Port forwarding on Shorewall box behind NAT ADSL router
Hi,
Before I go any further, I''m no networking expert, and the sheer volume
of documentation on the Shorewall website makes my brain hurt..
Some time ago I moved from an area with cable internet to an ADSL only
area. While on cable, I''d set up an old P3 box running Gentoo as a
firewall/gateway/file server, running shorewall (currently v2.2.3) and
dnsmasq. I''d

Norfc1918 Blocks all (even with additional rule)
Hi
I had this problem that shorewall blocks all traffic
from net when norfc1918 rule is given to my eth0 (net
ethernet card).
I''ve added: run_iptables -I rfc1918 -s 192.168.7.10 -j
ACCEPT
To start file but that didn''t help.
My configuration: ADSL modem has static 10.***.***.***

Snapshot 20030629
Problems Corrected:
1) A problem seen on RH7.3 systems where Shorewall encountered start
errors when started using the "service" mechanism has been worked
around.
2) A problem introduced in earlier snapshots has been corrected. This
problem caused incorrect netfilter rules to be created when the
destination zone in a rule was qualified by an address in CIDR
format.

All kinds of traffic from net - > dmz, nothing gets REJECTED or DROPED
and Here is my rule that did this
DNAT net:eth0 dmz:62.103.xx.101 - - - 62.103.xx.105,103.xx.106,...
What I was trying to achieve:
Since I am only using 3/16, I wanted to fake the rest of them as being
alive hosts. Only to accept pings and some allowed protocols accessed
from the net.
What is wrong with my rule?
Will REDIRECT work ???

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.

I guess I just overread the part I need, I checked the FAQ and
online-documentation, but could not find the solution for my problem:

Port forwarding/DNAT of broadcast packets?
Hi folks,
Has anyone out there done port forwarding or DNAT for UDP packets that
are normally sent to the broadcast address (255.255.255.255)?
I have to support a nasty database application called FileMaker Pro
(those of you who know it are probably groaning about now), which uses
broadcasts to locate the database server. Theoretically, i can get
around this requirement by using LDAP lookups

MAC Server support
Hi all,
I needed to have a kind of MAC support for rule servers as I do DNAT to
hosts that are
served by a DHCP server.
So I did the following :
When Shorewall script find a MAC address as a server, it tries to get his
IP thru the
arp table and then "resolve" the ARP address to the IP address of the client.
Of course the main limitation of this is that you''ll have to
