routing via uplink based on source lan?
I''ve got a rather complex beast of a network that I''ve beeing trying to get
properly routed for some time now. I''ve come really close, in that inbound
traffic gets where it''s supposed to, and outbound traffic goes where it''s
supposed to, but outbound packets are all apparently going over the wrong
link.
The system is currently configured as a

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.

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

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 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

Complex Routing/Firewalling/Bridging question
I''m being cast headlong into unfamiliar waters here, and being desperate for
some air, thought I''d come here for some help. :)
Anyway, my employer is going through some whiplash-inducing growth spurts,
and as a result, the simple "Internet T-1 -> Linux Firewall/NAT -> LAN"
setup just isn''t going to cut it anymore.

veto dotfiles but not directory?
I've been playing around a little bit with the "veto files" option for
the [homes] shares we have on our Samba servers (2.2.1a & 2.2.3a).
I've discovered that:
veto files = /.*/
works marvelously for not letting the users muck with their .dotfiles,
which is exactly what we want, however, I've also discovered that it
also clobbers the special directory entries

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

extremely slow delete/move operations?
I've been working to migrate several hundered users on to our new mail
servers, which run dovecot 0.99.11 (RHEL4). The problem I'm seeing is that
deleting or moving a message seems to take a very long time. It's not
uncommon for Thundirbird (1.0.7) to have delays of 5-10 seconds to delete a
single message from my Inbox (<500k) and place it in my Trash folder (~100MB

Shorewall with ProxyARP
Hi,
Thanks for your reply . I am attaching the files needed by you
herewith. The NAT device is called Pronto gateway which has two
interfaces , namely eth0 and eth1. ''eth0'' has an ip address of
203.124.152.66 and eth1 has an ip address of 192.168.1.3 . All the
client PCs are in 192.168.1.0 network [behind the NAT, the Pronto
gateway] and use 192.168.1.3 as the default

1.0 beta3 not preserving X-Keyword header?
We've been putting 1.0 Beta 3 through the paces on our test system, and one
of our users pointed out to me that Thunderbird's "labels" behave strangely
on the new server. In fact, there used to be a header added to the message
via IMAP when Thunderbird placed a label on a message, but as of the switch
from 0.99.11 to 1.0beta3, this label header is no longer placed in the

alternate ports?
I'm trying to set up 1.0 beta 2 on one of our systems, and would like to run
it on alternate ports from the standard IMAP and IMAP/SSL ports so that we
can test it out a couple users at a time. How does one tell dovecot to
listen on alternate ports? I can't find anything in the example config file...
Thanks,
Gregory

Apple Mail cannot connect (1.0 beta3)
I'm testing 1.0 beta3 on our mail server, and finding that Apple Mail seems
unable to connect to it.
I'm running the 1.0b3 on port 997 so we can test it in parallel to 0.91 to
compare performance (so far, it's hella faster). I've ensured that the
users testing are _not_ connecting in any way to the 0.91 version running on
port 993.

Proxy ARP
Hi all!
I posted earlier about the proxy arp configuration =

and was probably not sufficiently knowledgeable on the subject. I''ve =
gone through a bunch of documents on proxy arp, subnetting with proxy =
arp and the documentation at shorewall, and have come up with a setup =

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
