Shorewall help blacklist and restart/refresh
At the current time I am not subscribed to the mailing list.
I have a blacklist that I got from www.peerguardian.net that is rather
large ( 81 kb).
When shorewall start command is issued it takes about 20 mins for it to
load.
Is this normal or should I do this another way?
Also I noticed something very strange with shorewall ..
I have cron do a shorewall restart command every 24 hours and

Newbie going through a probably stupid thing
Believe me:
Read the FAQ
Checked over and over
This might be toooooo stupid to be documented.
Please bear with me. Any help ?
Situation: single card standalone "firewall" (used like a "personal
firewall"). Have sshd running on the FW. Want the sshd daemon to be

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

Problem getting dcgui-qt to work through shorewall
My dcgui-qt (chat/file-sharing program) doesn''t work and I''m pretty sure it''s my firewall settings.
dcgui-qt is a direct connect (file sharing & chat) client.
According to the FAQ here

SFTP
(anonymous post) I have a simple 2 interface firewall setup and all is
good, almost. I am hosting virtual websites and DNS behind shorewall no
problem. However I am trying to use SFTP via a different port number and
have no luck even though Putty works well. Is there anything weird to
sftp and shorewall? My lab uses a different firewall (firestarter) and
it works OK.
I am using;

Ftp Broken in Dmz
I have had a web server listining sql-1433, www 80,
ftp-21 using proxy arp with sub-netting in a three interface DMZ.
All these ports are in the rules file as ACCEPT.
With one exeception that 1433 allows a few host from
the net. 21 and 80 allow all net to dmz connections.
The policy is DMZ to net ACCEPT
This has been working great for about a month or more until I rebooted

Proxy Arp Ip Conflicts
I must have something configured wrong somewhere. I''ve enabled proxy-arp on my
shorewall 2.0.7 firewall. Works fine for what its supposed to do, I can see
all the machines through it great. However, whenever its enabled, the network
on the DMZ goes screwy. I''ve narrowed it down to this:
when proxy arp is enabled for that interface, like such:

Shorewall problem, perhaps with PPPoE
I have what strikes me as an odd problem with shorewall.
Let me describe my setup.
My desktop (alfred) is connected to the network
through an ADSL modem.
I am running rp-pppoe, and this works perfectly.
I have a small home network, with two LANs;
an Ethernet LAN (including a machine running Windows XP),
and a WiFi LAN, including the laptop (william) I am using now.

newnotsyn responsible for sporadic delays?
Has anyone encountered a situation where packets dropped by the
newnotsyn chain can result in sporadic browsing problems, slowness, and
even timeouts?
I noticed that of the 3300 hits for newnotsyn in our current log (6 hours
worth), over 2700 of them were to/from our proxy servers. And browsing
through them, most *appear* to be otherwise valid packets from remote
web servers that would have

Problems with FTP to one host

sudden I can FTP into the machine, but I can''t "ls" or "put" files. I *can* do
