I''m attempting to setup Squid as shown on: http://shorewall.sourceforge.net/Shorewall_Squid_Usage.html#DMZ The firewall is a Bering 1.0 firewall running Shorewall 1.3.11, Red Hat 7.2 on the server in the DMZ. I''m not seeing the requests come in to the server using tcpdump. The server is 192.168.2.1 connecting to eth2 on the firewall, the local traffic I''m trying to

I have problem getting answer on http request from all my local subnets but not from local subnet. Ping and requests on ports 21 22 23 25 110 works fine.

Local subnet is 192.168.6 Dec 29 09:52:40 zinfsrv2 kernel: Shorewall:loc2fw:ACCEPT:IN=eth0 OUT= MAC=00:09:6b:07:ca:cc:00:10:b5:fa:bd:71:08:00

Hello all, Yesterday I noticed that my system was "leaking" traffic towards the 10/8 network, I have shorewall installed on multiple machines ranging from single interface devices to ones with 10+ interfaces. I tested all the boxes and they are showing the same behavior. All systems are CentOS 3.4, 2.4.21-27.0.2.ELsmp. Shorewall version: 2.2.1 For the host mentioned is a single

Hi My situation: I have two pc''s with public ip''s (192.159.56.206(webserver) and 84.196.123.65(mail-gateway)) in the dmz. The firewall (84.196.123.66) is configures with proxyarp, so nothing is changed on the pc''s from when they were not behind the firewall (i.e. they don''t have the firewall as gateway (and they each have different gateways, only 84.196.123.65

Dear List! I use a shorewall 2.0.8 on a Debian sarge system. I use a DSL connection to the Internet (ppp0 - eth1 to the modem) and a bridge to the local lan. The bridged config i''ve made with bridge.html from the shorewall site. The Bridge is between local net and a openvpn tap device. This works. I ccan make tunnels, and a can make a lot of things through the firewall. I can get a list

Hello! I am using shorewall shorewall-2.0.11-1 on fedora core2 (iptables-1.2.9-95.7). My box has 2 physical nic´s plus one virt. ipsec interface for a freeswan-vpn connection. A few days ago, portsentry spit out a lot of connections from windows clients (port 135, 445). Ooops. I review my shorewall settings but could not find a mistake. So I took a win-client and established a second

Hi, Trying to figure out why I cannot get access to dell.com Their site is up because I can browse using a different firewall. Trying to find out where the logs are located and what log files it would write to if it were to deny browsing to a website. I can see the [UNREPLIED] when using the shorewall status. Was hoping to know what logfile it is writing it to. Thanks in advance, Elmer

I apologize for the first message. :) --------------------------------------- I have an FTP server running in the DMZ section of my home network. It uses port 23000 for connection and ports 19990 to 19994 for data transfer. I have setup the following rule for outside people to connect to it: DNAT net dmz:192.168.2.2 tcp 23000 I''m at work right now and I can''t use

Ok, I''ve flogged this issue probably longer than some of you can stand by now. (remember, I''m the nut trying to use a PPro200 to support ~500 users on a 10Mb internet link :o) To appease those who think I''m nuts, I am ordering a new firewall shortly to allow for future growth. (probably a Dell PE750 with P4/2.8 and dual GE nics.) However, since I have yet to prove

Hi everybody I have a Problem with Masquerading from my local net (loc) to my VPN (loc2). I can reach every Service from loc2 in loc, but I can''t get reach any service from loc in loc2.

I''m having a problem with the Shorewall firewall and CUPS printing interfering with each other. My Linux firewall machine is acting as both a CUPS server and client for all of my tests. Shorewall 2.0.13 CUPS 1.1.22-2 Linux kernel 2.6.9 CUPS was working fine to print to my Epson C84 (network connected via a Netgear PS101 print server using lpd://PS101.IP.address/raw ) until I

Hello: I just started using Shorewall this morning and must say that I''m very impressed. Much nicer than what I was using previously. I love the ability to type ''shorewall logdrop ww.xx.yy.zz'' and completely block a particular IP address. However, the log part doesn''t happen. When I look in the logdrop chain, there is no LOG prefix. I''ve looked

This is a minor release of Shorewall. WARNING: This release introduces incompatibilities with prior releases. See http://www.shorewall.net/upgrade_issues.htm.

This policy will cause Shorewall to assume that there will never be any traffic between the source and destination zones. b) Shorewall no longer

I have defined a Home zone and placed it before the Net zone. Defined a host 192.168.174.242 as a trusted host. Now if I ping from 242 to my fw it works just fine (also tweaked the norfc1918 file). Thing I do not understand is why if I try pinging or FTPing from FW to 242 I hit the all2all reject rule ! I tried reading the rules and from the INPUT chain I see a eth0_in chain which in turn

I have tried (RH7.3/shorewall-1.3.12-1) both of the following in shorewall.conf to eliminate ''rfc1918'' logging into /var/log/messages: RFC1918_LOG_LEVEL=debug RFC1918_LOG_LEVEL=notice Neither appear to eliminate the logging. Here''s what the ''logdrop'' chain shows: 1 229 LOG all -- * * 0.0.0.0/0 0.0.0.0/0 LOG flags 0 level 6 prefix \
