Hi, I''m having issues with policing my incoming traffic by matching packet marks made by iptables. I''ve checked as many sites and guides as I can find, and I seem to be doing the exact same thing as they all are, but there''s still no success. As such, I was wondering if anyone can have a quick look to see if I''ve done anything obviously stupid? Essentially, I

I'm replacing an ancient Solaris 'ipf' firewall/router with a brand new CentOS 6.3 system. In the olden days, I successfully used the attached iptables script (as /etc/rc.local) on Red Hat 5.x systems, but this doesn't seem to be quite working on the new system. Specifically, while it seems to be routing ok, you cannot connect to anything on the inside net (e.g., with ssh or

Hello i''m having some issues trying to match packets using iptables mark, iproute filter and tc filter.- i mean, when i do iptables -t mangle -A INPUT -p tcp --dport 80 -j MARK --set-mark 20 iptables -t mangle -A PREROUTING -p tcp --dport 25 -j MARK --set-mark 10 iptables -t mangle -A FORWARD -p tcp -i eth0 -o eth1 --dport 25 -j MARK --set-mark 10 $TC qdisc del dev $INET_IFACE root $TC

Hi there, I have a little problem. I had this some months ago but didn''t solve it back then. I have patched my kernel with Layer 7 support and patched my iptables to support it, too. Now I inserted this line in my firewall script on my router for testing purpose: $IPTABLES -t mangle -A POSTROUTING -o $INET_IFACE -p tcp -m layer7 --l7proto http -j DROP It works, BUT only if the

Can you list more than one interface in the 'interfaces' config option? I have two interfaces, one that does nmbd and smbd to my LAN, and another that will browse-sync with a remote samba machine with the same configuration of two network cards. I'm looking to do something like this: interfaces = eth1 $LAN_IP/24 127.0.0.1/24 eth0 $INET_IP/24 bind interfaces only = yes Thanks,

Rowland, Did some editing in smb.conf that I had to reverse. Now I'm back to being able to connect with the firewall disabled. When I enable the firewall I get as far as windows network -> workgroup but no connection. I have only the rules you recommended in your last email. Louis, The information you requested is below: martin at radio:~$ dpkg -l|egrep "iptables|ufw" ii 

Hello, Is there a way to route p2p traffic on a separate ISP connection, just as you would choose a separate connection for http traffic? I tried all sorts of setups based on: http://www.braindump.dk/en/wiki/?wikipage=PolicyRouting but with no luck. Please help :) (ipp2p is up and running) _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

I found the problem! It was me and it was dumb... This was the network layout: 10.10.10.0/24 1.2.3.0/27 10.10.10.n internal hosts | <----+-----+--------+ +-------+------>to the Internet | | | | Proxied | | | H.323 device Firewall Router eth1 eth0 1.2.3.11

Woops - my fat fingers hit the send key before I could put in a subject a minute ago. Hello - I am using kernel 2.4.27 and running into behavior I don''t know how to explain. I have 2 relevant interfaces. eth0 is external, eth1 is internal. My internal LAN is 10.10.10.0/24. My External range is 1.2.3.0/27 (dummied up). I have an H.323 videoconference device inside my internal

Here are some notes I have about Linux bridging. I''ll try to separate what I know I know from what I think I know. Let''s say I want to bridge eth0, eth1, and eth2 together, all with an IP Address of, say, 1.2.3.2. This is how to do it: echo "Setting up br0 to bridge eth0 with eth1 and eth2" /usr/sbin/brctl addbr br0 /usr/sbin/brctl addif br0 eth0

Hello everybody. I''m running linux 2.6.19 with nth match to alternatively snat outgoing connections to two different ip addresses for load balancing between two adsl lines: Here is: $IPTABLES -t nat -A POSTROUTING -s my_ip --protocol tcp -m multiport --dports 80,443 -m statistic --mode nth --every 2 -j SNAT --to adslA $IPTABLES -t nat -A POSTROUTING -s my_ip --protocol tcp -m multiport

I put a bridging firewall together last winter (with some help) and have it= in production in front of a couple windows web and mail servers for going = on 6 months now. I used Fedora C1 with 2.4.22 kernel and 0.9.6 bridge-utils= . The bridge has solved a lot of security headaches. I use a modified start= up script written by David Whitmarsh that has worked really well. http://ww=

Hello - What I want to do seems very simple - I want to make sure any H.323 traffic gets processed before anything else entering or leaving this network. The network has a videoconferencing device on the LAN at 192.168.16.4. A Linux firewall NATs an external IP Address to this internal address and I have appropriate SNAT and DNAT rules that work. The NAT and connection tracking rules all work

Hello guys I don''t know if this thing has been posted before (if it was , please forgive me). I have 7 computers at home and I want all of them to have access to the internet. In order to do that , I set up a linux router (2 network cards) as a usual router (eth0 : 82.77.69.75 - internet connection ; eth1 : 192.168.10.1 - local network) . The other computers have ips ranging from

Hello! I''ve put some questions on this list some weeks ago and I''ve got good answers. Thank you! Now I''ve finished my (beautyful) script and I ran it on my router... About my script: It routes packages based on their destination on the Internet. I have about 1650 preffered destination networks listed in some file. The script read this file and marks every package for

Hi, I just migrated my office's server from Slackware64 14.1 to CentOS 7. So far everything's running fine, I just have a few minor details to work out.
