I''m noticing some weirdness in my ulog files with version 2.0.10. Here is a portion of the log: Jan 7 11:01:37 rancor Shorewall:loc2fw:AllowWOL: IN=eth1 OUT= MAC=ff:ff:ff:ff:ff:ff:00:0a:95:b2:11:4c:08:00 SRC=192.168.0.100 DST=192.168.0.255 LEN=97 TOS=00 PREC=0x00 TTL=64 ID=44155 CE PROTO=UDP SPT=631 DPT=631 LEN=77 Jan 7 11:01:39 rancor Shorewall:loc2fw:AllowWOL: IN=eth1 OUT=

Hi everyone. I am so baffled by the following problem: Office 1 is using ADSL and it is building a VPN tunnel with IPSEC to Office 2. Both ends are using shorewall/freeswan firewalls. Diagram: Office1 fw --- VPN TUNNEL --- Office2 fw --- cisco router ----- VLANS | DMZ Office 1 has the following interfaces: 2: eth0:

How would I use Big Brother with Shorewall and my loc and dmz zones to monitor hosts in both zones? If Big Brother''s server is on my LAN (loc) is it "safe" to forward the bb port from the dmz to the LAN? What would the security risks of this be? Common sense says that it may not be a good idea to forward stuff from the dmz to the LAN, but I''m inexperienced and unsure

Hi. I am trying to force some traffic that goes to address 203.7.93.94 through a VPN tunnel. I use freeswan 1.98b and Shorewall 1.4.6c in one machine. The 203.7.93.94 is in the DMZ on the other end. (Both ends use the same shorewall and freeswan). I have successfully set up a tunnel between the two network (using a point to point topology, not hub). I added a static routing that redirect

I did some looking on the mailing list archives and can''t seem to find exactly what I need, I''m also having troubles figuring this out on my own, so if anyone has any advice, tips, whatever, that would be great. I''ve got a machine with 3 network cards in it, one for a DMZ (with 3 machines on a switch each with a real IP address), one for the local network on a

Ok folks, here goes.. I have been boggling with a problem for the past week, and still haven''t found a solution.. I''m trying to route traffic from two providers through a Linux machine. But that is not the problem. The ISP''s have provided me with a WAN IP class for both of the lines, to be routed into a DMZ where the machines a to respond to their respective

I would like to place an exchange 5.5 server in my DMZ. Can anyone tell me how I can set this up to allow LAN clients to be able to connect to Exchange and also so I can admin the box from the LAN with Terminal Services? Thank you.

I am trying to add a machine into my dmz. It is the first machine I''ve ever added to this dmz and fro some reason I cannot establish communication between the dmz and the machine. Here is an example of my setup: ISP router --> firewall (eth0) firewall (eth1) --> local network firewall (eth2) --> DMZ eth0 and eth2 have public IP addresses as does the machine I just added to

Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

Hi, in a three interface firewall I have eth0, loc, 10.1.5.1/16 eth1, int, 200.41.61.228/29 eth2, dmz, 192.168.1.1/24 (un)fortunately I got a group of public ip?s to use, so here is my problem in the dmz I have 192.168.1.3 redirected from eth1 alias 200.41.61.226 (a web server, works perfect). I am trying to set up a mail server also, a different machine, so I can?t use proxyarp, as with this,

My sincere apologies to all on this list. After looking for returning packets with tcpdump and not finding ANY I called our provider to confirm our IP assignment. The IP range that I was given by my boss was incorrect. After adjusting the ip assignments, everything is working perfectly. Thank you all for your time in troubleshooting this, and I hope to be able to return the favor at some

I''m trying to get Shorewall to use ulogd for logging, but I''m not seeing any logging in either the file I set up for logs, nor in /var/log/messages (where the logs used to be). I''m running a stock Debian 3.0 woody system, with a custom 2.4.21 kernel. I used all the settings as described on shorewall.net when configuring the kernel. ulogd (0.97-1) and shorewall

Hello all, Name is Andrew and in desperate need of some info.

hello there, im running a 3interface inet, dmz, loc. i have some public ip addresses. one public address is the router of the provider, the second one is the linux box running shorewall. all other public interfaces are on the dmz nic with proxy-arp. now whenever i do a traceroute (the dmz boxes are windows, icmp traceroute) the very first hop gets timeout/stars, then the router of the provider

Dear all: Im using shorewall 2.0.3a (debian) w/ ULOG. shorewall starts ok, and the firewall is running, but nothing is printed on the logs. I try, for example, to do a connection to a port that is opened on the server but closed by the FW and I get a connection refused. If I stop the firewall, this port is accesible from the outside. I think I''ve followed all the steps on

From reading the documentation, I understand that it is recommended to put servers that may be at risk in a DMZ served via proxy-arp. In this case, the local clients that are behind a NAT would have their connections to the DMZ masqueraded, yes? Is there any way around this that would still be considered secure? Just looking for advice. Thanks, A.

Tom, I have used Shorewall now for 4-5 weeks and I''m really impresssed by the power and flexibility of the package. I''m running Two-Interface Firewall with a MASQ''ed Shorewall (on SUSE 8.0) to protect my LAN (5 WIN XP''s and a WIN2K Server acting as PDC). The Shorewall Linux box has two NIC''s (eth0 to Internet and eth1 to my LAN Switch) and is also
