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. I can ping a machine in each subnet, dmz to net rules seem to be working fine on all machines.. I have my policy set as dmz to dmz accept. If I try to ping between subnets I get Nov 21 12:18:45 kbeewall kernel: Shorewall:FORWARD:REJECT:IN=eth2 OUT=eth2 SRC=172.17.0.2

I am trying to get a debian system with openswan 2.2 shorewall 2.1.11 + debian kernel 2.6.8 working together. I have read the documentation (IPSEC using Linux Kernel 2.6) and before I go and compile my own modules I would like to know if the standard debian kernel already has the Netfilter+ipsec patches and the policy match patches installed. Does anyone know? thanks Jim

I''m getting my zones confused. Help. I need to have a bunch of systems using OpenVPN to gain an IP in the virtual subnet 10.100.1.0/24, on interface tun0. I will then route whole subnets to those IPs, like 10.100.2.0/24 via 10.100.1.12, etc. I want to have a policy for: - all hosts behind tun0 - all hosts in 10.100.1.0/24 - individual subnets being routed through IPs in

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

I have had to replace an existing setup which has a bunch of IPs Proxy-NAT''ed onto the loc segment. While I do eventually want to move them to their own segment, I have to deal with this for the next few weeks. My problem is that from a loc system I can ping the public IP of a system being proxy-ARP''d but I can''t hit it via HTTP. Nothing is being blocked according

Hi I have recently reconfigured my system to a Bridge based architecture on the basis that I have an ADSL Modem/Router with a Public address on the Wan side and a Private address on the Lan side. I am running a Debian based system kernel 2.6.7 and the Bridging software is installed and working correctly, including startup etc. The problem that I have is in "shorewall start" The

The bridging documentation (http://shorewall.net/2.0/bridge.html) has been expanded and there is a refresh of the bridging code (ftp://shorewall.net/pub/shorewall/Bridging and http://shorewall.net/pub/shorewall/Bridging). -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net

Hi folks, As you''ve no doubt noticed incoming spam recently massively increased. This has overloaded our current server (24.74.9.226) which does HTTP, SMTP, POP and IMAP. To help cope with this, I''ve put up a second server (24.74.9.225) which will be the mail server, leaving the original server to just be a web server. Can I use shorewall on the first machine (version

Great piece of software there... Just a few minor problems. First, the sourceforge site doesn''t seem to be kept up to date. This should be pointed out more (Sourceforge probably shouldn''t be the first mirror either). It caused me some long hours trying to solve a bug in 1.4.6, thinking this was the latest version, when in fact this bug was solved in 1.4.8 (routeback for if+).

Has anybody on this managed to get ChilliSpot and Shorewall to work together? I have managed to get it to work with the supplied firewall script but if I wanted to do my firewall like that I would not be using Shorewall. At any rate, I am having all kinds of trouble translating the supplied rules to something that Shorewall would understand. If anybody has already done it I would love to see the

Hello, I''m not sure if this has been asked before but I would like to ask assistance for this problem I have. I installed gentoo for my firewall/gateway and installed dhcp and shorewall. Currently, I can ssh, ftp, remote desktop connect, ping, etc (anything I can think of) from an internal computer inside my network to an external IP, except I cannot surf the net. I can ssh/ftp to

(I''m not a member of the list at the moment so please answer this e-mail CC to my personal address.

The problem is that appart from the bridge between these I need to share an internet connection and the cable modem assigns me a

Good day, I have gone through a couple of the HOWTO''s on how to get this to work, but I am still sitting with a very strange (for me) issue. If two clients connect via OpenVPN (bridged), they can access each other without any problems, but neither of them can access the server, nor any system behind it. I am fairly sure it is a Shorewall issue, but I am very new to Shorewall, having

Hi, i have a huge problem ;] I have redirected port 69 from NET (internet) IP 212.122.68.129 to the local network (masq) 192.168.0.3, that all queries from internet goes to local network PC.

(Shorewall 1.4.4b; running the Mandrake edition.)

Hi, I''m running RH9 Linux and I''m having a slight problem with shorewall, i originally set it up as a two card configuration, but i have now bridged the connections in an attempt to get my WiFi network communicating with the wired network (eth0 and wlan0).
