similar to: Two ISP load balancing + One ISP'' subnet explicit routing

hi i recently searched in the mailinglist archive and found similar problems, whose solutions helped very much, thank you. i have the following scenario: a firewall with one lan interface eth0 10.1.1.1/24 and two uplink interfaces eth1 10.2.2.1/24 eth2 10.3.3.1/24 each uplink interface does SNAT: iptables -t nat -I POSTROUTING -o eth1 -j SNAT --to-source 10.2.2.1 iptables -t nat -I POSTROUTING

Hi all, I have implemented a solution with a machine balancing the network load between two DSL providers as is explained in the LARTC Howto. It is apparently working correctly, but i have some problems. The problem is basically that some packets go out by each ADSL interface with the source address of the other ADSL interface. I think that the routing based on source address isn''t

Hi, I have a linux-box with 3 eth, 2 of us go into 2 ISP. My localnet is masquerade with this rule: Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination SNAT all -- 10.0.0.0/16 anywhere to:211.56.233.186 SNAT all --

Hello Everyone, I configured a server for a friend's Internet cafe. He has 2 ISPs. Here is what I did: ## NAT -A POSTROUTING -s 10.0.0.0/255.255.255.128 -o eth2 -j SNAT --to-source 82.77.148.83 -A POSTROUTING -s 10.0.0.0/255.255.255.128 -o eth0 -j SNAT --to-source 83.103.190.175 ## Removing default routing /sbin/ip rule add prio 50 table main /sbin/ip route del default table main ##

here''s the setup (two dsl - same provider) +-----> link1 LAN----- linux box --| |----------internet +-----> link2 the setup is ok in terms of the failover requirement. the other link takes over when one is down. however, there is a very noticeable lag when both lines are up. i''ve tried changing

Hi, This is the first time I write to the list. My english is not so good, but I hope I''ll be understood. I have 4 adsl routers, plugged on a linux box, and this box e used to connect to a local network. The linux box has 5 NICs. eth0: local network inet 10.0.0.56/24 brd 10.0.0.255 scope global eth0 eth1: adsl router 1 inet 192.168.254.1/24 brd 192.168.254.255 scope global

Hi, I am connected to two DSL providers (DSL 1 - 1Mbps downlink/384kbps uplink and DSL 2 - 2Mbps downlink/512kpbs uplink) I would like to only allow ftp, pop3 and http via the DSL 1 and only smtp, ipsec and pptp via DSL 2. How can I do so? Can I use iproute to route these protocols? Below is my ip routing: - # DSL 1 ip route add 2.2.2.208/30 dev eth0 src 2.2.2.210 table 1 ip route add

I have 2 providers, each on a separate interface, and a LAN on the third interface. After I do the load balancing, only one line is used and the traffic gets through very hard. Also, a simple command, like iptables -t nat -L, takes very long to show the output. Does anyone know what could be wrong? I list my outputs here: taurus:~# ip route show all 192.168.2.0/26 dev eth0 proto kernel scope

I''m using a 2.6.20-15-ubuntu (shipped with feisty) kernel with Julian''s patches applied and it''s my 3rd day with tc, ip, ifconfig and the rest ;). Got 2 ADSL uplinks. What I need is an ability to manually configure uplink usage, so nothing like bonding by default. Failover is meant to be provided via a shell script at the next step. Here is my config: == # no need for

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.

I''m trying to connect to two ISPs the connections are as follows: Eth0 IP: 192.168.1.1 Mask: 255.255.255.0 Eth1 IP: 216.167.217.241 Mask: 255.255.255.0 Eth2 IP: 216.167.208.40 Mask: 255.255.255.0 Here are the commands to set things up: #Load modules insmod /lib/modules/2.6.19.2- pyramid.metrix.net/kernel/net/ipv4/multipath_drr.ko insmod /lib/modules/2.6.19.2-

I am running 2.4.20 with Julian Anastasov''s patches (routes-2.4.20-9.diff), iptables v1.2.6a, iproute2-ss010824 on Debian. I have set up our internal gateway to multihome 2 T1''s as described in http://www.linuxvirtualserver.org/~julian/nano.txt . The only difference is that I use multiple IP''s on the external interfaces. EXA A.B.C.225 --------------------

Hi, I am new in LARTC list. I had intermediate skills in networking. What I tried to do: Use 2 links with loadsharing + falt toletant (to add bandwitdh) ok ! I am use Debian Etch in router/fw With kernel debian default + routes-2.6.17-12.diff patch The Problem: The iproute2 just route thought the last gateway of nexthop rule. I was running tcpdump in 2 terminals, tcpdump -nni eth0 ...

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 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

Hi, I have a client connected to the ''net through 3 ISP''s. Have set up a Linux box to do routing and load sharing for the 3 connections. A fourth interface is connected to the LAN with private IP addresses. Am using iptables to SNAT traffic to the appropriate IP depending on the interface the packet gets routed onto. The setup looks something like this: Interface IP
