Squid
I''m attempting to setup Squid as shown on:
http://shorewall.sourceforge.net/Shorewall_Squid_Usage.html#DMZ
The firewall is a Bering 1.0 firewall running Shorewall 1.3.11, Red Hat
7.2 on the server in the DMZ. I''m not seeing the requests come in to the
server using tcpdump. The server is 192.168.2.1 connecting to eth2 on the

DHCP
Good day to all.
I don''t like to Post unless I am really stuck. Guess what?
Redhat with Shorewall. Been using this for years. I have a new client that we have setup with Redhat and Shorewall. The problem is that his outside address (ETH0 = NET) is dynamic (i.e. DHCP enabled).
All the rules work fine when we use a STATIC address on Eth0, so we know the rules, filters, tos etc work fine

BitTorrent uploads enabled?
I''m seeing what may be sort of strange behavior - My machine is behind a
Shorewall firewall, which, in the rules section, includes:
AllowBitTorrent, any source, any dest
I''m wondering - how is my machine behind the firewall able to upload, since
no port forwarding related to bittorrent is taking place? (Just to clarify -
it IS uploading)
I looked at the AllowBitTorrent

alternative nameserver from local network
hi,
I have a debian system with shorewall acting as a router between my adsl
line and my local network. One of the things on that local network is my
playstation, and I''m having trouble playing an online game with it - the
game tries to access the internet, and then fails at the stage where it
tries to find the game servers.
The debian machine is 192.168.0.3, and the playstation is

I apologize for the first message. :)

linux-ha heartbeat .. failover firewall
I have searched your FAQ''s and read the documentation on your site as well
as googling. I am not able to figure this out. If you have any ideas can
you please help.
I am using the linux-ha failover with redundant firewalls.
As part of the function of the linux-ha software consists a service called
heartbeat which is a connection from each failover node through a serial
cable or ethernet.

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.

problems/questions.
My basic set up is: 1500/256kbit ADSL (PPPoE/ppp0) -> Shorewall box

Wondershaper stops limiting outbound traffic
I have wondershaper to limit my upload at 400kilobits (my line is 600kbps).
I do a lot of torrent seeding and I dont want my pings killed when I''m
uploading so I set low prority source ports as follows (by the way, I have
bittornet to only use ports 6881-6910):
NOPRIOPORTSRC="6881 6882 6883 6884 6885 6886 6887 6888 6889 6890 6891 6892

Is it that difficult?
Hello,
You will find in attachment the layout of my
current physical configuration.
For now, the Cable ISP is not used. Since it
is a dynamic ISP, my mailserver is rejected and
my domain name registers on blacklists like ORDB
and al.
I want it to be used as a default gateway except
for my mail server that would be seen as coming
from my "honest" ADSL ISP.

Two Interface Setup + router problems II
Hey all, A while ago today I posted about not being able to get my two
interface setup working with a router (di 652 wireless/wired). I
recieved help from Tom and got everything in the router turned off and
set it up as a switch rather then a rouiter, this still never
corrected my problems. Use tcpdump I see there is alot of traffic, but
as soon as I dhcpcd eth1 (local) I loose all outside access

Connection problem
I've got a test lab set up and im having problems connecting.
The first problem is that it takes it a couple of tries before it actually
connects the two machines.
It complains about bogus data and after trying for a minute or so it
connects.
kill -USR1 shows that they are connected
kill -USR2 only shows the local subnet, not the remote

Not able to access website
Hi,
Trying to figure out why I cannot get access to dell.com
Their site is up because I can browse using a different firewall.
Trying to find out where the logs are located and what log files it
would write to if it were to deny browsing to a website. I can see the
[UNREPLIED] when using the shorewall status. Was hoping to know what
logfile it is writing it to.
Thanks in advance,
