Our VPN runs for 3 months very well with a minimum of traffic <100 kbit/s. Only DNS Zones and nagios passive checks were transferred. Everything seems to work. Left side is x.x.x.14 (host 1) Subnet 10.0.0.0/24 openswan 2.4.4 shorewall 2.4.2 & iptables 1.3.4 gentoo 2.6.12-r9 with policy match It´s reachable through a proxyarp entry on x.x.x.11 (host 2) which is another gentoo 2.6.12-r9

Shorewall can run without openvpn, but you need it if you want to establish private networks through public structures. -----Ursprüngliche Nachricht----- Von: info@kws-netzwerke.de [mailto:info@kws-netzwerke.de] Gesendet: Freitag, 30.

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

Hello all, I have a question in regards to proxyarp and shorewall, I am new to shorewall and I have 5 static IP address from my ISP. My current setup is that I have one system with three network cards, (eth0 = xx.xx.xx.42, eth1 = 192.168.110.41 eth2 = 10.10.10.41), two systems with two network cards, (eth0 = xx.xx.xx.41 and eth1 = 10.10.10.42/44), I want to get rid of the eth1 of the two systems

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- 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 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 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 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

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''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 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?

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

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

We had a running ipsec shorewall system to all of our remote offices. We added a dmz to the firewall and implemented proxy arp for that dmz. We have checked everything two or three times and cannot figure out why the vpns will no longer come up. We are using shorewall version 2.2.3 from the debian stable sarge distribution. We noticed the errata that for 2.0.0 there was a problem with proxy
