similar to: Multiple uplinks through single ethernet

For easy reading: http://www.karthaus.nl/r/ Hi, We used to have 1 single ip range (1.1.1.0/24) that had one uplink to a = switch of the colocation provider. Recently we got a second range 2.2.2.0/24 and a redundant uplink = directly on two routers. But our switch does not have spanning tree = protocol support so we cannot use them redundantly. We have set up the switch to have a vlan for both

Hi, I read the howto of iproute, I have the same case with HOWTO, the difference is that the whole incoming traffic goes through interface 0, the other difference is that I do not want to balance the out going traffic, because I have specific networks to take it throughout another interface. Mi Case IF1 --> Input and Output IF2 --> Only aoutput for three Network I need Help, How can I

Hi, I''m with a problem here on configuring our server to use multiple uplinks with different providers. The packet goes though on my way, but there is some lost packets that I don''t known where it''s going and causing my link to goes slow and stop sending/receiving data. Here i''m listing the route tables and the rules. It''s only for 1 IP.

I am hoping that someone with more experience and knowledge than I can assist me in finding a solution ;) We have a RedHat AS4 box with 5 interfaces. Two interfaces serve two different networks and two interfaces connect to two different uplinks. The fifth interface is our management interface. Since a picture is worth a thousand words I attempted to come up with a diagram:

Hi! I had two uplinks till today. We stopped one of them today, so i thought i could share my experience. (it is maybe useful for somebody) I hadn''t managed to configure it using a LARTC howto, but the Nano-howto (http://www.ssi.bg/~ja/nano.txt) and julian''s kernel patches. I had some problems with icq connections, because it is a two step connection (It is just theory). 1.

Hi folks, i spent my whole day trying to set up my linux router using load balancing with multiple uplinks. I mainly focused on the nano howto, but somewhere I have a big mistake within my head. Basically the load-balancing is working, but not on a per-connection basis - just on a per packet basis. Practically this is not usable of course <g> But as far as I understood it should work..

provide me complete detail of your linux box like firewall script (iptables script), kernel''s .config file, multigatway file (i.e. /sbin/ip ....... commands file) so i can check and try to resolve your issue. sonu.... --------------------------------- Do you Yahoo!?

Hi, I configured a router box to use 2 providers, as described in the HOWTO. (Apendix 1) I want to use both links to reach a single smtp server. As I read in the kptd and in some old messages of this list, doing a SNAT in the postrouting chain comes _after_ the routing desision. So I guess the following lines I''m trying to use are wrong. (See Apendix 1) What can I do to have multiple

Hi. Contents: 1) Introduction 2) 2 Questions * Introduction: I used this HOWTO to use multiple providers. http://lartc.org/howto/lartc.rpdb.multiple-links.html The box is a load balancer, using the Linux Virtual Server. We have a problem with lost connections, and it seems you get issues when you combine this setup with DNAT [1]. The proposed solution [1] is to use these rules to mark

hi all, we were trying to configure our system with 2 ethernet catds connected to two different providers using iproute2 so that it recieves and transmits data from both of them. We have followed the configuration as given on lartc''s howto But the most wierd part of the story is that after we restart the system (We have put the script in rc.local) the system works fine and we can ping

hello, my name is Denny. I am new in this list. I am trying use multiple uplinks as describe in the lartc documentation (http://lartc.org/howto/lartc.rpdb.multiple-links.html) with squid transparent proxy in my gateway server. let me draw the configuration : /----------------- -----DSL1-----| \ |Transparent proxy |----Local network -----DSL2-----|

Hello, I''m trying to achieve the following. 2 ISP''s and 1 LAN with failover. So, when 1 internet connection fails the other need to take over. I''m aware of the restrictions. The current sessions are lost. I did this before, one and a half year ago or something. But at that router wasn''t failover. Now i''ve read the nano howto and followed it.

Hello everyone. I've stumbled upon a strange networking issue with multiple interfaces on CentOS 5. The network setup is just like the diagram in http://lartc.org/howto/lartc.rpdb.multiple-links.html It looks like linux is not routing correctly outgoing packets on interfaces different from the one of the default gateway, but instead broadcasts an ARP request on the link, looking for the

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

Hello! I have set up a LINUX router with two seperate uplinks to do load balancing. I made all the configuration after the "NANO-HOWTO to use more than one independent Internet connection" document. I patched my 2.4.24 kernel with patches, described in this document. My configuration is: --------------------------------------------------------------- #!/bin/bash

Hello, I am trying something crazy here. I have gone through the old archives, lartc.org and lot''s of documentation, but still something is wrong. Here is the situation; The server is Fedora core 2 running kernel 2.6.5 I have 2 uplinks to two different ISP''s. (It will be 3-4 in the future). These ISP''s should serve the bandwith to local clients with multiple subnets.

Been running this for quite a while and noticed that have intermittent problems getting out. Find that if I ping the same site from 2 computers it may work on one and fail on the other. Also was surprised that some time they are going out different interfaces at the same time. Seems to work all the time from the firewall. Running 2.6.10 kernel with the multipath routing patches on a debian

Hello all, I''m writing to the list, because I have a problem setting up my routing that I''m unable to overcome. 1. The situation: +-------------+ +-------------+ | actaea | eth0 | ilex | | 192.168.1.4 |------ localnet ------| 192.168.1.1 | +-------------+ 192.168.1.0/24 +-------------+

I think that source routing is setup correctly: I can ping/connect to my router through both interfaces from outside no matter how I setup default routing on it. Marcin Z -- Configure bugmail:
