dmz setup
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

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

Using private & public addresses together i n the Shorewall''s DMZ zone
To rephrase the question, "Can I use masquerading and proxy ARP in the same zone simultaneously?" It''s not a stupid question--I couldn''t see any reason why it wouldn''t work, but I had actually try it out to convince myself that it did (which isn''t a bad thing to do before posting the question to the list, by the way). In any case, the answer is

mail server in dmz
Hi, in a three interface firewall I have eth0, loc, 10.1.5.1/16 eth1, int, 200.41.61.228/29 eth2, dmz, 192.168.1.1/24 (un)fortunately I got a group of public ip?s to use, so here is my problem in the dmz I have 192.168.1.3 redirected from eth1 alias 200.41.61.226 (a web server, works perfect). I am trying to set up a mail server also, a different machine, so I can?t use proxyarp, as with this,

Idea: permit /etc/shorewall/masq to contain zones, as well as interfaces
Dear All, Firstly, thank you very much - shorewall is great. I''m not a member of this list, and please forgive me if I am suggesting something stupid, but the following occurs to me, and I thought it might be useful. Why no make it possible to specify zones as well as interfaces in the /etc/shorewall/masq file ? Eg: instead of: eth0 eth1 one might write: net loc (or masq in

Multi-Hop VPN Issue looking for Solutions
I''ve just discovered that I do not have access to the remote gateways for a set of IPsec tunnels to remote networks. This prevents me from changing the routing table on those gateways. I need "roadwarrior" systems connecting to me local network using OpenVPN (tun) to be able to access those systems. Since the remote gateways don''t know about 10.100.1.0/24, where my

Not sure how to configure Shorewall 2.1.3
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

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.

Proxy ARP
Hi all! I posted earlier about the proxy arp configuration = http://shorewall.sourceforge.net/shorewall_setup_guide.htm#NonRouted, = and was probably not sufficiently knowledgeable on the subject. I''ve = gone through a bunch of documents on proxy arp, subnetting with proxy = arp and the documentation at shorewall, and have come up with a setup = that would be perfect for the job at hand

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 hosts gateway
Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

Shorewall DMZ - Proxy ARP or Static NAT
Hi All, >From the documentation I have read on Shorewall, the preferred approach seems to be, to use Proxy ARP instead of Static NAT for hosting web servers in the DMZ Zone. But I have also read that this could cause problems for VPN configurations. I essentially have multiple public IP''s, which I want to map to private addresses in the DMZ. I also intend to setup a gateway between 2

Setting up a routed DMZ
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
