DROPPED SYN Packets
Hi, One person, trying to access my website has troubles doing so. All other users do not have a problem. I have a cable modem, with a shorewall 1.4 machine behind it. On the second interface of the shorewall machine I have a few machines, of which one is the webserver. Checking the logfile I see the following messages: Aug 30 21:24:16 gatekeeper kernel: Shorewall:rfc1918:DROP:IN=eth1

Shorewall and CUPS printing interference
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.

vpn-zone wide open
Hello! I am using shorewall shorewall-2.0.11-1 on fedora core2 (iptables-1.2.9-95.7). My box has 2 physical nicĀ“s plus one virt. ipsec interface for a freeswan-vpn connection.

Intermittently denying access to webshop
Hello shorewall-users, we have a strange problem where some of our customers cannot access our webshop, but most of the customers can. I have been slowly eliminating possibilities and am now left with either the firewall (Shorewall 1.4) or the webshop server. What appears a lot in the logfiles is: Jul 26 11:51:04 gw kernel: Shorewall:logdrop:DROP:IN=eth0 OUT=eth1 SRC=84.128.198.240

Masq and such works, but I''m having a problem with my port forwarding. It works for port 22, but it doesn''t seem to work for any other port. I''ve turned

hopeless - smb over bridged firewall
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

Defining "trusted" hosts/nets on a single interface system
Ok, I give up. I tried, really hard, before asking but I must be the most stupid shorewall user on the planet :( My laptop runs a single eth0 interface and knows Net and Firewall as zones and the default "inbound" policies are Net->Any DROP and >ny->Any REJECT. Now at home I have my trusted 192.168.174.240/29 subnet which hosts my very trusted 192.168.174.242 host and I

Port forwarding on Shorewall box behind NAT ADSL router
Hi, Before I go any further, I''m no networking expert, and the sheer volume of documentation on the Shorewall website makes my brain hurt.. Some time ago I moved from an area with cable internet to an ADSL only area. While on cable, I''d set up an old P3 box running Gentoo as a firewall/gateway/file server, running shorewall (currently v2.2.3) and dnsmasq. I''d

Fixing to bite the dust?
I've been getting LOTS of messages like the below in the daily log, and from all indications, it appears to all be related to the cpu; the machine is just over a year old, and was the old vortex.wa4phy;net server from the downtown co-lo site. Aside from huge log files, and lots of other fluff, numerous problems of other nature have started cropping up. Anyone have any suggestions as to

Desktop Over NFS Home Blocked By Firewalld
Hi, Just installed CentOS 7 that serves a home dir automounted over nfs. SELinux is disabled. If I go to the client (oldish version of Fedora) doing su - username works fine and the nfs export is mounted and I can see all files and everything seems well. But trying to actually login to the desktop from the client machine does not work. It starts to login but then just hangs with a black screen.
