Strange DNAT problems with shorewall 1.4.8
I''ve had some issues with my network, and I''ve had to reconfigure my
Gibraltar CD. It runs shorewall 1.4.8, and I have a 2-interface setup, so
I downloaded the relevant files from the install page.
Masq and such works, but I''m having a problem with my port forwarding. It
works for port 22, but it doesn''t seem to work for any other port.

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.

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!)

DNAT Issue
Hi.
Im setting up a web farm test lab. I have a number of machines in the
test last on a dmz zone on network 10.20.30.0.
The test lab firewall has two NICS. One (eth0) has two ip addresses,
eth0 10.161.101.40 and eth0:0 10.161.10.49. The other one, eth1 is
on a private network, 10.20.30.0.
I want to use DNAT to allow test engineers to ssh into the machines in
the web farm. I have

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

Shorewall as a "commercial" firewall
I am considering replacing my old checkpoint and watchguard firewalls witha
single Linux box using iptables and shorewall. I have two ISP''s (with
separate routing tables), two DMZ''s, at least one VPN to a remote office, and
a local trusted network. The configuration will look like:

DNAT e.g. port 80 to different hosts
Hi,
just cracking my head how to solve this:
Firewall has more than one public IP Address and NET/LOC/DMZ configured.
Requests on public 1.1.1.2:80 should go to dmz:192.168.0.1:80
Requests on public 1.1.1.3:80 should go to dmz:192.168.0.2:80
How can I manage that with DNAT?
I tried it with the original destination, but keep getting "REFUSED"
always for one connection.
Thx

Shorewall + IPsec Tunnel
Hi everyone!
First of all, sorry about my bad English and the e-mails extension.
I need some help to implement a VPN connection using shorewall and openswan
as IPSec Tunnel.
My network map:
CLIENT VPN APPLIANCE --> +++INTERNET+++ --> FIREWALL --> OPENSWAN SERVER
(DMZ)
I have two VPN connections with two different subnets to the other end. The
two of then are correctly established.

DNAT IP-Adding
Hello List.
I''m new here,
and am staring off with a pretty common question, i think.
I want to have my router DNAT incomeing connections for other IP''s than it''s
WAN IP.
In my other setup, just adding that IP as Destination Address was enough.
But that was a bit older Version of Shorwall.
In my new Setup, Shorewall 2.0.7 Debian Sarge, i have this line:

PREROUTING - DNAT with iptables for an ASTERISK BOX
Hi,
I am running a ASTERISK BOX behind a firewall. It is at DMZ .
Now I want to connect to my ASTERISK BOX from Internet. So I want to DNAT.
How can I do it?
Pls assume that ip address that connects to Internet on firewall is
1.2.3.4and is attached to eth0.
And ASTERISK BOX is 192.168.101.23
Then, What is the rule (PREROUTING) for it? What is the port to DNAT?
I think udp 5060. So I have

macro for dnat through alternate public ip (alias)
Hi,
I have a rule:
DNAT net dmz:a.b.c.d tcp 25 - k.l.m.n
The problem:
I want to DNAT port 25, 143, 110
k.l.m.n is alternate public ip (using vrrp, just like alias)
Can I abridge the above line using macro, instead of writing 3 separate lines?
I can do:
MailPorts/DNAT net dmz:a.b.c.d
But this refer to the physical public ip

DNAT "without" SNAT?
Hi!
First of all, let me say a big "thank you" to Tom for creating
shorewall. I''ve been using it for a few months now and it''s such a
relief to not have to resort to OpenBSD''s pf (which is so much more sane
than Linux'' iptables madness) for the most basic firewalling tasks.
I have a question that I didn''t seem to be able to find in the FAQ.
