similar to: Accounting Proxyarp users !!?

Hi- One last question for the week, I promise. I''ve got one IP ProxyArp''d according to the instructions at http://www.shorewall.net/ProxyARP.htm. I''ve setup the shorewall/proxyarp file as follows: #ADDRESS INTERFACE EXTERNAL HAVEROUTE PERSISTENT 208.4.145.73 br0 eth1 no yes #LAST LINE -- ADD YOUR ENTRIES

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!)

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?

Does anyone know what a good maximum number of machines I should place in the ProxyArp list? Thanks Jamie

Hi As per my follow up mail I implemented the ProxyArp configuration as per the Documentation on the Web site and all seemed to be working correctly. However, the one thing that doesn''t seem to be working properly is Samba. I have Samba running on the FW machine and one of the servers 192.168.0.8 on the Local Lan. I can connect to a Share using Samba from Server to Server, however

Hello Shorewall gurus, I have a dilemma with a public server. I want to migrate the current public server over to a new machine behind the current server''s firewall (shorewall 1.4). I have included a diagram below to help explain the target network I am working toward. I have read the shorewall online documentation and though I have used Shorewall the past 4 years in the current

Would it be considered normal that a system behind a shorewall box that was setup for proxyarp and able to be reached from the trusted side of the net just fine on the proxyapr ip address would if it were to talk out to the world show as traffic not from the proxyarp address but the firewall''s own address or the masquerading ip used by other zones? We had not really noticed this as an

Hi everybody. I''m trying to configure shorewall folowing this manual: http://www.montanalinux.org/proxmox-ve-with-shorewall.html But with shorewall check it tells me thah: Checking /etc/shorewall/interfaces... ERROR: Unknown zone (dmz) : /etc/shorewall/interfaces (line 16) How can I define it in the zone file? thanks for the help. best regards, Santiago.

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''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

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

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

I have a Windows 2008 domain (one Win 2008 DC, one Win 2012 R2 DC.) I am trying to join a Solaris 11 machine to the domain for both Samba and other services. For "unix" logins and ssh, Solaris 11 is configured to use LDAP for user and group lookup and kerberos for authentication. The "kclient -T ms_ad" command joins the Solaris machine to the AD domain. It even

Hello, I am having troubles with the following configuration in that it produces the following errors: *Masterserver:* On the server (yea, I know) side is a Linux machine called "*masterserver*". It should have a VPN IP of 192.168.2.1 and it sits behind a pretty generic ADSL Router (with port 655 forwarded) which can be found via a dynamic host address. A small snippet of errors this

Hi Folks, Can i transform my firewall into a bridge (Mean Nic to Nic), in the ethernet level (Not protocal, Ip''s etc) and also use shorewall ? Than make a Layer 2 Switch with netfilter rules to all Ip''s in my network ? I have 4 whole real classes and want to protect the people inside. With proxyarp works but sometimes fail (People loose connection etc) Just with switchs and my
