similar to: Routing packets over multiple links (NICS) all on the same ISP all with same gateway.

Hi, I have a linux box which balances load between two interfaces ( say WAN1 and WAN2). I have masquerading on for any request coming from LAN to the outside world. The setup is in such a way that WAN1 drops packets with source ip belonging to WAN2''s network and viceversa. For some strange reason, I find that packet coming out from the WAN interface has source address of WAN2 and

The LARTC howto correctly describes load balancing and split access for traffic from a machine with multiple ISP connections (http://www.lartc.org/lartc.html#LARTC.RPDB.MULTIPLE-LINKS) -- *provided* the traffic originates from the machine itself (i.e. traffic regularly handled by the INPUT and OUTPUT chains of iptables). When forwarding traffic from an attached local network, the following

Hello people: I''m new in the forum. I''ve implemented the script for load balancing of "Linux Advanced Routing & Traffic Control HowTo" and I''ve a question: When I run the next command : "ip route" I get the folowing information: -------------- 192.168.0.32/27 dev eth0 proto kernel scope link src 192.168.0.33 192.168.0.96/27 dev eth2 proto

Hello all, Tomas Bonnedahl and I recently corresponded about a rather odd behaviour with routes in ancillary routing tables. We both receive a "Network is unreachable" error when we try to add gatewayed routes to ancillary tables and the main routing table does not contain an entry for the gateway IP. It seems that unless a route to the gateway IP exists in the main routing table, I

Hi, I have searched the archives on the topic, and it seems that the list gurus favor load balancing to be done in the kernel as opposed to other means. I have been using a home-grown approach, which splits traffic based on `-m statistic --mode random --probability X`, then CONNMARKs the individual connections and the kernel happily routes them. I understand that for > 2 links it will become

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

Greetings routing folks, I want to use the netmask 255.255.255.255 to insulate (not quite isolate) machines on a shared subnet from each other. This works just fine on win XP, but Linux iproute will not acccept the gateway address in one step -- neither on the command line nor via DHCP: Here''s the interface, set up with a netmask of /32: # ip addr ... 2: eth0:

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:

Hi, I am tring to us ip route to load balance between two interfaces. ip route add equalize 10.200.1.0/24 nexthop via 10.200.0.2 dev neta nexthop via 10.200.0.2 dev neta2 Where neta and neta2 are gre tunnels. Testing show that packets travel in a single sided manner. Do I need to use the multipath (IP_ROUTE_MULTIPATH_CACHED) module? thx jason

Folks, Ive got two ISP connections that I am using with: --- ip route add 192.168.200.0/24 dev eth2 src 192.168.200.11 table connection1 ip route add default via 192.168.200.1 table connection1 ip route add x.175.244.0/24 dev eth1 src x.175.244.2 table connection2 ip route add default via x.175.244.1 table connection2 ip rule add from 192.168.200.11 table connection1 ip rule add from x.175.244.2

Hi. there is a way to MARK udp VOIP (SIP) traffic, in order to put in a highest prio class ? Traffic flow seems start on udp 5060 port, but next both server and client seems jump to a random(?) port. I can''t use CONNMARK because is udp traffic. I only see a pattern for L7 patch in order to SIP traffic identification , but I run 2.4 kernel series . When you patch 2.4 kernel with

Hi, I am currently using a 2.4 kernel with multipath routing patch v5 to send outgoing packets in a 1:1 ratio over two lines, however the lines do not actually have equal upstream bandwidth, one has 800kbit and the other 600kbit, so ideally I would like to send packets in a 4:3 ratio, is there anything in 2.6 or a patch for 2.4 that could be used to do that? I tried this ugly hack but it

Hi all! On http://lartc.org/howto/lartc.adv-filter.html I read that a classifiers available bases the decision on how the firewall has marked the packet and on http://lartc.org/howto/lartc.qdisc.filters.html the following example: "tc filter add dev eth1 protocol ip parent 1:0 prio 1 handle 6 fw flowid 1:1" "iptables -A PREROUTING -t mangle -i eth0 -j MARK --set-mark 6" My

Hi, I have a linux server running kernel 2.6.19 that is connected with 2 seperate 100Mbit links to the same isp: +---+ +---------------+ | I | +---------------+ | | | S | | | | eth0 --+--------------+ P | | |

Hi all :) there is somekind of strange Routing problem that im getting with Linux-2.6.16 and iproute 2.6.16 , when i use command like : ip route add default nexthop via 1.1.1.1 dev eth0 nexthop via 1.1.1.2 dev eth1 all packets goes on 1.1.1.2 ( always last interface ) , whats is the problem ? this situation also tested with equalize flag , on two physical interface and etc ... -- Lady Luck

Dear List. I try to build multipath connection w/ load balance to internet with two different gateway; My system is RH-8.0 with iproute-2.4.7-7.90.1.rpm and Kernel-2.4.26 (patching with Julian A. patch),and follow guide from http://www.linuxvirtualserver.org/~julian/nano.txt, The problem is; when i try to connect to Internet form gateway machine it;s success , but only one interface is

Hi, i want to do load balancing of 2 ISP's Everything is set up OK but one of the ISP's is loaded on 100% while the other is utilised on 1 - 5% I've read about Julians patches but they stop at 2.6.14. Is anybody aware of similar patches for higher patchlevels. 2.6.14 is not suitable for my setup Thanks for reading :) -- С уважение, Владимир Витков http://www.netsecad.com
