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. 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

shorewall Dom0 config using Xen's default setup -- correct?
Hi all, The first couple of xen machines we setup used the default xen bridging setup for dom0. I am sure there are many other people out there with this setup. Now that I know a bit more there are probably better ways out there to configure the xen box for firewalling, most notably assigning the red card to a domU and running shorewall in there. But in the meantime I would like to further

Setting up a routed DMZ
Hello all, I''ve read the shorewall guides and browsed through the mailing lists, but I haven''t been able to find out if the following is possible or not using shorewall. Our provider has given us 16 IPs + 4 in a separate range for our uplink. I would like to replace that router with a Linux box running shorewall with three interfaces. I want the DMZ to be a standard, routed

Hub/Spoke OpenVPN can't communicate from Client A to Client B - FORWARD:REJECT:IN=tun0 OUT=tun0
Hi, I am running OpenVPN where i have one central hub VPN server, and multiple spoke VPN clients. I can ping from each client to the server and each client to computers on the subnet which the server resides (192.168.2.0/24) so it works ok there. I cannot however, ping from one client to another client. I guess the packet path would go: clienta -> vpn -> shorewall/router -> vpn ->

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

creating a static route (SUSE 10)
Hi, We have a shorewall firewall running on SUSE 10. We have three nic''s, Lan, DMZ and Internet. We also have a Cisco Pix 506e. We moved from sending all our traffic through the pix to using the Suse box yesterday. The PIX is in the DMZ, with a connection to the LAN switch, the idea being that VPN users can connect to the pix to the lan. The Pix is on the 10.0.1.x subnet, the lan is

shorewall dynamic zones confusion
Hi, I''ve been successfully using shorewall in our K12 school since the 2.x days initially on Mandrake and now on Debian. Because of that my config has got quite complicated. The firewall has a working MultiISP setup with four interfaces (I''ve renamed them with udev to easy their identification): lan-if, dmz-if, snt-if and dnt-if (one of the providers (the one on dnt-if) is a DSL

Hi I wonder if you can help... I have setup shorewall(2.2.3) under debian on a machine that has 4 network ports... the idea is that there is 1 WAN port, 1 DMZ port, and 2 LAN ports, 1 LAN port has static NAT setup for selected incoming connection from trusted sources, and the second LAN port I am trying to setup using masq NAT as it only requires outgoing connections, no incoming. the static NAT

Yikes! Routing issues!
We switched over from a bordermanager firewall to a shorewall firewall. Some stuff is not working now. I realized that I had not created the route for the network that is not working however once I created it, it still didn''t work. Most of our network is fine however some pieces are not working.
