Rate limiting
I am trying to rate limit a particular user/ip''s news traffic and have added the line ACCEPT loc:10.5.75.253 net tcp 119 - - 1/sec:2 While this has slowed down the traffic, it has not throttled it to the point I would like. Yet with a sniffer I can see around 15 packets a second going thru. My T1 is close to saturation, and I would like to

Bug in Shorewall check?
I made a boo boo in my config and put in this rule #PPTP DNAT net:213.67.241.162/217.209.46.204/32 loc:192.168.221.200 tcp 1723 DNAT net:213.67.241.162/32,217.209.46.204/32 loc:192.168.221.200 47 - And the the following happened.. and I wonder why it didn''t complain? I am sure I am just misunderstanding some doc

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. 2. Also, in the

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!)

DNAT Issue
Hi. Im setting up a web farm test lab. I have a number of machines in the test last on a dmz zone on network 10.20.30.0. The test lab firewall has two NICS. One (eth0) has two ip addresses, eth0 10.161.101.40 and eth0:0 10.161.10.49. The other one, eth1 is on a private network, 10.20.30.0. I want to use DNAT to allow test engineers to ssh into the machines in the web farm. I have

Reflecting internal connections to public IP back into network?
I''ve got a Shorewall firewall setup that''s similar to the standard 3 interface configuration (net,loc,dmz). Several ports are forwarded from the internet to computers in the dmz. I''d like to have any connections to that same public IP address from either loc or dmz to be treated exactly as if they were coming in from the internet itself. There''s some

Confused about approach
Greetings all, I''m a bit of a linux rookie, but a friend and I have built a firewall running Shorewall 1.4.6c over a minimal install of Redhat 9. Out network setup looks something like this: Cable Modem : eth0 :12.xxx.xxx.3 (Zone is named INSIGHT) Campus Lan : eth1 : 10.176.9.21 (Zone is named MULAN) DMZ : eth2 : 192.168.1.0 255.255.255.0 (Zone is named DMZ) Currently, I

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. I''ve turned

DNAT e.g. port 80 to different hosts
Hi, just cracking my head how to solve this: Firewall has more than one public IP Address and NET/LOC/DMZ configured. Requests on public 1.1.1.2:80 should go to dmz:192.168.0.1:80 Requests on public 1.1.1.3:80 should go to dmz:192.168.0.2:80 How can I manage that with DNAT? I tried it with the original destination, but keep getting "REFUSED" always for one connection. Thx Andy

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

interesting problem
I have shorewall 1.3.12 installed on a redhat 8 fully patched machine with three nicks. Eth0 has 10 IP''s bound to it and has been succsessfully routing web traffic to servers on the dmz. This morning I added another server to the DMZ, configured my network with the correct IP, configured dnat in "rules" and restarted both. From a standalone machine that is on the same segment

FORWARD:REJECT
I have a 3 nic setup with shorewall 1.4.8-1 running on redhat 9. My eth2 (dmz zone)has 7 secondary address attached to it.
