While I''m in temporary retirement, I''ve decided spend a little time experimenting with new things and making some updates to the web site. The biggest result of this effort to date has been: http://shorewall.sf.net/Shorewall_Squid_Usage.html This outlines how to use Squid as a transparent proxy running on the firewall, in the DMZ or in the local network. In the latter two

Hi, I am trying to configure the SMTP service on DMZ host. Added the rule: ACCEPT wan dmz:66.58.99.84 tcp pop3 - ACCEPT wan dmz:66.58.99.84 tcp 25 - ACCEPT dmz:66.58.99.84 wan tcp 25 - ACCEPT dmz:66.58.99.84 wan tcp pop3 - issued shorewall clear, shorewall restart, but still couldn''t telnet to the mail server

Anyone, willing to take a lead on this one, since Tom is taking a rest: " I am hosting all servers by myself. I have five static IP addreses with a DSL line. My DSL router from the ISP provider is configured as bridge, so no traffic is filtered. I checked the logs and getting: Jan 5 23:05:12 gw1 kernel: Shorewall:all2all:REJECT:IN= OUT=eth0 SRC=66.58.99.86 DST=216.35.73.164 LEN=68

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

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

That log message looks like someone (or some program) is trying to browse to moreover.com from your web server machine--it''s not a reply to an external request. You''d see messages like that if you were running some sort of HTTP proxy server (like Squid) on that box (although they''d likely be to multiple IPs, unless your users only browsed to p.moreover.com). It could

Two quick questions to the group: Anyone seen this before: Jan 14 02:55:45 gw1 kernel: Shorewall:all2all:REJECT:IN=eth1 OUT=eth0 SRC=66.58.99.83 DST=170.224.8.51 LEN=52 TOS=0x00 PREC=0x00 TTL=63 ID=38676 DF PROTO=TCP SPT=1735 DPT=80 WINDOW=5840 RES=0x00 SYN URGP=0 I mean my web server is trying to replay to some external host 170.224.8.51 (p.moreover.com) for some reason. What could be? It

To rephrase the question, "Can I use masquerading and proxy ARP in the same zone simultaneously?" It''s not a stupid question--I couldn''t see any reason why it wouldn''t work, but I had actually try it out to convince myself that it did (which isn''t a bad thing to do before posting the question to the list, by the way). In any case, the answer is

I am quite new to Linux and have moved (almost) from a windoze NT4 environment. My present configuration is running SuSE V 8.0 with KDE3.0.5 desktop on two machines, connecting with Samba to an NT4 PC, and an occasional laptop or other PC that connects locally to the network. After a deal of searching, researching, and seeking advice I have decided to use Shorewall as my firewall.

When installing Mandrake 9.0 with the higher security option you cannot ping any of it interfaces, localhost (127.0.0.1) included. All other connections to the system are fine, e.g. ssh, www, squid, etc. "shorewall clear" doesn''t help. Does anyone know how to turn this off for at least localhost and eth1?? Yours truly, Ben

Hi there. I have two samba servers, let's say srv01 and srv02. For that matter, both are Zentyal Server 4 and 8, respectively. In the srv01 there is samba version 4.1, which is in the network 182.168.200.0/24, and which is by the way also the gateway to both network. In the srv02 there is samba version 4.15, which is in the DMZ network 10.10.100.0/24 The first is an additional controller for

Hi everybody. I''m trying to configure shorewall folowing this manual: http://www.montanalinux.org/proxmox-ve-with-shorewall.html But with shorewall check it tells me thah: Checking /etc/shorewall/interfaces... ERROR: Unknown zone (dmz) : /etc/shorewall/interfaces (line 16) How can I define it in the zone file? thanks for the help. best regards, Santiago.

There have been a number of questions recently about Shorewall 2.0 and routing. In earlier posts, I said that Shorewall 2.0 would no longer alter the routing table as part of setting up Proxy ARP. I have been persuaded to take a different approach. In Shorewall 2.0.0-Alpha2, the HAVEROUTE column has been restored to the proxyarp file and a new PERSISTENT column has been added. If the

The Shorewall support page advocates including the output of "shorewall status" with problem reports that involve some sort of connection problem. I suspect that the number of people who feel comfortable analyzing problems through use this output is small. To help, I''ve created http://shorewall.net/AnalyzingShorewallStatus.html I suspect that the document isn''t

Please see https://bugzilla.redhat.com/show_bug.cgi?id=727648 for more info. Shorewall executes some bash code like the following: while read address interface external haveroute; do qt $IP -4 neigh del proxy $address dev $external [ -z "${haveroute}${g_noroutes}" ] && qt $IP -4 route del $address/32 dev $interface

OK one factor that I had not mentioned previously is this is my first time running Debian (yes I managed to do that since 1997...). Yesterday I found /etc/network/interfaces and understood what it does! My system is like the "About My Network" example except that I have 2 class Cs in the DMZ. >From what I understand I use the same IP on the NET and DMZ interfaces. I don''t

Hopefully this is an easy question.... I''m using a leaf router (bearing) running shorewall. Three interfaces net, loc, and dmz. Only one computer in the dmz and its being proxy arp''d. External and internal (net and loc) can reach the dmz but the dmz cannot reach the isp''s gateway and beyond, but can reach a system adjacent to the firewall.

I have tried unsuccessfully to run both Shorewall 1.2.x, 1.3.x with Proxy ARP on a Red Hat 7.2 machine. The machine was configured as the external firewall as per the ''belt and suspenders'' layout given at http://www.skippy.net/linux/firewall/ The firewall appeared to function correctly in all functions except proxy ARP, however I must say I did not test exhaustively.
