Interface Configuration
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

Dmz
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

Ftp Broken in Dmz
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

Dmz
Hello Tom, I am not sure if you can help with this but I am at my wits end. If you hit this site and do a force refresh (ctrl + F5) the site will time out and lose connections. Do the same on port 443 and it does not time out??? The web site I am reffering to is www.tituswill.com I think the only problem is port 80. Do you have any idea how to diagnose this I have sent a dump of just

Usersets
Is anyone using user sets? I''m considering dropping support for them in 2.0 in favor of just listing individual user/groups in the rules file. Thanks, -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net

New on the Web Site
While I''m in temporary retirement, I''ve decided spend a little time experimenting with new things and making some updates to the web site. The biggest result of this effort to date has been: http://shorewall.sf.net/Shorewall_Squid_Usage.html This outlines how to use Squid as a transparent proxy running on the firewall, in the DMZ or in the local network.

VPN hardware?
I have a NetGear FV318 living in my DMZ, with one of its LAN-ports living in my LOC zone. What rules are needed in shorewall to allow a certain subnet to make connections to this device from the net zone? Do I define it as a tunnel in shorewall/tunnels, or do I just allow some selected traffic to the DMZ IP? I am not sure which of the docs are right for me in this case?

urgent TEQL problem
OK, I spammed the mailing list recently, but I will be fired if I can''t solve the problem today. (just kidding, but I did waste lots of time on it :( ) The common configuration for teql is for two computers connected directly with two links. My topology is a little different: one link is connected directly, but the other is connected through a gateway. My problem is teql can''t

routing and virtual machines: how to access dmz if bridged to two networks
I am not quite sure if this issue relates to iptables, routing or Xen virtual machines. Too many variables for my simple mind, so I'm asking some advice :) This is my network setup: Internet --- eth2 + CentOS dom0 / firewall / router + eth1 (xenbr1) --- LAN with private IPs --- separate file server and workstations + eth0 (xenbr0)

Routing all connections through a OpenVPN tunnel
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

help seeing DMZ from LOC
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

DMZ Recommendations
From reading the documentation, I understand that it is recommended to put servers that may be at risk in a DMZ served via proxy-arp. In this case, the local clients that are behind a NAT would have their connections to the DMZ masqueraded, yes? Is there any way around this that would still be considered secure? Just looking for advice. Thanks, A.

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
