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 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

Hello alltogether, I''m new to the list, so please excuse any violations of listiquette... I didn''t have to much to do with linux based firewalling and routing for quite a time and found that proxy-arp changed in between... As I struggled with it I found that the Advanced routing... howto wasn''t to helpfull. Especially the documentation seems to be rather vice versa to

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings I''m having a network problem that I don''t understand. It involves/hinges upon an internal router running the latest Shorewall. We make weather radar control and networking software. Our customers are experiencing a connection timeout, but here in the office we are not. I have some slight suspicions as to why they see a

Please see https://bugzilla.redhat.com/show_bug.cgi?id=727648 for more info. Shorewall executes some bash code like the following: while read address interface external haveroute; do qt $IP -4 neigh del proxy $address dev $external [ -z "${haveroute}${g_noroutes}" ] && qt $IP -4 route del $address/32 dev $interface

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

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

This will be the last Shorewall release for a while as I''m going to be focusing on Documentation. In this release: 1. Empty and invalid source and destination qualifiers are now detected in the rules file. It is a good idea to use the ''shorewall check'' command before you issue a ''shorewall restart'' command be be sure that you don''t

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

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

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!)

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- 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

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

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

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

Can''t get proxy arp with arp -s <IPaddr> <MACaddr> pub to work with a 2.4 kernel. I see some evidence in the archive that this was broken in the 2.0.x timeframe and never fixed. Anyone know for sure if it''s broken or working ? (I''m attempting to route a few addresses into a routed network, from the ethernet side of a DSL router that has a /29 public
