similar to: shorewall and proxyarp ?

I have some hosts in a DMZ zone with proxyarp. In my local zone I have a host to which I DNAT. I have discovered that I can reach the host in the local zone by attempting to connect to the fw (As expected) or ANY proxyarped host in my dmz zone (as not expected). Is this normal ? (I''ve just discovered that actually the dnated host answers to requests sent to any IP routed to my host!)

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

Hi, Thanks for your reply . I am attaching the files needed by you herewith. The NAT device is called Pronto gateway which has two interfaces , namely eth0 and eth1. ''eth0'' has an ip address of 203.124.152.66 and eth1 has an ip address of 192.168.1.3 . All the client PCs are in 192.168.1.0 network [behind the NAT, the Pronto gateway] and use 192.168.1.3 as the default

I´ve figured out the following. I am able to sftp from shorewall 2.4.2 left vpn gateway x.x.x.14 (DMZ) to shorewall 2.4.1 fw x.x.x.11 with /etc/shorewall/proxyarp x.x.x.14 eth2 eth0 No very well. That´s not through a tunnel (of course a ssh tunnel, but no vpn) but with public ip x.x.x.14 to x.x.x.11 If I try to sftp through the fw to the public internet I have the same

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

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

Hello All, I have a question about setting up the shorewall firewall for squid, I followed the instructions on "Using Shorewall with Squid" --> "Squid Running in the DMZ" section. For some reason I am unable to get the program to work. I am able to have the squid work properly by using squidclient program, but once I setup the firewall to use the redirect I am unable to

I''ve got a serious mess of NAT on our firewall/router systems at the corporate office which seems to do nothing other than confuse the heck out of people. What I''d like to do is gradually migrate the hosts on the various DMZ networks away from private IP addresses and NAT over to public IP addresses and proxyarp. What I''m wondering, before I start this, is how do I

Hi, In a routed network setup , is it possible to use ProxyARP given the condition that the shorewall external interface and the DMZ interface are in a completely different network . That means the gateway of the External interface and the hosts in ProxyARPed DMZ zones are in different network. eth0 ---in 220.227.X.Y/30 -- shorewall external interface eth1 ---in 220.227.A.B/27 -- shorewall

My ISP has DHCP-assigned IP-addresses. I wonder if someone has tried using proxyarp for a DMZ with DHCP-assigned public IP?

Dear list, I''m running Shorewall on a dedicated Fedora 7 box. Shorewall is working well as an office DSL router (dynamic IP) with loc and dmz zones. I am now trying to configure IPSec to connect a VPS, "casp", with a static IP to both the firewall and to the loc network behind it. The host to host SA works fine. However, pings from "loc" to "casp" can be

Hi, I''m seeking advice for the following setup. Shorewall 2.2.2, debian/sarge on Soekris net4501 boards. We have two ISP feeds (let''s call them ISP-1 and ISP-2) and get 8 static IPs with each feed. The plan is to have the publicly accessible servers sitting in the DMZ connected to ISP-1. Our local intranet (LOC) will be connected to ISP-2. There will be 3 firewall/routers: fw1

Hi everybody.

I have a dsl modem and two static IP addresses: 66.17.65.22 and 66.17.65.161.

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

If you have a working proxyARP setup, will you please post it? I''ve tried to insert a Linux box between the DSL connection and the switch, but I''m getting nowhere. Everything works correctly when all the servers in this network use the switch to get to the DSL. Any box directly connected to the DSL also works correctly. http://www.sjdjweis.com/linux/proxyarp/ makes it sound

Hi, I have a 3 interface FW like this: http://shorewall.greshko.com/GSLUG_files/slide0008_image004.png where I use PROXYARP to give the servers in DMZ an IP from our public IP range. A bit like this: http://shorewall.greshko.com/GSLUG_files/slide0042_image026.png proxyarp: xxx.23.52.145 eth1 eth0 - yes xxx.23.52.146 eth1 eth0 - yes xxx.23.52.147 eth1 eth0 - yes xxx.23.52.148 eth1 eth0 - yes
