen virtual machine routing. This is my network setup: http://pastebin.com/kyWpTQYU Lets assume my dom0's eth2 public ip is 1.2.3.33 and my dmz network 11.22.33.96/255.255.255.224 . I have created NAT from my LAN with iptables. You can see my /etc/sysconfig/iptables here:

I have a three interface network (net,loc,dmz). The internet interface (eth0) has a static IP. Windows machine in the local network (eth1) use DHCP to get IPs from the 192.168.10.0/24 netblock. The Debian machine in the DMZ (eth2) gets a fixed IP through DHCP in the 192.168.11.0/24 netblock. The DHCP server is running on the firewall machine (not ideal, I know, but that''s the way

I made a boo boo in my config and put in this rule #PPTP DNAT net:213.67.241.162/217.209.46.204/32 loc:192.168.221.200 tcp 1723 DNAT net:213.67.241.162/32,217.209.46.204/32 loc:192.168.221.200 47 - And the the following happened.. and I wonder why it didn''t complain? I am sure I am just misunderstanding some doc

Thanks all for the response to my problem. Outside interrupts made me set aside the project temporarily. Reading your input (one email of which was rejected by our email engine for reasons unknown) the thinking seems to be that Apache can''t resolve its virtual hostnames. I had not originally installed the dnsmasq module, so did that. However, there was no difference in performance. I

Hopefully this is an easy question.... I''m using a leaf router (bearing) running shorewall. Three interfaces net, loc, and dmz. Only one computer in the dmz and its being proxy arp''d. External and internal (net and loc) can reach the dmz but the dmz cannot reach the isp''s gateway and beyond, but can reach a system adjacent to the firewall.

My sincere apologies to all on this list. After looking for returning packets with tcpdump and not finding ANY I called our provider to confirm our IP assignment. The IP range that I was given by my boss was incorrect. After adjusting the ip assignments, everything is working perfectly. Thank you all for your time in troubleshooting this, and I hope to be able to return the favor at some

Hello all, I''ve read the shorewall guides and browsed through the mailing lists, but I haven''t been able to find out if the following is possible or not using shorewall. Our provider has given us 16 IPs + 4 in a separate range for our uplink. I would like to replace that router with a Linux box running shorewall with three interfaces. I want the DMZ to be a standard, routed

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

I have an access-IProm my isp that I configured my eth0 with. And I also have an IP-range assigned from my ISP that will be used on my servers connected to eth1. The IP-range is routed thru the access-IP. This is how my configfiles look like. Internal everything seems to work but not external. /etc/shorewall/proxyarp #ADDRESS INTERFACE EXTERNAL HAVEROUTE

Hi all; We have a Solaris 10 U9 x86 instance running on Silicon Mechanics / SuperMicro hardware. Occasionally under high load (ZFS scrub for example), the box becomes non-responsive (it continues to respond to ping but nothing else works -- not even the local console). Our only solution is to hard reset after which everything comes up normally. Logs are showing the following: Jan 8

Hello list, I am in the process of switching from IPCOP to Shorewall s the firewall for our small office. I very much like the fact that Shorewall runs on top of the same OS (openSuSE 11.4) that I run on the server and my desktop. Our setup is fairly straightforward. We have 8 static ip addresses from our ISP, which provides a cable modem and a Cisco 800 series router. The ip addresses are

I am trying to add a machine into my dmz. It is the first machine I''ve ever added to this dmz and fro some reason I cannot establish communication between the dmz and the machine. Here is an example of my setup: ISP router --> firewall (eth0) firewall (eth1) --> local network firewall (eth2) --> DMZ eth0 and eth2 have public IP addresses as does the machine I just added to

Greetings all, I''m a bit of a linux rookie, but a friend and I have built a firewall running Shorewall 1.4.6c over a minimal install of Redhat 9. Out network setup looks something like this: Cable Modem : eth0 :12.xxx.xxx.3 (Zone is named INSIGHT) Campus Lan : eth1 : 10.176.9.21 (Zone is named MULAN) DMZ : eth2 : 192.168.1.0 255.255.255.0 (Zone is named DMZ) Currently, I
