Hello, I have searched the list but couldn''t find the right answer. I want to drop an established DNAT connection but could not manage it yet. Someone earlier said to bring down the public interfaces, stop shorewall, bring up the public interface and then start shorewall again but this won''t work. I also saw a message from Tom that someone then should unload all iptables

I want to run dhcp and shorewall on the same computer.It is my gateway and that computer doing NAT for my network.How can I set up shorewall to let only users that get theire static ip address via dhcp, not to let users that had static address.

hi all, i have a classic net topology with two local zone, a firewall/router with dsl connection loc1 (192.168.11.0/24) ----- fw ----- net loc2 (192.168.12.0/24) now on the local zone 1 (on a WinXP machine) i have installed OpenVPN 2.x to make a test connection with a company. OpenVPN is configured as client to use tun on udp port 10000 with ip 10.0.0.2, on the other

The basic functionality of Shorewall 2.2.2 works fine with the soon-to-be-released SuSE 9.3 (I have an early copy). I''ll be trying it over the weekend with more complex configurations involving IPSEC and OpenVPN. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \

I am making a new box to test with and was trying to install shorewall via rpm. So I download the shorewall 2.2.5 rpm and issue a rpm -ivh shorewall-2.2.5-1.noarch.rpm. I then get an error: error: Failed dependencies: which is needed by shorewall-2.2.5-1.noarch So as you can see there are no dependency issues. I thought I saw this on the mailing list a while ago but I just searched for it I did

Although 1.4 is now released, there is one aspect of Shorewall''s design that I''m still quite unhappy with. It involves two areas: a) when and when not to create rules to allow inbound traffic on an interface to be routed back out that same interface. b) intrazone traffic. I''m currently running 1.4.0 plus a change that: a) Allows intrazone traffic unconditionally --

Hello, I have forwarded this to the shorewall-users list. You will find better support for this obscure problem there.

First off, I want to say that everyone on this list is great. So heres what I want to do..I have a maclist setup with all my users (roughly 400). There are constantly people leaving (deleting their accounts which removes their MAC address) and registering for internet access ( I have a php webserver that registers them, adds them to the maclist, and allows them on the net). Is there a way to

Setting up MAC Verification on eth0...

how to make this work, its seem to me that netfilter is changed more or less someplaces that shorewall do not support, using 4.4.27 shorewall and shorewall6 suggestion welcomed ------------------------------------------------------------------------------ Try before you buy = See our experts in action!

Hy, sorry for my poor english i think i''m having a very unusual problem and very dificult to track, but i''ll try to explain it as best as i can. here is my scenario: a firewall/bridge composed of 3 ethernet devices and 1 virtual one. my bridge (br0 ) is composed of eth0, eth1 and tap0 br0:eth0 is my connection to my router (200.244.92.1) br0:eth1 is my connection to my

Hello, I''m a very happy user of shorewall but I have found a problem or maybe a misconfiguration I made which I can not resolve. I use a fairly large blacklist based on probes, nimda & codered attacks, proxy & relay probes etc. The only problem is that I want to block incoming trafic on all ports FROM a block but it does also block a httpd, ping etc TO a ip in a block what I do

Hi, At the moment I am controlling my LAN client access to the Inet by their MAC address. Currently I am putting their MAC address in the rules file - now the number of the PC that I want to manage is getting more and more and it is not practicle to do this way anymore. My question is, how can I have their MAC address in other separate file? Regards http://www.debian.org/consultants/#Malaysia

Hi, I want to automate some of the maclist and rule functionality: User connects to the network and gets a DHCP address from the shorewall box. Using squid and redirection, all the user can do is go to a login page on the firewall User logs in correctly to the form on the webpage and a process captures MAC and IP address info from the dhcpd.leases file Once authenticated, a maclist entry and an

Hi, I have a few problems with my shorewall configuration. First of all, the option maclist seems no to be recognized. I have this: ghostwheel /etc/shorewall # cat interfaces | grep -v ''^#'' - eth1 detect dhcp,tcpflags,routefilter loc eth0 detect tcpflags,maclist When I look at shorewall-init.log, I found out:

hi there. There are approx. 400-500 users in our network and we plan to insert all their MAC addresses into maclist and bind them together with IP address. My question is whether shorewall is able to process that much of MAC addresses without slowing the the network speed performance? thanks for your time. __________________________________ Do you Yahoo!?

Tom, or whomever reads this, when I say disconnect I mean close out IE6, sorry for so unclear on this point. My IP address never changes unless I unplug the modem. I have had the same IP address for ... well since I had to reset it to hook it up to my Linux box.which was 2 weeks ago. If I set DHCP on my eth1 interface that will contradict the static address I have assigned to it,
