Hello, I have configured a load balancing router using Julian''s patches and as described in "nano.txt" for two ISP links as shown below. ISP 1 ISP 2 . . | | | | | | | WAN

Hi all! After that good thread "DGD patch not detecting dead gateway" I was able to set up a Load Balancing with ping based DGD (without Julian Anastasov patch). But now I''m facing a new problem and tried some options, with only partial solutions. I made a script based on http://www.mail-archive.com/lartc@mailman.ds9a.nl/msg16257.html (Thank you Manish Kathuria),

I have been successfully implementing load balancing gateways for multiple ISP links at various locations using Julian''s patches and as suggested in LARTC HowTo. At one location, one of the ISPs is providing connectivity through a PPOE DSL link which has to be dialled in everytime to connect. The gateway has been configured on a Fedora Core 3 based system and I have recompiled the

Hi there, i have some questions regarding CONNMARK and STRING modules for netfilter. I have a stateful firewall doing contraking, because i have two dsl connections doing load balancing. I have found a way to discriminate KaZaA traffic flowing via port 80 from normal HTTP traffic using the string match. I want to mark a kazaa connection and filter ir to a specific qdisc. I have been looking

Dear Sir, Please help me in building the right solution. My requirement is: 1st I want to club both ISP bandwidth to get 512kbps. 2nd, In normal condition, it should be in Load balancing. 3rd , In ISP Failover condition, traffic will automatically route to working ISP. What I have: I have installed the RHEL 3.0 with 3 Network Card. Kernel is 2.4.21-9EL I have the link from two ISP both

Hi, I''ve been implementing a load balancing solution using CONNMARK, based on solution described by Luciano Ruete at [1]. Gracias por el post y por apuntar en la dirección correcta Luciano! Once implemented, I''ve found that due to some reason packets aren''t properly marked (or improperly remarked) and sent out using the wrong interface. My topo setup is:

Hello everybody. i have the folowing problem: i have this in the top of PREROUTING chain in mangle table iptables -t mangle -A PREROUTING -j CONNMARK --set-mark 0 # rule 1 iptables -t mangle -A PREROUTING -m connmark --mark 5 # rule 2 iptables -t mangle -A PREROUTING -m connmark --mark 6 # rule 3 i think when packet is passing trough my POSTROUTING in mangle table

I saw this snippet from Daniel Chemko dchemko@smgtec.com Mon, 31 May 2004 09:30:43 -0700 # Egress marking (mostly for QOS operations) iptables -t mangle -A POSTROUTING -j CONNMARK --restore-mark iptables -t mangle -A POSTROUTING -m mark ! --mark 0 -j ACCEPT iptables -t mangle -A POSTROUTING -o ${if_inet} --dport 21 -j MARK --set-mark 0x111 iptables -t mangle -A POSTROUTING -j CONNMARK

Hi, A friend of mine has 2 lines of 512kbps terminated in two Linux boxes. He now want to remove those 2 boxes and have some device which will loadbalance the two ISPs and also have a failover arrangement. But he has agreed to give me a chance to do it on Linux for my own satisfication. Is this easy to do with lartc? How do I go about it exactly? I have very less time to do it since his

I am trying to get IPP2P working on my router. Thus far I can see connections being marked (see below), but they don''t seem to get saved or something. When looking at /proc/net/ip_conntrack, nothing has anything other than 0 for mark. The iptables commands for this are: iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j

Hi, I want to classify with ipp2p packets that I''ve captured with tcpdump. I send the packets with tcpreply. I had to create a bridge interface in order to enable the listening interface in promiscous mode and to classify the traffic mirrored to that. In this mode the traffic pass through the prerouting chain of the mangle table (on bridge). I want to used connmark for recognized flows,

Hi There, I am also trying to do the same for my network. I have two links from different ISPs and I want to configure a failover and load balancing Linux router. I am facing same problem here, that how to detect link failure and let Linux box switch the gateway. I know it works when the first gateway is physically down and not reachable. But what to do if my link is up but there is problem

Hello, This is on Centos 6 and not something I think is wrong with Centos 6 but I am looking to see if anybody else has experienced this and if there is solution. So thanks up front for indulging me. Because Linux makes routing decisions before SNAT it is causing problems when trying to use FTP with two upstream providers in a load balanced setup. Other than ftp, things seem to work OK. Below
