Is ProxyARP or NAT entries really neccesary for DNAT to work?
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

Problems With NAT/Multi IPs Settings... Shorewall 2.2
So I am trying to get a firewall up at work using Shorewall 2.2 / Mandrake
RC 1, where we have multi-ips assigned to a single machine....
Now at one point I had Shorewall and Mandrake configured and it was
working... this was our setup essentially (I''ll use 192.0.0.x as out
external IP addresses)
In ifconfig:
eth0 192.0.0.202 nmask 255.255.255.248
eth0:1 192.0.0.203 nmask

In the Mandrake control center, the options for DNS Servers get wiped out...
I think this is just a Mandrake issues. Was just the one issue that got me

DNAT, NAT or ProxyARP?
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

Samba and ProxyArp
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

ProxyARP in a Routed environment
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

config question for proxyarp hosts?
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

proxyarp and masq ip
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

odd problem with proxyarp and DNAT
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!)

Proxyarp vs DNAT
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

OpenVPN and DNAT
Hello Tom and all,
Quick question: Is it possible to operate an OpenVPN server from behind
a firewall?
Is it as simple as setting it up and placing:

"Multiple Internet Connections" with four interfaces
Hi,
I was reading document http://shorewall.net/MultiISP.html#idp3634200.
Inspired by the document I was trying to establish the following changes:
* one additional interface: COMA_IF
* COM[A,B,C]_IF interfaces request IP address via DHCP
* all non-RFC 1918 destined trafic is NATed from INT_IF to COMA_IF
* all non-RFC 1918 destined trafic from GW is routed via COMB_IF by default
* non-RFC 1918
